Abstract	Chronic headache affects a significant proportion of the population and can be caused by an underlying lesion or a serious condition. This case report describes a 38-year-old male with a history of chronic migraine headaches who presented with syncope. The patient was found to have bilateral papilledema on fundoscopic examination and a well-circumscribed, oval-shaped lesion located within the intraventricular septum on MRI. The lesion was identified as a colloid cyst and was surgically removed through endoscopic transnasal excision. The patient's symptoms improved significantly postoperatively, including the resolution of his chronic headaches and syncope. This case report highlights the importance of considering space-occupying lesions as a possible cause of chronic headaches, particularly when symptoms do not respond to conventional treatments. It demonstrates that an endoscopic transnasal resection is a feasible approach, even for large colloid cysts.

Abstract	Tracheomalacia refers to diffuse or segmental tracheal weakness. Most commonly, tracheomalacia develops after prolonged endotracheal intubation or tracheostomy. Surgical management is warranted in symptomatic patients with severe tracheomalacia. Relief of airway obstruction via stenting often provides immediate improvement in both airflow and symptoms. However, stent placement is associated with significant complications. Here, we present the case of a 71-year-old man who was brought to the emergency department with acute respiratory distress. The patient was known to have tracheomalacia with tracheoesophageal fistula. He had multiple medical comorbidities, including longstanding hypertension, diabetes mellitus, and asthma. The patient had a progressive decline in his level of consciousness and was admitted to the intensive care unit for further management. Despite the maximum ventilatory support, the patient did not achieve an adequate oxygenation level. The patient underwent tracheal stent placement by the interventional radiology team. The insertion was unsuccessful despite three attempts. The tracheal stent had migrated into the upper esophagus on the first and second insertion attempts. Because the patient was unstable to tolerate further attempts, the multidisciplinary team recommended the insertion of an esophageal stent to cover the tracheoesophageal fistula. Despite this, the patient continued to have air leakage with progressive worsening of his respiratory condition as he developed multiorgan failure and died. The management of tracheomalacia in the setting of the tracheoesophageal fistula may pose several challenges. The present case highlights an essential complication of stent placement with the stent migrating into the tracheoesophageal fistula, which is an unusual site of migration. A multidisciplinary approach is crucial in the management of difficult cases of tracheomalacia.

Abstract	BACKGROUND Small bowel hematoma is a rare yet clinically significant condition characterized by the accumulation of blood within the mucosa and submucosa layers of the small intestine wall. It can lead to complications such as bowel obstruction, ischemia, perforation, and even hemorrhagic shock. The etiology of intramural small bowel hematoma is diverse, encompassing factors such as anticoagulant therapy, coagulopathies, vascular disorders, trauma, and underlying systemic conditions. CASE REPORT We present the case of a 67-year-old man with a history of aortic valve replacement who presented with intense abdominal pain. Physical examination revealed generalized abdominal tenderness and black stools upon rectal examination. Laboratory tests indicated coagulopathy with a prolonged thrombin time. A computed tomography scan confirmed the presence of an intramural small bowel hematoma and hemoperitoneum. The patient's condition significantly improved within 48 h under conservative management, including nasogastric tube insertion, continuous monitoring of gastric aspirate, nil per os status, intravenous fluids, and analgesics. Warfarin was temporarily stopped, and fresh frozen plasma was administered for anticoagulation reversal. Heparin infusion was initiated once the INR became within the therapeutic level. CONCLUSIONS The occurrence of spontaneous intramural small bowel hematoma, although rare, demands rapid diagnosis and prompt, well-coordinated management. This case underscores the pivotal role of multidisciplinary collaboration in providing a comprehensive assessment and a tailored approach to treatment. While conservative measures, including careful monitoring and supportive care, have demonstrated favorable outcomes, the consideration of surgical intervention remains crucial, particularly in severe cases.

Abstract	Takayasu arteritis is an idiopathic vasculitis that typically involves the aorta and its major branches. It is more common in women and has the highest prevalence in Asia. Imaging studies are crucial for establishing the diagnosis and for determining the extent of the disease. We present the case of a 47-year-old man who presented with a complaint of anuria and generalized weakness for the last three days. He reported a history of generalized abdominal pain for the last two weeks. His vital signs were within normal limits, but the systolic blood pressure in the lower limb was lower by 60 mmHg compared with that of the upper limb. Notably, the pulses were very faint on palpation. Laboratory investigations revealed deranged renal function parameters. Ultrasound examination showed increased renal parenchymal echogenicity bilaterally with elevated peak systolic velocity of the main renal artery on spectral Doppler. Further investigation by computed tomography demonstrated near-complete thrombosis of the abdominal aorta distal to the origin of the celiac artery and extending to the common iliac arteries with the involvement of bilateral renal arteries. Immunological investigations, including antinuclear antibody (ANA), double-stranded deoxyribonucleic acid (dsDNA), cyclic antineutrophil cytoplasmic antibody (c-ANCA), and perinuclear antineutrophil cytoplasmic antibody (p-ANCA), revealed negative results. However, the positron emission tomography showed markedly diffuse and circumferential increased uptake in the walls of the aorta, subclavian arteries, and femoral arteries. The patient underwent successful endovascular treatment with catheter-directed thrombolysis. High clinical suspicion is required to identify renal artery thrombosis since the clinical symptoms are non-specific. Early diagnosis is crucial to allow for prompt therapeutic interventions.

Abstract	Background Urinary stone disease is a common reason for emergency department (ED) visits, and a computed tomography scan of the kidneys, ureters, and bladder (CT-KUB) is frequently used for diagnosis. The objective of this study was to estimate the positive rate of CT-KUB and identify predictors of emergency interventions for patients with ureteric stones. Methods A retrospective study was conducted to investigate the positive rate of CT-KUB for urinary stone disease and to explore the factors that determine the need for emergency urologic interventions. The study population included adult patients who underwent CT-KUB to rule out urinary stones at King Fahd University Hospital. Results The study included 364 patients, of whom 245 (67.3%) were men and 119 (32.7%) were women. CT-KUB revealed stones in 243 (66.8%) patients, including 32.4% with renal stones and 54.4% with ureteric stones. Female patients were more likely to have normal results than male patients. Approximately 26.8% of patients with ureteric stones required emergency urologic intervention. Multivariable analysis found that the size and location of ureteric stones were independent predictors for emergency intervention. Patients with distal ureteric stones were 35% less likely to need emergency interventions than those with proximal stones. Conclusion The positive rate of CT-KUB was acceptable for patients with suspected urinary stone disease. Most demographic and clinical characteristics were not predictors for emergency interventions, but the size and location of ureteric stones and elevated creatinine levels were significantly associated.

Abstract	Parotid gland metastases from distant primary malignancies are uncommon and present diagnostic challenges for clinicians. We present the case of a 65-year-old male with a history of clear cell subtype of renal cell carcinoma who presented with a painless swelling in the right parotid region. His medical history was significant for a right-sided renal cell carcinoma, for which he had undergone a radical nephrectomy five years ago. The patient's physical examination revealed a firm, non-tender mass in the right parotid gland region. Imaging studies, including ultrasound and contrast-enhanced computed tomography, confirmed the presence of a solid-enhancing lesion within the parotid gland. Fine-needle aspiration biopsy provided histological evidence of malignant cells with features consistent with a clear renal cell carcinoma cell subtype. This is consistent with diagnosing metastatic renal cell carcinoma to the parotid gland. This case highlights the significance of considering metastatic disease in the differential diagnosis of parotid swellings, particularly in patients with a history of remote malignancy. Systemic targeted therapy, with a tyrosine kinase inhibitor, emerged as an effective treatment option, emphasizing the importance of personalized approaches in managing rare clinical scenarios. Tailored management is crucial in optimizing outcomes for patients with parotid gland metastases, improving their overall prognosis and quality of life.

Abstract	Traumatic brain injuries are a significant public health concern often associated with immediate consequences. However, delayed complications can manifest, including rare congenital neural tube defects such as encephaloceles. We present a case of a 45-year-old male with a history of traumatic brain injuries who developed a posttraumatic frontal meningoencephalocele associated with cerebrospinal fluid rhinorrhea. This case emphasizes the need for vigilance in assessing patients with a history of head trauma for delayed complications, even years after the initial injury. Early diagnosis and intervention can significantly impact outcomes.

Abstract	Background: Sickle cell disease (SCD) is a genetic hematological disorder associated with severe complications, such as vaso-occlusive crises, acute chest syndrome (ACS), and an increased risk of thromboembolic events, including pulmonary embolism (PE). The diagnosis of PE in SCD patients presents challenges due to the overlapping symptoms with other pulmonary conditions. Our previous study revealed that nearly 96% of computed tomography pulmonary angiography (CTPA) scans in SCD patients were negative for PE, highlighting a gap in understanding the significance of CTPA findings when PE is absent. Methods: In this retrospective follow-up study conducted at the Salmaniya Medical Complex in Bahrain, we examined SCD patients with HbSS genotypes who underwent CTPA from January 1, 2018, to December 31, 2021, for suspected PE, but the results were negative. The aim of this study was to identify alternative diagnoses and incidental findings from CTPA scans. Experienced radiologists reviewed the CTPA images and reports to assess potential alternative diagnoses and incidental findings, incorporating an additional analysis of chest X-rays to evaluate the diagnostic value of CTPA. Incidental findings were classified based on their location and clinical significance. Results: Among the 230 evaluated SCD patients (average age 39.7 years; 53% male) who were CTPA negative for PE, 142 (61.7%) had identifiable alternative diagnoses, primarily pneumonia (49.1%). Notably, 88.0% of these alternative diagnoses had been previously suggested by chest radiographs. Furthermore, incidental findings were noted in 164 (71.3%) patients, with 11.0% deemed clinically significant, necessitating immediate action, and 87.8% considered potentially significant, requiring further assessment. Notable incidental findings included thoracic abnormalities such as cardiomegaly (12.2%) and an enlarged pulmonary artery (11.3%), as well as upper abdominal pathologies such as hepatomegaly (19.6%), splenomegaly (20.9%), and gallstones (10.4%). Conclusion: This study underscores the limited additional diagnostic yield of CTPA for identifying alternative diagnoses to PE in SCD patients, with the majority of diagnoses, such as pneumonia, already suggested by chest radiographs. The frequent incidental findings, most of which necessitate further evaluation, highlight the need for a cautious and tailored approach to using CTPA in the SCD population.

Abstract	Background: Coagulopathy is a well-recognized complication in patients with coronavirus disease 2019 (COVID-19). Pulmonary embolism (PE) has substantial morbidity and mortality if the diagnosis is missed or the management is delayed. Computed tomography pulmonary angiography (CT-PA) is the imaging modality of choice for PE. Therefore, this study aimed to investigate the positive rate of CT-PA for PE among patients with COVID-19. Methods: We conducted a retrospective study examining the diagnostic yield of CT-PA in patients with confirmed COVID-19 and compared it with that in patients without COVID-19. The study included all adult patients with confirmed COVID-19 who presented from June 2020 to June 2021. Results: The study included 316 patients, including 158 patients with COVID-19, who underwent CT-PA for ruling out PE. Overall, 76 patients were found to have PE on the CT-PA scan, yielding a positive rate of 24.1%, with a significant difference between patients with COVID-19 (8.2%) and those without COVID-19 (39.9%). Further, 138 (87.3%) patients with COVID-19 had elevated D-dimer levels compared with 34 (21.5%) patients without COVID-19. A multivariable regression analysis model revealed that the smoking status (odds ratio [OR] = 1.94; 95% confidence interval [CI]: 1.4-3.8) and obesity (OR = 4.1; 95% CI: 1.5-8.9) were independent predictors of PE among patients with COVID-19. However, the elevated D-dimer level was not significantly associated with PE among patients with COVID-19 (OR = 0.7; 95% CI: 0.4-1.8). Conclusion: The study found that the positive rate of CT-PA for PE was lower among patients with PE indicating probable overutilization of investigation in these patients. Additionally, patients with COVID-19 had a higher proportion of elevated D-dimer levels that may be a contributor to the increased investigation for PE. Lastly, patients with COVID-19 who were current smokers had a higher tendency of having PE.
