Abstract	Objective: Several studies in the literature have used contrast-enhanced magnetic resonance imaging to investigate arachnoid granulations protruding into the cranial dural sinuses. The current study aimed to investigate the protrusion of arachnoid granulations into the superior sagittal sinus, transverse sinus, straight sinus, and confluence of sinuses and determine the frequency of brain herniation into giant arachnoid granulations using contrast-enhanced 3-dimensional T1-weighted magnetic resonance imaging. Materials and methods: Images of 550 patients with intra-sinus arachnoid granulations who underwent contrast-enhanced 3-dimensional T1-weighted thin-slice magnetic resonance imaging were retrospectively re-evaluated. Only 300 patients with at least 1 intra-sinus arachnoid granulation were included in the study. The protrusion of arachnoid granulations into superior sagittal sinus, transverse sinus, straight sinus, and confluence of sinuses was investigated. In addition, large arachnoid granulations and brain herniations into arachnoid granulations were also noted. Results: A total of 889 focal filling defects of arachnoid granulations, at least 1 in the dural sinus, were detected. Of the filling defects of arachnoid granulations, 183 were in the right transverse sinus, 222 in the left transverse sinus, 265 in superior sagittal sinus, 185 in straight sinus, and 34 in confluence of sinuses. Brain herniation into arachnoid granulations was detected in 8 (2.7%) of the patients included in the study. All the filling defects detected in the dural sinuses on post-contrast 3-dimensional T1-weighted images were isointense with cerebrospinal fluid and had round, oval, or lobulated contours. A positive weak correla- tion was found between patient age and the size and number of arachnoid granulations (r = 0.181, P < .01 and r=0.207, P < .001, respectively). It was observed that the size and number of arachnoid granulations increased as the age of the patients increased. Conclusions: The distribution, shape, number, and size of intra-sinus arachnoid granulations can vary considerably. Brain herniation into arachnoid granulation can also be seen. Three-dimensional cranial magnetic resonance imaging sequences can be safely used in the evaluation of arachnoid granulations.

Abstract	Objective: During COVID-19 vaccine development studies, vaccines' efficacy and safety profiles should be carefully investigated. Only a few studies have shown that the COVID-19 vaccine can cause axillary lymphadenopathy on the injection arm. This study aimed to investigate the incidence of axillary lymphadenopathy and imaging findings using B-mode and Doppler ultrasonography (US) examinations in volunteers who had recently been vaccinated against COVID-19. Methods: The ipsilateral and contralateral axillae of 101 volunteers who received the COVID-19 vaccine were evaluated using B-mode and Doppler US examinations. The volunteers were asked when and to which arm the vaccine had been applied, and the type and dose of the vaccine were recorded. It was also questioned whether the individual experienced any side effects after vaccination, such as pain, tenderness, fever, and redness at the injection site. In addition, the demographic data of the participants, such as age and gender, were recorded. Results: The B-mode US examinations revealed that the long- and short-axis diameters, size, cortical thickness, and asymmetric cortical thickening of the left axillary lymph nodes were significantly higher compared to the right side in individuals having received the CoronaVac vaccine (p<0.05). When the individuals were evaluated separately according to gender, the frequency of cortical thickness and asymmetric cortical thickening in the left axillary lymph nodes was higher than on the right side in both males and females (p=0.011). Conclusion: It should be kept in mind that ipsilateral reactive lymphadenopathy may develop after the COVID-19 vaccine. This knowledge can prevent unnecessary axillary lymph node biopsies.

Abstract	In this study, we present the ultrasound imaging features of lymph nodes arising in the regional lymph node chain after the first or second dose of the Pfizer-BioNTech COVID-19 vaccine. Ipsilateral lymphadenopathy adjacent to the vaccine injection site is an extremely rare but expected adverse reaction following COVID-19 vaccination. Although axillary lymphadenopathy is more common, cases of supraclavicular lymphadenopathy have also been reported after widespread vaccination against COVID-19. Ultrasonography examinations were performed on seven patients with no previous pathological conditions, who presented to our radiology department after receiving the Pfizer-BioNTech COVID-19 vaccine. Bilateral axillary, supraclavicular and subclavicular lymph node stations were explored. These patients typically present with enlarged hypoechoic lymph nodes with the loss of fatty hilum, asymmetric or diffuse cortical thickening, and increased hilar and cortical vascularization on the color doppler ultrasonography of the ipsilateral axillary and supraclavicular regions. Radiologists and clinicians should be aware of the ultrasonographic features of these lymph nodes and should inform the patient that these lymph nodes are often a self-limiting process. Thus, unnecessary axillary lymph node biopsies should be avoided, and patients should be treated conservatively.

Abstract	Tenosynovial giant cell tumor (TSDHT) is a slow-growing benign tumor arising from the tendon sheath or bursa. TSDHT of the foot and foot ankle has been reported much less frequently compared to the hand and knee. Morphologically it is classified as the localized form, often seen in the hand, and the diffuse form seen in large joints. Therefore, TSGCT should be considered in the differential diagnosis of the foot and ankle soft tissue tumors. Clinical and radiological findings of the intra-articular localized form of TSGCT in the ankle were presented in this study.

Abstract	Aim: To explain the association between vertebral body hypoplasia and degenerative changes in the discovertebral complex and facet joints, and to assess the incidence of hypoplasia of the vertebral body at the L5 level. Material and methods: A retrospective analysis was made of 3,100 patients aged 20?50 years who underwent lumbar MRI with a complaint of back pain, of which 55 were identified with vertebral body hypoplasia. Intervertebral disc degeneration was evaluated in the study using the Pfirrmann and Modified Pfirrmann classification systems, while degenerative changes in the vertebrae endplate were assessed using the Modic classification system. Osteoarthritis of the facet joint was graded at the L4-5 level, and spondylolysis and spondylolisthesis rates were compared between the control group and the hypoplasic group. Results: The incidence of hypoplasia of the vertebral body at the L5 level was found to be 1.8% in the population with back pain in the 20?50-year age group. In the hypoplasia group, disc degeneration was detected at a higher rate than in the control group (p < 0.001). The distribution of Modic signal changes in the superior and inferior endplates of the vertebrae differed significantly between the hypoplasia and control groups (p < 0.001).The rate of spondylolysis was 7.7% in the control group and 65.5% in the hypoplasia group (p < 0.001), and spondylolisthesis was significantly more common in the hypoplasia group (18.4%, p < 0.001). In addition, facet joint degeneration was identified more frequently in the hypoplasia group. Degenerative findings were detected in 74.5% of the right posterior intervertebral joints, and in 70.9% of the left posterior intervertebral joints in the hypoplasia group. Conclusion: Vertebral body hypoplasia is a predisposing factor for disc degeneration, facet osteoarthritis and degeneration in the vertebral endplates, and has also been associated with spondylolysis and spondylolisthesis.

Abstract	Objective: To determine the morphological features and apparent diffusion coefficient (ADC) values of normal intraparotid lymph nodes (IPLNs) obtained from the MRI examination. Study design: Cross-sectional descriptive study. Place and duration of study: Health Sciences University, Diskapi Yildirim Beyazit Training and Research Hospital, Department of Radiology, Ankara, Turkey, from January 2018 to December 2021. Methodology: The study included 232 patients who underwent neck MRI examination. The long axis diameter (LAD) was measured as the largest diameter of the IPLN, and the short axis diameter (SAD) was measured perpendicular to the LAD. ADC measurements were undertaken by placing the largest region of interest suitable for the size of the IPLNs. Results: A total of 394 lymph nodes were evaluated. The median LAD and SAD of the lymph nodes were 5.50 (2.50) mm and 3.50 (2.00) mm, respectively. The LAD was 9 mm or lower in 95.7% of the lymph nodes; the SAD was 6 mm or lower in 94.7%. The ADC map was evaluated in 275 IPLNs, with the median ADC value being calculated as 0.77(0.18)x10-3 mm2/s. The ADC value was 1.05x10-3 mm2/s or lower in 96.3% of the lymph nodes. Conclusion: A SAD of 6 mm; and a LAD of 9 mm could be used as normalcy criteria in IPLNs. Normal IPLNs may have an ADC of 1.05x10-3 mm2/s or lower. Considering that benign IPLNs may have low ADC values, those can prevent false-positive results in terms of malignancy. Key words: Parotid glands, Lymph nodes, Magnetic resonance imaging, Apparent diffusion coefficient.

Abstract	Reactions at the vaccine injection site are usually mild and transient. Musculoskeletal symptoms, such as myalgia and arthralgia, are commonly seen following vaccination. Shoulder injury related to vaccine administration (SIRVA), defined as shoulder pain and limited range of motion in the shoulder after intramuscular vaccine administration into the upper arm, may occur due to incorrect vaccine administration. Using the appropriate injection technique in the intramuscular administration of vaccines will reduce the risk of SIRVA. In this paper, we report the clinical and magnetic resonance imaging findings of a 26-year-old female patient presenting with SIRVA after rabies vaccination and discuss this case in light of the current literature.

Abstract	Fibrolipomatous hamartoma of the nerve is a rare, benign, and congenital peripheral nerve tumor. A case with symptoms of carpal tunnel syndrome due to median nerve fibrolipoma were presented. The patient was a 31 years old male and his right side was affected. There was numbness in the 1st, 2nd and 3rd fingers and radial side of the 4th finger, pain awakening from sleep at night, and thenar atrophy. His complaints have been present for four years and have progressed in the last six months. Electromyography, right hand ultrasonography and magnetic resonance imaging (MRI) were performed on the patient. In the hand MRI, a lesion involving the median nerve and giving a cable appearance was observed at the wrist level. During the operation, the median nerve was relaxed throughout the mass and some of the fatty tissue around the nerve was excised. Biopsy findings were compatible with fibrolipomatous hamartoma.

Abstract	Patients with traumatic intracranial subarachnoid hemorrhage (SAH) rarely develop spinal subarachnoid hemorrhage (SSAH) without direct spinal injury. We present the case of a 76-yearold male patient with traumatic intracranial SAH and subdural hematoma, back pain and weakness in the both lower limbs radiating to the legs three days after the trauma. After worsening of pain and numbness, the patient underwent a lumbar magnetic resonance imaging 7 days after the trauma, in which blood was seen in the spinal canal in the lumbosacral region. The bleeding was considered SSAH because of the liquid level. The patient underwent conservative treatment because the patient was found to be at high cardiac risk and the neurological deficit was mild. In patients with traumatic intracranial hemorrhage and delayed pain or neurological deficits, SSAH should be suspected in the first period of trauma.
