    Abstract Following the initial liver biopsy attempts, several techniques using a wide range of methodologies and materials were developed. Many studies on the evaluation of post-liver biopsy complications were conducted. However, their fundamental limitation was significant variance in patient demographics and methodology, which might account for the inconsistent outcomes. Therefore, a uniform methodology to perform percutaneous liver biopsies that result in comparable outcomes around the world is required. This study aimed to determine the precise complication rate following percutaneous liver biopsy using a consistent method in all individuals. It also aimed to establish a consistent operating procedure for a percutaneous liver biopsy that yielded comparable outcomes. Between July 2018 and July 2019, 116 patients were enrolled in this retrospective study for percutaneous liver biopsy. All individuals underwent a biopsy using the same procedure. There was an attempt to exclude elements that could have an impact on the complication rate. For this purpose, the same type and size of needle were utilized. Moreover, a single needle pass, a subcostal approach, deep inspiration breath holding, identical pre- and post-biopsy preparation, real-time ultrasonography guidance, the use of a single operator, and the absence of sedation or general anesthesia were the other approaches that were used to minimize the impact of variables that could raise complication rates. The overall complication rate was 19.8%, of which 18.9% of patients experienced pain and mild bleeding, and one patient (0.9%) experienced hematoma necessitating precautionary hospitalization. The overall percentage of patients who experienced pain was 13.8%. No further complications were observed. The findings of this study could provide an accurate estimate of the post-liver biopsy complication rate. Furthermore, due to a lower complication rate than other practiced procedures, this uniform methodology could be an attractive alternative in clinical practice. However, more research is required to confirm these results.

    Abstract Background: Anatomic variations of the cystic duct (CD) are commonly encountered. Being aware of these variants will reduce complications subsequent to surgical, endoscopic, or percutaneous procedures. Magnetic resonance cholangiopancreatography (MRCP) is the least invasive and the most reliable modality for biliary anatomy surveys. This study aimed to determine the prevalence of cystic duct variations in the Iranian population.
    Methods: In this retrospective cross-sectional study, MRCP images of 350 patients referred to Shiraz Faraparto Medical Imaging and Interventional Radiology Center from October 2017 to October 2018 were reviewed. The CD course and insertion site to the extrahepatic bile duct (EHBD) was determined and documented in 290 cases. Descriptive statistics and Chi square test were applied for data analysis via SPSS software.
    Results: About 77% of cases revealed the classic right lateral insertion to the middle third of EHBD. The insertion of CD to the upper third and the right hepatic duct was 10%, and the insertion to the medial aspect of the middle third of EHBD from anterior or posterior was noted to be about 7.6%. From 2.8% of insertions to the lower third, 1% demonstrated parallel course, and finally, 0.3% of cases presented short CD.
    Conclusion: CD variations are relatively common, and MRCP mapping prior to the hepatobiliary interventions could prevent unexpected consequences.

    Abstract Background: Several typical and atypical findings have been observed in Covid-19 high-resolution computer tomography (HRCT). To our knowledge, there is no study investigating the relationship between the presence of nodules in Covid-19 patients and the patient's condition. Therefore, the present study assessed the frequency of pulmonary nodules in Covid-19 patients according to their condition. Methods: This cross-sectional study assessed the medical images of the patients referred to three university-affiliated centers (Nemazi, Ali Asghar and Shahid Faghihi Hospital) to perform Covid-19 HRCT from April to September 2020. The centers have been named H1, H2, and H3. Patients who were referred to these centers had good, poor, and fair conditions, respectively. The history of patients was assessed carefully. Patients' demographic information, nodule shape, number, size, location, presence of cavitation, and GGO around the nodule were assessed and recorded. Results: Overall, 20576 patients (mean age=46.75±16.64 years old) were included in the study. Only 2.1% of cases had solid nodules. Most of them (96.76%) were accompanied by a GGO (halo sign), and only 10.42% were associated with a cavity. The good condition, patients showed significantly more solid nodules (3.46%) than others. In size of the nodules in good-condition patients (1.8 cm) is significantly larger than in fair-condition (1.22 cm) or poor condition patients (1.15 cm). 79.86%, 12.5%, and 7.64% of nodules were multiple, dual/triple, and single, respectively. Conclusion: The frequency of nodules in the HRCTs of good-condition patients was significantly higher than in fair- or poor-conditionpatients; they also had more multiple and larger-sized nodules. The Pearson-coefficient test also revealed a small negative correlation between the presence of nodules and the patient's condition. It seems the presence of nodules indicates higher immunity to viral infections. In the follow-up, it was revealed that people who had nodules were not hospitalized in the ICU. ...

    Abstract Bronchopleural fistula (BPF), a sinus tract between the bronchial system and the pleural space, is associated with COVID-19 and can lead to pneumothorax, which increases the mortality rate. Due to the analytical status of COVID-19 patients, sealing the BPF necessitates the least minimal invasive treatment. Herein, we demonstrated a technique of sealing post-COVID-19 BPF with direct injection of cyanoacrylate glue under the guidance of a computed tomography scan. Following glue injection, the BPF was completely sealed in all four patients. In conclusion, in COVID-19 patients with small and distal BPF, percutaneous glue injection is recommended for BPF closure.

    Abstract Background: Osteoid osteoma is a painful benign osteoblastic lesion occurring mainly in the long bones. On the one hand, some studies have declared that post-treatment CT cannot determine the success or failure of radiofrequency ablation, on the other hand, some studies have stated that imaging follow-up can be helpful or even mandatory in some cases. The present study aims to evaluate Osteoid Osteoma's imaging features before or after radiofrequency ablation with or without curettage and during the follow-up period. Methods: In this retrospective and cross-sectional study, we reviewed twenty seven Osteoid Osteoma patients with radiofrequency ablation who were assessed via drilling with or without curettage from March 2015 to December 2019 at Nemazi Hospital, Shiraz University of Medical Sciences. Results: Radiofrequency ablation with drilling was used in 22(81.5%) patients, and for the rest 5(18.5%), radiofrequency ablation with curettage and drilling was performed as a treatment procedure. The overall clinical success rate was 92.6%(25/27), with a low complication rate (7.4%). The mean diameter of nidus in pre/pos treatment was 3.46±2.02 and 2.22±1.75 mm, respectively. Femur 12(44.4%) was the most common bone in the patients. Significant differences between pre/post treatment follow up examinations in nidus size (P=0.03), nidus diameter (P=0.02), bone and calcification size (P=0.005) were detected. Additionally, it depicts that the mean values of tumor size and cortical thickening decreased after treatment. Conclusion: It is noteworthy that the present study had some limitations, including the small sample size and the relatively short follow-up period. There is no significant difference between radiofrequency ablation after drilling and curettage in treating Osteoid Osteoma. It is concluded that although there was a significant difference in pre/post-treatment imaging, there is no need for continuous imaging follow-up in treated patients without clinical complications such as pain to mitigate radiation dose ...

    Abstract Background: Carbapenem-resistant Klebsiella pneumoniae (CRKP) infections are a major public health problem, necessitating the administration of polymyxin E (colistin) as a last-line antibiotic. Meanwhile, the mortality rate associated with colistin-resistant K. pneumoniae infections is seriously increasing. On the other hand, importance of administration of carbapenems in promoting colistin resistance in K. pneumoniae is unknown.
    Case presentation: We report a case of K. pneumoniae-related pyogenic liver abscess in which susceptible K. pneumoniae transformed into carbapenem- and colistin-resistant K. pneumoniae during treatment with imipenem. The case of pyogenic liver abscess was a 50-year-old man with diabetes and liver transplant who was admitted to Abu Ali Sina Hospital in Shiraz. The K. pneumoniae isolate responsible for community-acquired pyogenic liver abscess was isolated and identified. The K. pneumoniae isolate was sensitive to all tested antibiotics except ampicillin in the antimicrobial susceptibility test and was identified as a non-K1/K2 classical K. pneumoniae (cKp) strain. Multilocus sequence typing (MLST) identified the isolate as sequence type 54 (ST54). Based on the patient's request, he was discharged to continue treatment at another center. After two months, he was readmitted due to fever and progressive constitutional symptoms. During treatment with imipenem, the strain acquired bla
    Conclusions: Based on this information, can we have a theoretical hypothesis that imipenem is a promoter of resistance to carbapenems and colistin in K. pneumoniae? This needs more attention.

    Abstract Background: Different treatments are available for aggressive vertebral hemangioma [AVH], but a consensus is yet to be reached about the best therapeutic approach.
    Purpose: To explore the possibility that selecting a less aggressive therapeutic approach for AVH decreases the intraoperative and postoperative complications while providing similar clinical, radiographic, and disease-free survival results to more aggressive therapeutic methods.
    Study: We report the case of an AVH of the thoracic spine at the T5 level, treated via perioperative selective arterial embolization plus surgical decompression via laminectomy and reconstruction with polymethylmethacrylate (PMMA) vertebroplasty.
    Patient: The patient was a 17-year-old male referred to our center with the chief complaint of low back pain from two months earlier, without any response to analgesics, and with neurologic manifestations as paraparesis (one month) and progressive sphincter problems (one week). Upon imaging, the impression was an aggressive spinal tumor with cord compression.
    Outcome measures: After the operation, the patient's pain immediately improved, and his neurologic manifestations progressively improved.
    Results: The patient started walking with help about three weeks after the operation. Roughly six months later, he achieved a complete neurological recovery. At present, about two years following the operation, he has a normal life without any neurological problems.
    Conclusion: Based on our experience with AVH, the selection of less aggressive therapeutic approaches such as perioperative diagnostic angiography and selective embolization decrease the intraoperative and postoperative complications like intraoperative bleeding and neurological injury, while achieving similar clinical, radiographic, and disease-free survival outcomes to more aggressive therapeutic methods.
