Atrial septal defects of a single Secundum with favorable anatomy and margins are commonly treated with septal occluder devices. Device embolization is a well-known rare and serious complication of transcatheter structural heart interventions. Percutaneous transcatheter closure under fluoroscopic guidance using the occluder device has been considered as a safe and effective alternative to open surgery with a higher technical success rate. However, and in selected cases it can be managed conservatively. In the current study we reported out local experience in the conservative non-surgical management of a patient presented with asymptomatic lately migrating and embolized amplatzer atrial septal defect occluder device into the supraceliac abdominal aorta. This conservative management was adopted after failure of the multiple trials of the endovascular retrieval of the embolized device. However, the procedure was terminated to keep away from any local vascular complications. The patient was followed up for more three years with serial computed tomography angiography on a scheduled outpatient basis. In the current study, we reported and sharing our local experiences for the non-operative, conservative management of a dislocated and embolized atrial septal defect occluder device to the supraceliac abdominal aorta.Gastric volvulus is an uncommon disorder with an unknown incidence, unless it stays in the back of the diagnostician's mind, diagnosis of gastric volvulus, which can have significant morbidity and mortality associated with it, can be easily missed and can present either in the acute or chronic setting with variable symptoms. When it occurs in the acute scenario, patients present with severe epigastric pain and retching without vomiting. Together with inability to pass nasogastric tube, they constitute Borchardt's triad. The presence of a hiatal hernia with persistent vomiting despite initial antiemetic treatment should trigger one to think of gastric volvulus, despite the patient appearing very stable. We report a case which presented in our hospital with abdominal pain and vomiting. As Oesophagogastroduodenoscopy shows hiatal hernia and peptic ulcer. Primary gastric volvulus occurs in the absence of any defect in the diaphragm or adjacent organ pathology and may be caused by weakening of gastric supports. As conclusion; Gastric volvulus is a surgical case, requiring early diagnosis and aggressive management, as a delay results into complications like gangrene and perforation which substantially increase the morbidity and mortality in these patients, and contrast enhanced computed tomography (CECT) is the best modality for diagnosis of gastric volvulus.Proliferative myositis is a rre benign pseudosarcomatous inflammatory process that rapidly grows in muscles. Its clinical and radiological features may, however, simulate a malignant tumor. We report ultrasound and MRI appearances of a 63 years-old woman with no significant anterior pathological history presented to our radiology department with two weeks history of a painful mass in the left musculus latissimus dorsi, increasing progressively in size, without history of recent trauma. This study describes the imaging features of these pseudo inflammatory process, which may help to suggest the diagnosis, but the imaging finding are variable and nonspecific. However, histopathological examination is usually recommended to confirm the diagnosis. In our case, the final diagnosis was proved by ultrasound-guided biopsy. We also review the imaging features of this entity in the current literature.Sebaceous carcinoma is a rare, malignant tumor of the sebaceous glands. This is a case report of a 75-year-old man who presented with a right lower axillary mass which initially was considered to be a benign sebaceous cyst from sonography. The lesion rapidly changed in clinical and sonographic appearances and on histology was a sebaceous carcinoma. This unusual tumor accounts for less than 1% of all cutaneous malignant tumors, and the chest wall is a rare extraocular site with only nine cases described in the literature. Immunohistochemistry was negative for MSH2 and MSH6, and positive for MLH1 and PMS2, raising the possibility of Lynch or Muir-Torre Syndrome which is a known association with this rare tumor.Mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is one of the most common maternally inherited mitochondrial disorders, with no specific treatment available. We report a case of a 34-year-old female in whom symptoms of MELAS were initially misdiagnosed as herpes simplex encephalitis (HSE). Her clinical course was marked by an acute episode of consciousness disturbance with newly developed lesions on brain MRI five years after disease onset and followed by progressive sensorineural hearing loss. Brain imaging sequences throughout the seven years of her illness are presented. The final diagnosis of MELAS syndrome was confirmed by m.3243A>G mitochondrial mutation. In conclusion, understanding the overlapping imaging features between MELAS syndrome and other mimickers, such as HSE or ischemic stroke, is crucial to help establish early diagnosis and initiate appropriate treatment.An ectopic pregnancy carries the potential for disastrous maternal complications. Ziritaxestat in vivo Early first trimester pelvic ultrasound examinations are frequently obtained in cases of pelvic pain and vaginal bleeding to assess for such diagnoses. The "bagel sign" and the "blob sign" described two sonographic appearances of tubal ectopic pregnancy with positive predictive values of > 95%. Current ectopic pregnancy consensus statements differ in the interpretation of these findings; however, radiologists should have familiarity with the appearances of these findings so as to best educate ordering providers on the potential for presence of a tubal ectopic pregnancy and need for very close patient surveillance.Paragangliomas are rare neuroendocrine tumors arising from paraganglion cells in sympathetic or parasympathetic chains, which may develop in the abdomen, chest, skull base, and neck. As paragangliomas have a wide range of imaging features, the diagnosis often requires tissue sampling. We present a unique case of a paraganglioma which originally presented as a rib tumor. A 64-year-old male with right flank pain for 2 months' was referred for a noncontrast renal colic CT. He was found to have a 3.7 × 3.5 cm soft tissue mass invading the left posterior 9th rib and paraspinal muscle. This was fluorodeoxyglucose F 18, (18F-FDG) avid, with no other distant metabolic activity. He underwent ultrasound-guided core biopsy which revealed a diagnosis of paraganglioma. A right thoracotomy with chest wall resection of 8, 9, and 10 ribs were subsequently performed. The tumor was removed along with a small portion of adherent lung. The tumor was positive for CD56, synaptophysin and chromogranin. S-100 highlighted occasional sustentacular cells, consistent with a pathologic diagnosis of a paraganglioma.
