Atypical Developmental Venous Anomaly Associated with Single Arteriovenous Fistula and Intracerebral Hemorrhage: a Case Demonstrated by Superselective Angiography

We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have been reported in the literature; however, we describe herein superselective angiographic findings in more detail and demonstrate the arteriovenous shunt more clearly than the previous reports. In addition, a literature review was performed to discuss the association of a developmental venous anomaly with vascular lesions.

Polypoid cystitis in an adult without history of catheterization

Polypoid cystitis is a benign exophytic mucosal lesion of the bladder. Differentiating it from papillary transitional cell carcinoma is difficult due to their similar characteristics. Although indwelling catheter is the main well-known cause of polypoid cystitis, some case reports unrelated to catheterization have been described. However, the radiological findings of polypoid cystitis have rarely been reported. We hereby describe polypoid cystitis in a 20-year-old man without a history of catheterization along with the computed tomographic findings

Sequential Magnetic Resonance Imaging Finding of Intramedullary Spinal Cord Abscess including Diffusion Weighted Image: a Case Report

Intramedullary spinal cord abscess (ISCA) is a rare infection of the central nervous system. We describe the magnetic resonance imaging (MRI) findings, including the diffusion-weighted imaging (DWI) findings, of ISCA in a 78-year-old man. The initial conventional MRI of the thoracic spine demonstrated a subtle enhancing nodule accompanied by significant edema. On the follow-up MRI after seven days, the nodule appeared as a ring-enhancing nodule. The non-enhancing central portion of the nodule appeared hyperintense on DWI with a decreased apparent diffusion coefficient (ADC) value on the ADC map. We performed myelotomy and surgical drainage, and thick, yellowish pus was drained.

Gastroduodenal Intussusception Caused by a Peutz-Jeghers Polyp in a Young Child: A Case Report

Gastroduodenal intussusception is a rare condition caused by the prolapse of a gastric tumor with subsequent invagination of a portion of the gastric wall into the duodenum. Various gastric lesions including adenoma, lipoma, leiomyoma, hamartoma, adenocarcinoma, gastrointestinal stromal tumor (GIST), and as in our case a Peutz-Jeghers polyp, can serve as a lead point of intussusception. Only three cases of gastroduodenal intussusception secondary to a Peutz-Jeghers polyp have been reported. We experienced a case of gastroduodenal intussusception in a 36-month-old boy who presented with intermittent nonbilious vomiting, abdominal pain, and anemia. An abdominal ultrasound and contrast enhanced CT scan showed gastrointestinal intussusception and a mass-like lesion in the second portion of duodenum. A laparotomy revealed a 7x8 cm sized mass at the gastric body, which was pathologically confirmed as a Peutz-Jeghers polyp.
