Congenital absence of the portal vein is a rare anomaly in which diverse types of congenital portosystemic shunts are present. In this report, we describe this rare anomaly of a portosystemic shunt between the inferior mesenteric vein and left internal iliac vein, in a middle-aged man presenting with portosystemic encephalopathy.

A tailgut cyst is a rare congenital abnormality located in the retrorectal space and is usually manifested during childhood or adulthood. We report the MR, CT and ultrasound findings of a tailgut cyst in a 23-day-old neonate.

PURPOSE: We wanted to evaluate the usefulness of MDCT for localizing a bleeding site and for helping make a decision on further management for acute intestinal bleeding. MATERIALS AND METHODS: We conducted a retrospective review of 17 consecutive patients who presented with acute intestinal bleeding and who also underwent MDCT before angiography or surgery. The sensitivity of MDCT for detecting acute intestinal bleeding was assessed and compared with that of conventional angiography. RESULTS: The sensitivity of MDCT for the detection of acute intestinal bleeding was 77% (13 of 17), whereas that of angiography was 46% (6 of 13). All the bleeding points that were subsequently detected on angiography were visualized on MDCT. In three cases, the bleeding focus was detected on MDCT and not on angiography. In four cases, both MDCT and angiogphy did not detect the bleeding focus; for one of these cases, CT during SMA angiography was performed and this detected the active bleeding site. CONCLUSION: In patients with acute intestinal bleeding, MDCT is a useful image modality to detect the bleeding site and to help decide on further management before performing angiography or surgery. When tumorous lesions are detected, invasive angiography can be omitted.

Anticoagulation with heparin has been the standard management therapy of deep vein thrombosis during pregnancy. Pregnancy is generally considered as a contraindication for thrombolysis. However, anticoagulation therapy alone does not protect the limbs from post-thrombotic syndrome and venous valve insufficiency. Catheter-directed thrombolysis, combined with angioplasty and stenting, can remove the thrombus and restore patency of the veins, resulting in prevention of post-thrombotic syndrome and valve insufficiency. We report successful catheter-directed thrombolysis and stenting in two early gestation patients with a deep vein thrombosis of the left lower extremity.

A ciliated hepatic foregut cyst (CHFC) is a rare cystic lesion consisting of a ciliated pseudostratified columnar epithelium, subepithelial connective tissue, a smooth muscle layer, and an outer fibrous capsule. A CHFC is usually unilocular and occurs at a higher frequency in males. A predilection exists at the medial segment located at the left lobe of the liver. We report the first case of a ciliated hepatic foregut cyst mimicking hepatic metastasis on a CT scan of a patient concurrently afflicted with gastric cancer.

PURPOSE: The primary goal of this study was to evaluate the MR findings of systemic lupus erythematosus (SLE) patients with neuropsychiatric symptoms. MATERIALS AND METHODS: The MR images of 38 patients with SLE were evaluated based on the presence of the following abnormal lesions: the locations of the abnormal signal intensity lesions in the white matter, infarctions, a small vessel vasculopathy, leukoencephalopathy, hemorrhage, abscess, and other lesions. RESULTS: The MR images showed an abnormality in 22 of 38 (58%) episodes. Abnormal signal intensities were noted in the subcortical and periventricular white matter in six cases, acute territorial infarctions in five cases, multiple small acute embolic infarctions in four cases and a brain abscess in two cases. A reversible posterior leukoencephalopathy was found in one case. In addition, another patient had vasogenic edema with focal central cytotoxic edema at the pons. The entire cerebral and corpus callosum volumes were significantly smaller in four patients with SLE as compared to the volumes in healthy control subjects. CONCLUSION: SLE may induce variable MR imaging findings of the CNS. Recognition of the variable findings is helpful for easy diagnosis and prompt treatment.

A fibromatosis or desmoid tumor of the breast is an extremely rare benign tumor, which is often presented clinically and radiologically as a malignant tumor. Although benign, fibromatosis or desmoid tumors can grow aggressively in local infiltrating patterns. The recurrence is relatively common; hence a wide excision with a clear margin around the tumor is necessary. We report a case of a young female patient with a recurring fibromatosis of the breast after a local excision.

Esophageal squamous cell papillomatosis is a rare disorder that is usually found incidentally on an upper gastrointestinal endoscopy examination or autopsy. A 70-year-old woman presented with a two-month history of dysphagia and abdominal discomfort. A chest CT scan showed diffuse marked thickening of the esophageal wall along the entire length and multiple small enhancing polypoid projections in the distal esophagus. Diffuse circumferential FDG uptake in the entire esophagus was seen on [18F] FDG PET/CT. Squamous papillomatosis was diagnosed by an endoscopic biopsy. We report a case of extensive esophageal papillomatosis with imaging features on CT and [18F] FDG PET/CT, with a review of the clinical literature.
