A 76-year-old woman with advanced pancreatic cancer developed recurrent cholecystitis after covered self-expandable metal stent (CSEMS) placement. The cholecystitis was refractory to repeated percutaneous transhepatic gallbladder drainage (PTGBD). ⋯ We were able to manage the cholecystitis by ETGBD without further recurrence. ETGBD is considered an effective internal drainage method for the management of acute cholecystitis after CSEMS placement, and its indication may be decided on the basis of the findings of cholecystography through the PTGBD route.

A 77-year-old man presented with abdominal pain for 1 week. He was taking enteric-coated low-dose aspirin (LDA) to prevent secondary cardiovascular events and a proton pump inhibitor (PPI). Computed tomography indicated a small intestinal perforation; thus, small intestine resection was performed. ⋯ He has experienced no further recurrence since then. This is the first case of small intestinal perforation caused by enteric-coated LDA. Enteric-coated LDA may cause small intestinal perforation in patients with severe atherosclerosis under PPI administration.

We herein report a case of pulmonary veno-occlusive disease (PVOD) induced by allo-hematopoietic stem cell transplantation (HSCT) in a 48-year-old man who was diagnosed with acute myeloid leukemia. Five months after transplantation, he developed dyspnea and was diagnosed with pulmonary hypertension based on right heart catheterization. ⋯ Based on the clinical course, hypoxemia, diffusion impairment, and computed tomography findings, the patient was diagnosed with HSCT-related PVOD. Critical attention should be paid to dyspnea after HSCT for the early diagnosis of PVOD.

Objective High-quality images can be obtained with 320-slice computed tomography (CT) with model-based iterative reconstruction (MBIR). We therefore investigated the diagnostic accuracy of 320-slice CT with MBIR for detecting significant coronary artery stenosis. Methods This was a retrospective study of 160 patients who underwent coronary CT and invasive coronary angiography (ICA). ⋯ No significant differences were observed between the two groups in the patient- and segment-based analyses. However, among cases with a severe coronary artery calcium score >400 (31 cases in Group 1 and 28 in Group 2), the specificity and overall accuracy were significantly higher (all p<0.01) in Group 2 than in Group 1 according to the segment-based analysis. Conclusion The diagnostic accuracy of the detection of coronary artery stenosis on CT was improved using 320-slice CT with MBIR.

A 74-year-old woman presented with left lateral abdominal pain. Abdominal echography revealed left hydronephrosis and a pelvic mass. ⋯ The most common histological types of ovarian lymphoma are diffuse large B-cell lymphoma and Burkitt lymphoma, with FL being an extremely rare variant. We herein report a case of ovarian FL diagnosed as hydronephrosis.
