Bowel Obstruction due to Shiitake Mushrooms: Diagnostic Features on Computed Tomography.
Shiitake mushrooms are edible mushrooms popular in East Asian cuisine. We herein report a 69-year-old man with abdominal distension and vomiting after ingesting several pieces of sautéed Shiitake mushrooms. ⋯ After conservative treatment, he passed four pieces of Shiitake mushrooms. Despite the rarity, the condition can be diagnosed before exploratory surgery by careful and detailed interpretation of CT findings.

A 79-year-old woman was evaluated for weakness, dysphagia, and elevated levels of creatinine kinase. Her medical history included stage IIIB cervical cancer eight years previously, which improved after undergoing radiotherapy. Two years later, cancer recurred in the right hilar and mediastinal lymph nodes, and the patient was successfully treated with chemotherapy. ⋯ Computed tomography revealed left supraclavicular lymphadenopathy, compatible with cancer recurrence. Anti-nuclear matrix protein 2 (NXP2) antibody was found in her sera and a diagnosis of cancer-associated dermatomyositis was thus made. This case suggests that cancer progression over a period of years may have triggered the onset of autoimmunity against NXP2.

To our knowledge, there have been no reports of right-sided infective endocarditis (RSIE) with ventricular free wall vegetation caused by Abiotrophia defectiva. We herein report a case of RSIE caused by A. defectiva with ventricular free wall vegetation in a 27-year-old man with ventricular septal defect (VSD). Computed tomography showed multiple bilateral pulmonary nodular shadows. ⋯ Blood culture revealed A. defectiva. These findings are consistent with a diagnosis of infective endocarditis and septic pulmonary embolism. Treatment with ceftriaxone and gentamicin and subsequent surgical VSD closure improved the patient's condition without recurrence.
