ABSTRACT
A man in his 40s visited our hospital with a chief complaint of upper abdominal pain after defecation. His general and local conditions were good. Intraperitoneal free air was detected on an abdominal computed tomography (CT) scan, and laboratory tests revealed leukocytosis. Esophagogastroduodenoscopy showed no abnormalities. Emergent laparotomy was performed because of the suspected intestinal perforation, but neither perforation nor peritonitis was observed. Bacterial culture of intraperitoneal lavage fluid was negative. The postoperative course was uneventful and he was discharged. Because the cause of pneumoperitoneum was unknown, the diagnosis was idiopathic pneumoperitoneum. However, we had the opportunity to evaluate abdominal CT images taken with the lung window setting 4 years before the operation, which showed pneumatosis intestinalis in the ileocecal region. It has been reported that metachronous pneumatosis intestinalis is sometimes detected in cases of pneumoperitoneum with pneumatosis intestinalis. Thus, pneumatosis intestinalis was suspected as the cause of pneumoperitoneum in this case.
ABSTRACT
Scrotal hematocele is defined as retention of blood in the tunica vaginalis. Although it is usually an acute change, it can also have a chronic course. A 55-year-old man was being treated for hypertension and diabetes in the Department of Internal Medicine at our hospital. He visited the hospital’s Department of Urology because 3 months earlier he had noticed enlargement of the right scrotum without trauma to the perineum. The right scrotum was swollen to the size of a small child’s head. Imaging examination showed no testicular tumor. Puncture yielded 550 ml of bloody fluid. Surgery was performed to find and treat the source of bleeding. The tunica vaginalis was highly irregular and thickened. Considering the possibility of mesothelioma or other malignancy, we removed the testis after transection of the spermatic cord as proximally as possible. The histopathological diagnosis was encapsulated hematoma with cholesterin granuloma, which was diagnosed as chronic scrotal hematocele.
