[A suspicious case of metastasis to the stomach from primary lung cancer; report of a case].

A 82-year-old man consulted for therapy for lung cancer in March 2010. Chest computed tomography (CT) showed a mass in right lower lobe of the lung. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed the accumulation in the mass. Lung cancer was strongly suspected and anticancer chemotherapy was started. The patient complained of difficulty in swallowing in August 2011. Gastroendoscopy revealed a submucosal mass in the gastric corpus. The specimen from the mass showed gastric metastasis from lung cancer on pathological study. The case of gastric metastasis from lung cancer is rare. When we concern the patient of lung cancer, it should be considered gastric metastasis.

Sclerosing stromal tumor of the ovary with atypical magnetic resonance imaging findings in a middle-aged woman.

We encountered a case of atypical sclerosing stromal tumor of the ovary (SST) in a middle-aged woman. This 52-year-old woman presented with a 2-year history of abdominal distention. Magnetic resonance imaging (MRI) showed a large mass extending from the pelvis to the epigastrium. T2-weighted MRI showed an island-shaped area of slight hyperintensity. Dynamic MRI demonstrated gradual light enhancement of the area in which T2-weighted imaging showed low intensity. The diagnosis of the tumor proved difficult because neither MRI findings nor the age of getting sick were atypical. We report this case with MRI findings and correlated pathology.
