Abstract
A 57-year-old woman consulted our hospital because fluorodeoxyglucose-positron emission tomography showed abnormal accumulation in the spleen. An enhanced computed tomography scan showed a low-density mass (diameter, 10 mm) in the spleen. Magnetic resonance imaging showed a slight high-intensity mass on a T1-weighted image and a low-intensity mass on a T2-weighted image. We performed hand-assisted laparoscopic splenectomy because we suspected a malignant lymphoma or an inflammatory pseudotumor in the spleen. The resected spleen showed multiple yellow-white-colored nodules. The histological diagnosis was splenic sarcoidosis. There were no lesions in any other organs, including the lung, eyes, or skin. Herein, we report a rare case of splenic sacoidosis without extrasplenic lesions.
