title: [Idiopathic adrenal hematoma: a case report].
abstract: We report a rare case of idiopathic adrenal hematoma. Including our case, 13 such cases have been described in Japan. A 63-year-old [correction of 65] woman was admitted to our hospital for further examination of a right adrenal mass on ultrasonography. Laboratory tests including hormonal assay were within the normal ranges. Computed tomography showed a tumor with calcification measuring 3.0 x 2.0 cm in the right adrenal gland. Magnetic resonance imaging (MRI) revealed a mass with heterogeneous low to iso signal intensity on T1-weighted images and high signal intensity on T2-weighted images. A peripheral rim of the mass was slightly enhanced on dynamic MRI. The patient underwent laparoscopic adrenalectomy. Histopathological examination revealed an old hematoma without neoplastic cells or vascular lesions and these findings were evidence of idiopathic adrenal hematoma.
