ABSTRACT
The clinical data of a case of adrenal alveolar echinococcosis treated and misdiagnosed in our hospital were reported retrospectively. The pre-operative CT examination of this patient showed that the liver S7 segment-the right adrenal gland area showed irregular masses of mixed density lesions, the boundary was unclear, consider the possibility of liver hydatid. During the operation, hydatid was found to only invade the liver capsule, and the primary lesion was the adrenal gland. The right adrenal gland and lesion were resected by urological surgeons. The pathological diagnosis was adrenal alveolar echinococcosis. When the imaging examination considers hepatic alveolar echinococcosis, and the lesion is mainly in the right adrenal gland area, it should be considered that the primary lesion could be in the adrenal gland.
