case_images: Positron emission tomography-CT (PET-CT) was subsequently performed, which also showed a large, multi-loculated, hypermetabolic, cystic mass in the left adrenal region, and additionally showed hypermetabolic masses in the lung, peritoneum, liver, gallbladder, and multiple lymph nodes, suggesting distant metastasis. ( Figure 1 ).

case_images: Pathological examination of the hypermetabolic mass in pelvic tissue biopsy sample suggested epithelioid hemangioendothelioma ( Figure 2 ).
case_images: Computed tomography images before and after treatment. Review after immunotherapy showed significant reduction in the sizes of the left adrenal region. The time of CT was (A) 2021-07-30, (B) 2021-09-13, (C) 2021-11-30, (D) 2022-02-20, (E) 2022-05-12, (F) 2022-08-09.
