case_images: (A) right adrenal schwannoma in the T1 sequence of MRI. The cystic necrotic component can be seen in this imaging study. The schwannoma was shown by a white arrow. (B) Right adrenal schwannoma in the T2 sequence of MRI. The schwannoma was shown by a white arrow.

case_images: Magnetic resonance imaging (MRI) showed a semisolid mass with cystic and necrotic components and peripheral diffusion restriction, which increased suspicion of adrenocortical carcinoma (Figures 1A,B).
case_images: Right adrenal schwannoma in the FDG-PET/CT scan. This mass had an increased FDG uptake. The schwannoma was shown by a white arrow.

case_images: In this imaging study, an enhancement of FDG at the level of malignancy was seen, and the maximum standardized uptake value (SUVmax) was 9.94 (Figure 2).
case_images: Right adrenal schwannoma after laparoscopic transabdominal right adrenalectomy. Two components of adrenal mass can be observed.

case_images: (A) left adrenal schwannoma in the coronal plane of the CT scan. The cystic necrotic component can be seen in this imaging study. The schwannoma was shown by a white arrow. (B) Left adrenal schwannoma in the axial plane of the CT scan. The cystic necrotic component can be seen in this imaging study. The schwannoma was shown by a white arrow.

case_images: F4
case_images: In the CT scan, the size of the left adrenal mass was 125 mm x 102 mm x 123 mm, and heterogeneous contrast enhancement with cystic-necrotic components was observed (Figures 4A,B).
