case_images: The initial CT abdomen with and without contrast showed a 3.3 cm left adrenal indeterminate mass with an absolute and relative washout of 21.9% and 10.1%, respectively, which did not meet the washout criteria for an adrenal adenoma (Figure 1).
case_images: Follow-up MRI, ten months later, showed significant enlargement of the left adrenal mass, measuring 6.5 x 5.1 x 5.0 cm.

case_images: A follow-up MRI, ten months later, showed significant enlargement of the left adrenal mass, which at the time measured 6.5 x 5.1 x 5.0 cm (Figure 2).
case_images: Immunohistochemical findings postresection. (a) Malignant epithelioid cells with moderate eosinophilic cytoplasm and rhabdoid features along with prominent lymphoid infiltrate (200x). (b) Higher magnification (400x). (c) Loss of INI-1 stain in neoplastic cells; background inflammatory cells stained positive with INI-1.

case_images: The microscopic analysis of the tumor showed malignant epithelioid cells with moderate eosinophilic cytoplasm and rhabdoid features (Figure 3). Prominent lymphoid infiltrate was associated with the tumor cells (Figure 3). Figure 3(c) demonstrates the loss of INI-1 stain in neoplastic cells; background inflammatory cells stained positive with INI-1. Focal immunoreactivity for calretinin was identified.
