(A,B) Computed tomography scan revealed an esophageal tumor in the upper to middle thoracic esophagus (arrow) and enlarged subcarinal lymph nodes (arrow head) (1A). The left adrenal gland was enlarged (double arrows), suspected to contain a metastasis from the primary esophageal cancer (1B).

CT scan revealed an esophageal tumor in the upper to middle thoracic esophagus and enlarged subcarinal lymph nodes (Fig. 1A), main bronchus lymph nodes, right recurrent nerve lymph nodes and an enlarged left adrenal gland (Fig. 1B).
(A,B) Magnetic Resonance Imaging revealed that there is no difference in signal intensity comparing in-phase (2A) and out-of phase images (2B). The adrenal tumor had no fat component.

MRI revealed an adrenal tumor with no fat component (Fig. 2A, B).
The positron emission tomography/computed tomography scan showed a left adrenal gland (arrow) with high uptake of 18F-fluoro-2-deoxy-d-glucose, SUVmax 10.13.

The adrenal tumor was soft, and the split surface was black (Fig. 4).
Histologically, cells with eosinophilic cytoplasm (arrow heads) proliferated monotonically and uniformly, contain brown pigment (arrows) by H&E staining (x400), and diagnosed as a BAA.
