Right adrenal gland is markedly increased in size (3.3 cm) due to the presence of a heterogeneous mass. The latter is lining the caudal vena cava; however, a possible wall infiltration cannot be excluded.

Urinary bladder presents hyperechoic non-gravity dependent material.
Wall thickness within normal limits.
An irregularly-rounded parietal lesion, protruding into the lumen and positive on color Doppler interrogation, is observed arising from the left ventro-lateral aspect of the urinary bladder neck.

Presence of mixed fluid/gaseous content filling the gastric lumen.
A focal mucosal thickening of the greater curvature is observed, protruding into the lumen and positive to color Doppler interrogation.
Wall layering is preserved.

A fusiform endoluminal hyperechoic structure, partially obstructive, is observed in the aortic lumen between the renal artery and the aortic trifurcation.

Transverse section of the aortic lesion previously described, with the hyperechoic partially obstructive endoluminal structure and surrounding blood flow.

1. Right adrenal neoplasia (DDx adenoma, carcinoma, pheochromocytoma), likely secreting considering controlateral adrenal atrophy.
2. Non-specific bladder lesion DDx: polypoid cystitis vs neoplasia (e.g. TCC) vs idiopatic.
3. Gastric lesion DDx polyp vs neoplasia (e.g. lymphoma, carcinoma, leiomyoma).
4. Aortic thromboembolism.

Diagnostic confirmation of adrenal hyperadrenocorticism was obtained with dexamethasone suppression test; traumatic catheterization is proposed for further evaluation of bladder mass, and endoscopic biopsy for gastric lesion.
