Adrenal nodules and masses in four dogs
From Chapter 12 – Adrenals
Figure 12.10. Adrenal nodules and masses in four dogs. A: Sagittal sonogram of the left adrenal gland of a Toy Poodle with pituitary-dependent hyperadrenocorticism. Note the hyperechoic nodules in each pole of the gland, which is thickened (up to 10.4mm). B: Sagittal sonogram of the left adrenal gland of a Mountain Bernese dog with histiocytic sarcoma. A 2cm nodule is identified in the caudal pole of the adrenal gland, deforming the adjacent left renal vein (LRV). Fine-needle aspiration of the nodule confirmed metastasis. C: Transverse sonogram of an adenocarcinoma of the left adrenal gland in an 11-year-old large-breed dog. A large, irregular, inhomogeneous mass (arrowheads) has replaced the left adrenal gland. This mass contains amorphous mineralization, as seen as shadowing hyperechoic foci (arrow),There was no sonographic evidence of vascular invasion, although caudal displacement and compression of the left renal vein (RV) is seen. Sp, spleen. D: Sagittal sonogram of a pheochromocytoma in a 8-year-old boxer crossed. A large inhomogeneous mass is identified medial to the left kidney, but not invading the adjacent vessels.
