Mineralized left adrenal gland mass with attached thrombus/invasion into the vena cava.

Outcome

A surgical approach is a potential, if the surgeon is prepared for thrombus-occupation of the vena cava to an extent of approximately 4 cm cranial to the left adrenal mass. No overt evidence of metastatic disease was noted. Surgical consultation was recommended. The mineralization suggested carcinoma. The patient was sent to a referral facility for surgical consultation and was scheduled for left adrenalectomy with removal of the associated vena cava thrombus.

Image Interpretation

Left adrenal gland masses measuring 1.72 cm x 1.57 cm were noted, and seen invading the vena cava when visualized from the right approach; the vena cava was invaded for approximately 4 cm. The mineralizations seen would suggest carcinoma. The right adrenal gland was recognized as having normal shape, size, position and echogenicity for this breed. The phrenic vasculature, glandular echogenicity and detail were unremarkable. Capsule, cortex, and medullary definition were normal for this age patient. The right adrenal gland measured 1.5 cm in length and 0.5 cm in width.
