Malignant Neoplasm on the Adrenal Gland, Posterior View

Description

Posterior anatomy frames the left suprarenal (adrenal) gland seated on the superomedial pole of the kidney, its normal yellow-orange cortex and medulla distorted by a lobulated, brown malignant neoplasm. The mass expands posteriorly toward the perirenal space, where it would abut the renal capsule and Gerota fascia, and it sits medial to the upper pole renal parenchyma near the renal hilum. Superiorly, the lesion approaches the diaphragmatic crus; medially, it lies in the expected corridor of the adrenal (suprarenal) vein draining toward the left renal vein. That posterior relationship matters when you plan access and anticipate spread. Primary adrenocortical carcinoma and metastatic deposits can invade periadrenal fat and encase the adrenal vein early, and on the left that can tether the tumor to the renal vein, raising the risk of venous tumor thrombus and brisk bleeding during adrenalectomy. Size and posterior contact with the upper pole kidney also drive operative decisions, including en bloc nephrectomy when planes between the adrenal tumor and renal capsule are lost. No clean cleavage plane. Use this artwork to teach retroperitoneal organ relationships in gross anatomy, endocrine blocks (adrenal cortex versus medulla), and surgical anatomy modules covering posterior retroperitoneoscopic adrenalectomy versus transabdominal approaches. It also reads well in clinical education on adrenal incidentaloma workup, adrenocortical carcinoma staging, and radiology-pathology correlation for tumors compressing the superior renal pole.
