Weight loss. Adrenal mass. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, size and signal intensity. There are multiple small well-defined lesions T1-weighted hypointense lesions demonstrating peripheral nodular discontinuous enhancement which progresses centrally compatible with multiple cavernous hemangiomas.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: The left adrenal fossa lesion measures 2.7 x 2.1 cm (series 15/97). The lesion appears separate from the adrenal gland, pancreas, kidney and spleen. The lesion does not demonstrate loss of signal intensity on out of phase imaging to suggest a lipid rich adenoma. Lesion appears to demonstrate peripheral thick enhancement which appears to progress centrally. KIDNEYS, URETERS: Few simple cysts.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
The left retroperitoneal mass appears separate from the adrenal glands pancreas kidney and spleen. It demonstrates peripheral thick enhancement which progresses centrally. Differential considerations include a pheochromocytoma (correlate with urine markers), a hemangioma in a splenule (consider RBC scan) or neuroendocrine tumor of unclear origins.
