Right adrenal lesion. History of neoplasm of uncertain behavior with atypical lymphocytes on bone marrow biopsy. Schwannomatosis. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, signal intensity and size. It contains numerous punctate T2 weighted hyperintensities and larger hyperintensities compatible with numerous cysts. 2.2 x 1.8 cm segment 6 lesion with imaging characteristics consistent with a benign hemangioma.SPLEEN: The spleen is normal in size, morphology and signal intensity without a focal lesion.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: The right adrenal lesion measures 1.8 x 1.8 cm. The lesion demonstrates T2-weighted hyperintensity and mildly heterogeneous postcontrast enhancement. It demonstrates no loss of signal loss on out of phase imaging to confirm an adrenal adenoma. No macroscopic fat is evident to suggest a myelolipoma.KIDNEYS, URETERS: Multiple bilateral punctate T2 hyperintensities, likely cysts. 1.3 cm right renal superior pole cyst.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Heterogeneous marrow signal intensity including postcontrast enhancement and restricted diffusion, with several focal lesion in the pelvic osseous structures. The largest lesion measures 2.8 x 1.7 cm (series 19, image 23). Post bone marrow biopsy changes are noted of the left iliac bone. OTHER: No significant abnormality noted.
1.Non-specific right adrenal lesion does not have imaging characteristics of a lipid-rich adrenal adenoma or myelolipoma. Differential considerations include a metastatic lesion, a neurogenic tumor such as Schwannoma or lipid-poor adrenal adenoma, amongst others.2.Abnormal focal signal abnormality in the osseous structures, the largest of which is in the right iliac bone; suspicious for neoplastic disease.
