CaseHPOFreeText: History of arterial hypertension and retinitis causing loss of vision in the left eye due to cataract and amblyopia in the right eye. History of retinal hemangioblastoma was presumed. Diagnosed with diabetes mellitus at the time of the study. MRI showed multiple enhancing nodular lesions of the spinal canal, later confirmed to be a hemangioblastoma. Whole body PET scan showed a heterogeneous mass in the right kidney and focal mural thickening in the sigmoid colon. Colonoscopy showed an ulceroinfiltrative lesion in the sigmoid colon and a polypoid lesion in the rectum subsequently confirmed as a adenocarcinoma and high grade tubular adenoma with focal carcinoma, respectively. Histologic examination of the kidney revealed renal clear cell carcinoma. In the sigmoid colon, gross pathology showed an ulcerofungating tumor and some regional lymph nodes were metastasis. The rectum specimen was confirmed to be a well differentiated adenocarcinoma. Brain MRI showed three enhancing lesions in bilateral cerebellar hemispheres and left cerebellar tonsil, suggesting hemangioblastomas. Histologic examination of liver revealed a metastatic adenocarcinoma. Pathologic finding indicated that the aortocaval lymph node was metastatic carcinoma, favoring renal clear cell carcinoma.
