PatientID: 1

KindredID: 1

Case: F, 44Y0M, Ethnicity Unknown

DiseaseAssertion: assumed VHL

FamilyInfo: The patient has a notable family history. Her eldest brother had multiple RCCs in both kidneys, bilateral cerebellar hemangioblastomas, and pheochromocytoma in his left adrenal gland (see Patient 2). Her daughter also underwent cortex-sparing adrenalectomies for bilateral pheochromocytomas as well as hemangioblastoma resection in her left cerebellum at age of 19 years, although no testing for VHL was stated.

CasePresentingHPOs: HP:0006748, HP:0030405, HP:0006880, HP:0000107, HP:0005584 (adrenal pheochromocytomas, pancreatic endocrine tumour, cerebellar hemangioblastoma, renal cyst, renal cell carcinoma)

CaseHPOFreeText: Patient diagnosed at age 29 with bilateral pheochromocytomas when she presented with severe hypertension and two large masses (greater than 6 cm) in her bilateral adrenal glands. At 38 years old, she underwent a resection for a mass found on her pancreas, with pathological analysis of the mass revealing a pancreatic neuroendocrine tumor. At 42 years old, a follow-up CT scan revealed two heterogeneous contrast-enhanced masses, one on the right kidney and one on the left adrenal gland.

CaseHPOFreeText: Presented at age 39 with bilateral renal tumors (2 right side, 3 left side). Pathological evaluation revealed clear cell type renal cell carcinoma (fig. 1, B). After 2 years multiple pancreatic cysts were noted. Two years later 6 bilateral renal cell carcinoma lesions developed. Five years later at age 48 years mental confusion developed and brain MRI showed a cerebellar lesion; histological evaluation revealed cerebellar hemangioblastoma.
