    1. Case 8In 1997, a 19-yr-old man with a familial history for VHL presented with headaches. MRI of the CNS was normal, but ophthalmological examination showed a right retinal hemangioblastoma that was treated by laser. In 2002, he had right nephrectomy and left nephron-sparing surgery for renal cell carcinoma. At age 27, a palpable mass on the left side of the neck was diagnosed during dental care. CT and MRI revealed a 4-cm carotid body tumor that was removed after selective embolization. Histology revealed a paraganglioma. The patient also has pancreatic cysts. Molecular genetics identified the deletion of exons 2 and 3 of the VHL gene.

      CaseHPOFreeText: At 19Y (in 1997), he presented with headaches, ophthalmological examination showed a right retinal hemangioblastoma (treated by laser). 5 years later (age 24Y) he had a right nephrectomy and left nephron-sparing surgery for renal cell carcinoma. Age 27, a palpable mass on the left side of the neck. CT and MRI revealed a 4-cm carotid body tumor (paraganglioma). The patient also has pancreatic cysts.

    1. Case 11In 1978, an 8-yr-old girl without familial history of VHL was operated for a right pheochromocytoma and at age 13 for a contralateral pheochromocytoma. At age 15, a 4-cm mass at the neck was diagnosed by selective arteriography as a carotid paraganglioma that was removed and histologically confirmed. The patient was then operated twice for cerebellar hemangioblastoma at age 22, leading to the diagnosis of VHL disease. At age 27, the patient was operated again for a retrocaval pheochromocytoma and for islet cell tumors. The patient was also repeatedly treated for bilateral retinal hemangioblastomas leading to blindness at age 32. At age 36, again a pheochromocytoma was removed. Molecular genetic analysis identified the p.Thr157Ile VHL germline mutation. So far, there are no affected relatives.
