    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. A female patient observed reduced vision in the right eye at age 17 years. She was diagnosed with retinal angiomatosis of the right eye. Laser therapy and brachytherapy were performed. Vision of the right eye remained reduced to 15%. At age 24, a hemangioblastoma of the cervical spinal cord was resected. At age 27, she underwent craniotomy for a cerebellar hemangioblastoma. Genetic testing revealed the mutation VHL c.394 C > T, which predict a truncated VHL protein (Q132X). In 2007, a 20 mm diameter left renal tumor was detected but not resected owing to its small size, as internationally recommended [1].In 2009 at age 38, abdominal MRI and CT angiography showed, in the axial view, a solid, 3.6 × 3.3 cm tumor of the pancreatic tail (Fig. 2a). Early arterial phase imaging after contrast injection revealed that the tumor had significant hyperperfusion. In addition, multiple pancreatic cysts were noted.
