    Laparoscopic Organ-Sparing Resection of Von Hippel-Lindau Disease-Associated Pancreatic Neuroendocrine Tumors

    1. ClingenBaseline 14 Nov 2026
      The 24 year-old woman was diagnosed at age 20 with VHL. She had bilateral retinal angiomas that were treated by laser coagulation in 2003. The left eye was treated by laser coagulation several times and subsequently by vitrectomy. Molecular genetic investigation of a blood sample showed a large deletion of exon 3 of the VHL gene. The family history was negative.The patient was admitted for a complete clinical investigation to the Freiburg Preventive Medicine Center. MRI of the CNS revealed multiple hemangioblastomas of the spinal cord but no intracerebral hemangioblastomas. MRI of the abdomen showed multiple cysts in the pancreatic head with a maximum diameter of 4 cm and pancreatic duct ectasia. In addition, a lesion was detected in the pancreatic tail that measured 2.3 × 1.6 cm in the axial view (Fig. 1a). There was moderate contrast enhancement of the tumor. The kidneys and paraganglia were without pathological changes. Two years later, the tumor had grown to 1.9 × 2.9 cm.

    Laparoscopic Organ-Sparing Resection of Von Hippel-Lindau Disease-Associated Pancreatic Neuroendocrine Tumors
    1
    1. ClingenBaseline 02 Nov 2026
      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.

      GroupID: 6B

      DiseaseAssertion: assumed VHL

      GroupSize: 9

      GroupNumberMales: N/A

      GroupNumberFemales: N/A

      GroupEthnicity: Chinese

      GroupAgeRange: 33.8Y +/- 17.6Y

      GroupInfo: Clinical characteristics of 258 patients from 80 unrelated Chinese families were reported in this study. Grouped by the 21 mutations found, 3 families with 13 members total were described. it is unclear how many distinct families are reported in group 6B. 9 individuals were described. Phenotypic information was given for this mutation.

      GroupPresentingHPOs: HP:0010797; HP:0009711; HP:0005584; HP:0001737; HP:0009715 (hemangioblastoma, retinal capillary hemangioma, renal cell carcinoma, pancreatic cysts, papillary cystadenoma of the epididymis)

      GroupHPOFreeText: 7 of the 9 members presented with CNS hemangioblastoma (mean age of 29.9Y), 2/9 had retinal angiomas at 25Y and 35Y, 1 had renal cell carcinoma (at 30Y), pancreatic cysts in 2 members (with an age of onset of 30 and 31Y), and 1 member with a genital system tumor (epididymis or broad ligament) at 24Y
