CasePresentingHPOs: HP:0010797; HP:0002858; HP:0012503; HP:0000141 (hemangioblastoma; meningioma; pituitary lesion; amenorrhea)

CaseHPOFreeText: 1-year history of amenorrhea, she was found to have a brainstem hemangioblastoma, posterior fossa meningiomas and a pituitary spaceoccupying lesion causing hyperprolactinemia. Complete resection of the brainstem hemangioblastoma and posterior fossa meningiomas was achieved in one single operation via a sub-occipital posterior combined with retrosigmoid approach. The patient was later discharged without obvious postoperative complications.

Case: M, 66Y0M, Ethnicity Unknown

DiseaseAssertion: VHL

FamilyInfo: The patient’s elder sister died of a cerebellar tumor of unknown pathology at 30Y. As well, the patient’s son presented with cerebellar hemangioblastoma and was diagnosed with VHL disease.

CasePresentingHPOs: HP:0002666; HP:0006880; HP:0100009; HP:0005584 (Pheochromocytoma, cerebellar hemangioblastoma, intracranial meningioma, renal cell carcinoma)

CaseHPOFreeText: The 66Y male patient presented with mild dementia, and was found to have multiple tumours in the cerebellum; the tumours were resected, and histological examination determined that the tumours included meningothelial meningioma and a capillary hemangioblastoma. The patient was also found to have renal cell carcinoma, and underwent nephrectomy. The patient had also previously undergone resection for a giant pheochromocytoma associated with malignant hypertension 20 years prior at 46Y. The patient died of multiple cerebral infarctions and RCC three years after the surgery to remove the cerebellar tumours.
