    1. Case 1 A 33-year-old woman with no unusual medical history presented in November 1999 with an 8-month history of right-sided otalgia and progressive hearing loss. Otoscopic examination revealed a reddish, raspberry-like hypotympanic mass behind a normal tympanic membrane. Audiometry revealed complete hearing loss of the right ear. Computed tomographic (CT) scan and magnetic resonance imaging (MRI) revealed lysis of the posterior face of the petrous pyramid by a voluminous heterogenous mass invading the infralabyrinthine and retrolabyrinthine regions (Fig. 1, A and B) and the posterior cranial fossa (Fig. 1, C and D) and an infracentimetric hypervascular lesion in the right cerebellum highly suggestive of a hemangioblastoma. These findings evoked the diagnosis of ELST associated with VHL disease.

These findings evoked the diagnosis of ELST associated with VHL disease. Abdominal ultrasonography and MRI of the patient showed multiple pancreatic cysts but no renal or adrenal gland abnormalities. Regular medical follow-up 4 years after the discovery of the disease showed a right renal cyst and centimetric tumor of the left kidney.

      KindredID: 1

      Case: M, 46Y0M, Ethnicity Unknown

      DiseaseAssertion: Assumed VHL

      FamilyInfo: The patient’s grandmother and two uncles had died with cerebellar hemangioblastoma, although genetic testing was not performed. The patient’s father presented with cerebellar hemangioblastoma, retinal hemangioblastoma, clear cell renal cell carcinoma, and serous cystadenoma at 68Y, adrenal pheochromocytoma at 73Y, and clear cell renal cell carcinoma metastasis in the thyroid at 74Y; he was found to carry the same mutation the patient carried. One of the patient’s sons, a 10Y male, was also found to carry the same mutation as the patient but was asymptomatic. Genealogical inquiry also revealed that the patient was distantly related to a known VHL family; one member, a 47Y male, was previously operated on for CNS hemangioblastoma, RCC and symptomatic pheochromocytoma and was found to carry the same mutation as the proband. Another female member had previously presented with retinal hemangioblastoma before becoming deceased at 37Y. The paper also asserted that the patient’s grandmother and two distant relatives carried the mutation, although genotyping was not performed and phenotypic information was not provided.

    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.

      DiseaseAssertion: assumed VHL

      FamilyInfo: The transversion mutation was found and confirmed in 4 patients (II-2, III-2, III-6, III-10, III-11) and 3 carriers (III-3, III-9, III-14). At least 5 additional members had VHL phenotypes, but had all passed away before genetic testing. Could be assumed and deduced their genetics due to pedigree showing future linear relations of this mutation all in generation III.

    1. 2. Materials and methods2.1. PatientThe 32-year-old male patient was admitted to Xiangya Hospital in 2006 and presented with progressive back and neck pain, and numbness and weakness of both legs which had continued for 1 month followed by fecal and urinary retention for 5 days. The MRI (1.5 Tesla) of the brain and entire spinal cord showed multiple lesions in the cerebellum, brain stem, and spinal cord, which were obviously enhanced and highly suggestive of hemangioblastomas (Fig. 1a–e). Subsequent evaluation, by MRI, of the abdomen revealed a solid kidney tumor (Fig. 1f). He underwent surgical resection for hemangioblastomas of T10 and T12 of the spinal cord, which appeared bright red at surgery. The pathological examination of the tissues showed many small blood vessels, most of which were a capillary plexus. Vascular endothelial cells were flat and distributed within a large number of stromal cells. Some of the vascular endothelial cells formed solid masses and cords. Between the capillary plexus, various forms of stromal cells were found, including nest-like or sheet arrangements with hyperchromatic nuclei, rich cytoplasm, rich lipid vacuoles and rare or no mitoses. Some foam cells and adipose-like cells were also found. Immunohistochemistry of the biopsied tissues from the lesions in the spinal cord were negative on immunostaining (–) for glial fibrillary acidic protein (GFAP), CD68, cytokinin (CK)-pan and epithelial membrane antigen (EMA), but stained positive (+) for factor 8 related antigen (F8RAg). Vascular endothelial cells were F8RAg(+) but stromal cells were F8RAg(–). Vascular endothelial cells and stromal cells were all immunonegative for GFAP, EMA, CK-pan, and CD68 (Fig. 1g, h). The patients’ symptoms resolved after surgery. At 5-year follow-up his condition did not recur or deteriorate, but active surveillance was continued.12Download : Download high-res image (1MB)Download : Download full-size imageFig. 1.

(h) Immunohistochemistry of the biopsied tissue from the lesions at T10 and T12 in the spinal cord of the patient with VHL (factor 8 related antigen stain, ×400).After genetic counseling, all family members of the patient (his parents, sister, son, sister’s son, brother, and brother’s son) were recruited into this study. His 66-year-old father and 63-year-old mother were both in good health without clinical symptoms of VHL. They did not undergo a whole-body examination, but all other family members underwent clinical examination, including ophthalmoscopy, MRI of the CNS, and ultrasonography of the abdomen, to exclude the disease. Informed consent was obtained from all individuals before their participation in the study.

    1. Patient 1 The first patient had no familial history of VHL disease and was 21 years old when he experienced a sudden right hearing loss. The resulting cophosis was irreversible. The radiological work-up revealed an osteolytic mass of the right temporal bone of heterogeneous signal on both T1- and T2-weighted images (Fig. 1), consistent with the diagnosis of endolymphatic sac tumor. The tumor invaded the otic capsule and the petrous apex but did not extend in the cerebellopontine angle. Its mean tumor diameter (MTD) at diagnosis was approximately 2.6 cm (formula—MTD = (length×width×height)1/3MTD = (length×width×height)1/3 {\hbox{MTD = }}{\left( {{\hbox{length}} \times {\hbox{width}} \times {\hbox{height}}} \right)^{{1/3}}} ) [16]. The rest of the neurological exam was normal and a conservative management was decided. During follow-up, the patient suffered from other manifestations of VHL disease: retinal and central nervous system hemangioblastomas, pheochromocytoma, renal tumors, and pancreatic cysts. The germline mutation of the VHL gene was also identified (c.337C>T, p.Arg113X). After 20 years of radiological surveillance, the size of his endolymphatic sac tumor remains stable (Fig. 2). Apart from his deafness, the patient does not suffer from any vestibular symptoms and his facial function is normal (House and Brackmann grade I).
