Meningeal Supratentorial Hemangioblastoma in a Patient with Von Hippel-Lindau Disease Mimicking Angioblastic Menigioma

Hemangioblastomas are sporadic tumors found in the cerebellum or spinal cord. Supratentorial hemangioblastomas are rare, and those with meningeal involvement are extremely rare and have been reported in only approximately 130 patients. Here, we report the case of a 51-year-old female patient with supratentorial meningeal hemangioblastoma detected 5 years after surgical resection of an infratentorial hemangioblastoma associated with von Hippel-Lindau disease. Patients with von Hippel-Lindau syndrome are at risk for developing multiple hemangioblastomas, with new tumor formation and growth and possible meningeal infiltration. Regular lifelong follow-up in at-risk patients is recommended and should include the differential diagnosis of dural-based tumors such as angioblastic meningioma and metastatic renal cell carcinoma.     

Long-Term Follow-Up Clinical Courses of Cerebellar Hemangioblastoma in von Hippel-Lindau Disease : Two Case Reports and a Literature Review

Although cerebellar hemangioblastomas are histopathologically benign, they yield a degree of malignant clinical behavior in long-term follow-up. We present two cases of long-term progression of renal cell carcinoma, which had been diagnosed as renal cysts during treatment for cerebellar hemangioblastoma. A 14-year-old male with von Hippel-Lindau disease was admitted for a cerebellar hemangioblastoma with multiple spinal hemangioblastomas and a renal cyst. After primary total resection of the cerebellar hemangioblastoma, the patient required two further surgeries after 111 and 209 months for a recurrent cerebellar hemangioblastoma. Furthermore, he underwent radical nephrectomy as his renal cyst had progressed to renal cell carcinoma 209 months after initial diagnosis. A 26-year-old male presented with multiple cerebellar hemangioblastomas associated with von Hippel-Lindau disease and accompanied by multiple spinal hemangioblastomas and multiple cystic lesions in the liver, kidney, and pancreas. He underwent primary resection of the cerebellar hemangioblastoma in association with craniospinal radiation for multiple intracranial/spinal masses. Unexpectedly, a malignant glioma developed 83 months after discovery of the cerebellar hemangioblastoma. At the same time, renal cell carcinoma, which had developed from an initial renal cyst, was diagnosed, and a radical nephrectomy was performed. In the view of long term clinical course, cerebellar hemangioblastoma associated with von Hipple-Lindau disease may redevelop even after primary total resection. In addition, associated lesions such as renal cysts may also progress to malignancy after the passing of a sufficient length of time.     

儿童中枢神经系统血管母细胞瘤的显微手术治疗

Diagnosis and microsurgical treatment of spinal hemangioblastoma

Spinal cord hemangioblastomas are rare benign tumors, with difficult surgical management and poor prognosis due to high vascularization. We aim to evaluate the diagnostic methods and microsurgical treatment of spinal cord hemangioblastoma. This retrospective study assessed 25 patients treated for spinal hemangioblastoma using microsurgery at Beijing Tiantan Hospital and Department of Neurosurgery, The General Hospital of Chinese People’s Armed Police Forces, between October 2008 and October 2013. Clinical, imaging, and treatment data were collected. Meanwhile, efficacy was assessed with the McCormick grading system for spinal cord function. The symptoms lasted 17.0 ± 15.1 months. Sixteen (64 %) patients were suffering from von Hippel-Lindau disease; magnetic resonance imaging revealed the lesions in all patients. Intraoperative fluorescence angiography was helpful in identifying the feeding arteries and draining veins. Total tumor removal was achieved in all subjects. Patients were followed up for 21.3 ± 8.5 months. One week after surgery, neurological symptoms were improved in 22 patients, remained stable in 2 patients, and were aggravated in 1. The latter patient began to recover 7–10 days after surgery and was completely recovered within a month. At the last follow-up, all patients were alive, and all showed a McCormick grade ≤II. Microsurgery seems effective in the treatment of spinal cord hemangioblastoma. Intraoperative fluorescence angiography is helpful in defining the resection scope, to reduce intraoperative bleeding and prevent spinal swelling, which results in improved success rate.     

颅内血管母细胞瘤影像学分型与手术策略的探讨

目的探讨颅内血管母细胞瘤的诊断和治疗。方法回顾性分析58例血管母细胞瘤病人的临床资料,根据MRI检查将肿瘤分为4型：单囊伴单瘤结节型40例,实质型8例,囊实型6例,多发结节型4例。采用后正中、旁正中或枕下人路手术。结果肿瘤全切除56例,大部分切除2例。术后脑肿胀1例,再出血1例,予再次手术。无死亡病例。术后随访1～5年,肿瘤复发2例。结论影像学分型对于指导手术是必要的,应根据瘤结节位置,合理选择手术人路。实质型和囊实型肿瘤手术时间长,手术风险大,术前可行造影检查,必要时栓塞治疗。
