  • 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 resect'lon 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.

  • Due to its nuclear pleomorphism, knowledge regarding the cytological findings of cerebellar hemangioblastoma can lead to misdiagnosis when using squash specimens, which in other circumstances serves as a useful adjunct in the diagnosis of brain tumors on frozen section. We recently experienced the cytological findings of a cellular variant of cerebellar hemangioblastoma in a 51-year-old man. Squash specimens revealed scattered single tumor cells, with pleomorphic nuclei and cytoplasmic vacuoles, on a hemorrhagic background. The cellular clusters were composed of spindle-shaped endothelial cellsin addition to densely clustered stromal cells. Intranuclear inclusions were frequently seen. The nuclear pleomorphism, bubbly cytoplasmic vacuoles and presence of intranuclear inclusions, seen in the squash specimen, may increase the difficulty of frozen section diagnosis of cerebellar hemangioblastoma. Awareness of the cytologicalfindings of hemangioblastoma is needed to avoid the pitfalls in the intraoperative diagnosis of cerebellar hemangioblastomas.

  • Hemangioblastomas are angioblastic tumors of the central nervous system. Cerebellar hemangioblastomas are traditionally classified into two morphologic types-cystic and solid. Cystic hemangioblastomas are associated with peritumoral edema, but solid hemangioblastomas are not. We report a case of solid cerebellar hemangioblastoma with massive peritumoral edema. An 83-year-old female visited our hospital due to a sudden headache. Five years ago, she had been admitted to our hospital with similar headache and diagnosed with cerebellar hemangioblastoma. Follow-up brain MRI 5 years later showed an increased size of a homogeneous enhancing mass with aggravated peritumoral edema in the left lower cerebellar hemisphere. Cerebral angiography showed a highly vascularized mass in the cerebellum, which was compatible with a solid-type hemangioblastoma.

  • Hemangioblastoma is a benign tumor of vascular origin that develops usually in the posterior cranial fossa. We report a case of supratentorial leptomeningeal hemangioblastoma occurring in a 45-year-old man who received total removal of recurrent cerebellar hemangioblastoma four years ago. He was admitted for the evaluation of severe headache and magnetic resonance image showed a well-enhanced, extra-axial mass in the right parietal region. A presumptive diagnosis was meningioma. It was completely removed with the attached dura. Histological examination including immunohistochemical study showed typical findings of hemangioblastoma. It is emphasized that close observation may be necessary for hemangioblastoma, even after total removal.

  • Supratentorial hemangioblastomas (HBs) are rare, and pituitary stalk HBs are extremely uncommon; therefore, pituitary stalk evaluation is often overlooked. Herein, we report the development of pituitary stalk HB over a 20-year period and the importance of regular long-term follow up for patients with HBs.

  • The cerebellar hemangioblastoma (CHB) has an abundant blood supply and deep anatomical location. Complete surgical resection is generally very difficult. This study investigated the safety and effectiveness of preoperative embolization followed by surgical resection of CHB in a large cohort of patients. A database of 125 CHB patients with surgical resection in Beijing Tiantan Hospital between July 2006 and July 2012 was reviewed. Of those, 46 cases (experimental group) received preoperative embolization, 79 cases (control group) underwent surgery without embolization. Patient demographics, tumor size, duration of surgery, blood loss, blood transfusion, complications and follow-up results were collected and analyzed retrospectively. In the experimental group, the Kamofsky score (KS) was 80-100 in 40 cases (86.9%), 40-70 in 4 cases (8.7%), and below 40 in 2 cases (4.3%). Among 31 cases with follow-up, KS was 80-100 in 27 cases (87.1%), 40-70 in 2 cases (6.5%), and 0 in 2 cases (6.5%). In control group, KS was 80 -100 in 65 cases (82.2%), 40-70 in 6 cases (7.6%), 10-30 in 3 cases (3.8%), and 0 in 3 cases (3.8%). Among 53 cases with follow-up, KS was 80-100 in 44 cases (83.0%), 40-70 in 4 cases (7.5%), 10-30 in 1 case (1.9%), and 0 in 4 cases (7.5%). There were statistically significant differences between the experimental and control groups in tumor size, duration of surgery, amount of intraoperative blood loss and transfusion (p<0.01). However, complications (p=0.31) and follow-up results (p=0.76) showed no significant differences between groups. Selective preoperative embolization of those CHB patients with richer blood supply, higher hemorrhage risk, is safe and effective, and is a reliable adjuvant therapy for complete surgical resection of CHB.
