Supratentorial Hemangioblastoma in Adults: A Systematic Review and Comparison of Infratentorial and Spinal Cord Locations

BACKGROUND

Supratentorial hemangioblastomas are benign and highly vascularized neoplasms that appear most often in the spine and posterior cranial fossa. They can also be located in the supratentorial compartment of the brain. We conducted a systematic review of the literature to better understand the clinical insights of supratentorial hemangioblastoma in adults.

METHODS

Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, the authors reviewed the English-language literature in the PubMed/MEDLINE database on supratentorial hemangioblastoma in adults, published in the past 40 years. We analyzed the differences between sporadic hemangioblastomas and hemangioblastomas associated with von Hippel-Lindau disease. In addition, we compared the characteristics of supratentorial hemangioblastomas with infratentorial and spinal cord locations.

RESULTS

We reviewed 92 articles, describing 157 supratentorial hemangioblastomas in a total cohort of 148 adult patients. Most articles reporting supratentorial hemangioblastomas were published in the United States. Supratentorial hemangioblastomas occur more frequently in women than men. The median age at the time of diagnosis was 44.48 years. The sellar/parasellar region was the most commonly tumor location, while the most common morphological type was the solid type. Almost 80% of hemangioblastomas were completely resected; the outcome was favorable in more than 3 fourth of patients.

CONCLUSIONS

Given their rarity, the literature on supratentorial hemangioblastomas is limited and based mostly on case reports. Complete surgical resection is the first choice of treatment and is associated with a good treatment outcome.

Preoperative Diagnosis of Suprasellar Hemangioblastoma with Four-Dimensional Computed Tomography Angiography: Case Report and Literature Review

Purpose Our case report presents the first case of suprasellar hemangioblastoma diagnosed preoperatively with dynamic computed tomography angiography (four-dimensional [4D] CTA) in a patient without Von Hippel-Lindau (VHL) disease. We illustrate the imaging characteristics of these exceedingly rare tumors and discuss the role of 4D CTA in confirming this diagnosis and guiding surgical management. Finally, we present a literature review of imaging findings, differential diagnosis, management, and prognosis.

Case A 39-year-old woman known for diabetes mellitus type II and dyslipidemia presented with headache, bitemporal hemianopsia, and mild hyperprolactinemia. Initial diagnosis of suprasellar meningioma separate from pituitary gland was revised to definitive diagnosis of suprasellar hemangioblastoma after 4D CTA.

Conclusion Suprasellar hemangioblastomas are extremely rare, often associated to VHL disease. They present as enhancing as suprasellar mass with prominent intra- and peritumoral vascular flow-voids on magnetic resonance imaging. 4D CTA confirms their vascular nature, demonstrates characteristic rapid shunting with feeding arteries, and enlarged draining veins, and is important in guiding surgical management.

Suprasellar Hemangioblastoma with Reversible Edema-Like Change Along the Optic Tract: A Case Report and Literature Review

BACKGROUND

Hemangioblastomas usually occur in the cerebellum and are often a component of von Hippel-Lindau disease. Edema-like changes along the optic tract are commonly observed in association with tumors in the sellar and suprasellar regions, such as craniopharyngiomas and pituitary adenomas. Here, we describe a case of sporadic suprasellar hemangioblastoma with edema-like changes along the optic tract that completely resolved after surgery.

CASE DESCRIPTION

The patient was a 28-year-old woman with failing vision and a bitemporal hemianopia. Magnetic resonance imaging revealed a tumor accompanied by a 10-mm cyst. Fluid-attenuated inversion recovery axial magnetic resonance imaging revealed a hyperintense region along the optic tract. Other regions of the central nervous system were normal. Endoscopic transsphenoidal surgery was performed, and the histopathologic findings confirmed hemangioblastoma. Six months after surgery, the edema-like change along the optic tract had disappeared. The patient is doing well without pituitary insufficiency, pituitary hormone medications, or signs of tumor recurrence. In addition, the genetic test was negative for von Hippel-Lindau mutations.

CONCLUSIONS

When examining a patient with suprasellar tumor, clinicians must consider the possibility of hemangioblastoma. Adequate treatment can improve the edematous change and visual disturbance.

Surgical approach for suprasellar hemangioblastomas preserving the pituitary stalk: Review of the literature and report of a further case

Hemangioblastomas (HBLs) are challenging vascular tumours with rare suprasellar location Surgery is recommended in patients with visual impairment, endocrine disorders or hydrocephalus. Surgical removal of pituitary stalk HBLs is challenging due to their location and high vascularity. Our narrative review was guided by the question: "what is the more suitable surgical approach to excise a suprasellar HBL?". Pertinent English literature was scrutinized from database inception to October 2016. Eighteen articles matched our selection criteria. Among the surgically treated patients, 4 were treated through a trans-sphenoidal (TS) approach, 13 through a transcranial approach (2 of them after TS failure). Five other cases were treated with radiotherapy (adjuvant in 3 cases) and 9 patients were managed with simple observation and/or medical treatment. We add a case of complete suprasellar HBL resection through an orbito-zygomatic (OZ) craniotomy with extradural anterior clinoidectomy (EAC). To achieve satisfactory oncologic results with acceptable morbidity for symptomatic suprasellar HBLs, complete tumour removal with pituitary stalk sparing should be attempted through an OZ craniotomy with EAC that provides adequate exposure of the tumour, its vascular supply and the adjacent neural structures.

Surgical Treatment of Hemangioblastoma in the Pituitary Stalk: An Extremely Rare Case

Hemangioblastoma (HBL) in the pituitary stalk is extremely rare. Only 16 such cases have been reported in the past and 5 cases have been treated with surgical procedure. Here, we report surgical case of HBL in the pituitary stalk diagnosed in a 34-year-old woman. The patient underwent a gross-total resection via the modified lateral supra-orbital approach. No recurrence was observed in two years after surgery. To our knowledge, this is the 17th case of HBL in the pituitary stalk and the 6th surgical case. If the tumor is symptomatic and the volume is over 5 cubic centimeters as in our case, we recommend that the surgical resection of the HBL in the pituitary stalk is a more safe and reasonable than radiotherapy.

Infundibular Hemangioblastoma in a Patient with Neurofibromatosis Type 1: Case Report and Review of the Literature

BACKGROUND

Supratentorial hemangioblastomas are rare tumors, most commonly occurring in the sellar/suprasellar region, cerebrum, and ventricle. They are generally found in patients with von Hippel Lindau disease but have infrequently been reported in patients without this syndrome.

CASE DESCRIPTION

A 35-year-old woman with a history of neurofibromatosis type 1 presented to our care with visual loss and headaches. Magnetic resonance imaging of the brain demonstrated an 8-mm cystic, contrast-enhancing lesion abutting the optic chiasm and optic tracts. The patient's endocrine profile was unremarkable. The tumor was resected using an endoscopic expanded transsphenoidal approach. Pathologic evaluation was consistent with hemangioblastoma. Postoperatively, the patient experienced an improvement in her visual symptoms.

CONCLUSIONS

Hemangioblastoma should be included in the differential of sellar/suprasellar mass lesions, particularly in patients with von Hippel Lindau disease. Small suprasellar lesions may be safely and effectively removed using an expanded transsphenoidal approach.

Sporadic Hemangioblastoma in the Pituitary Stalk: A Case Report and Review of the Literature

Hemangioblastomas in the pituitary stalk are especially rare. Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease. Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman. Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function. In this case, complete surgical excision was shown to be an effective treatment option for symptomatic pituitary stalk hemangioblastoma, and we suggest careful evaluation of any highly enhancing mass with a signal void in the pituitary stalk preoperatively, even if no VHL disease is evident.

Suprasellar hemangioblastoma mimicking a craniopharyngioma: result of extended endoscopic transsphenoidal approach--case report

Hemangioblastoma in the suprasellar region is rare. We present a case of a suprasellar hemangioblastoma that underwent surgical resection using an extended endoscopic transsphenoidal approach. A 64-year-old female patient presented with headache and decreased visual acuity for the last four years, computed tomography (CT) and magnetic resonance imaging (MRI) revealed a 2.5 cm irregular lesion in the suprasellar region. Our preoperative presumptive diagnosis was craniopharyngioma. The patient underwent an extended endoscopic transsphenoidal approach, the mass was subtotally removed. An endoscopic endonasal repair was needed due to the cerebrospinal fluid (CSF) leak. However, 1 month later, the patient got disturbance of consciousness because of the hydrocephalus. Ventriculoperitoneal shunt was used to solve the problem. Pathological findings were compatible with hemangioblastoma. Suprasellar hemangioblastoma is very rare. Any highly vascular lesions located in the suprasellar region should alert the surgeon to the possibility of hemangioblastoma. Extended endoscopic transsphenoidal approach adopted by us should not be the first choice of the treatment procedure for this kind of large and vascular tumor.
