“…Except for the cases originating from cranial nerves, 15 cases (including the present case) of CPA hemangioblastoma have been reported with MR findings [Table 1]. [1,2,5,[7][8][9]11,12,14,[16][17][18]21] e patient's ages ranged from 12 to 70 years (mean 48.2 years), with a male: female ratio of 6:9, and no patients had VHL. e tumor type was classified as solid in six cases, solid/cystic in six, and cystic in three.…”

“…[2] Extra-axial hemangioblastomas are rarely described in the literature, particularly those originating from the cerebellopontine angle (CPA).

[3,6,10] In particular, large solid CPA hemangioblastomas represent a surgical challenge because of their arteriovenous malformation-like hypervascularity, the multi-directional blood supply, the exploration of wide operative field, and the circumferential dissection.…”

Background: Extra-axial cerebellopontine angle (CPA) hemangioblastomas are rare clinical entity and surgical treatment is challenging due to the anatomical difficulties and multi-directional blood supplies. On the other hand, the risk of endovascular treatment for this disease has also been reported. Herein, we successfully applied a posterior transpetrosal approach to remove a large solid CPA hemangioblastoma without preoperative feeder embolization. Case Description: A 65-year-old man presented with a complaint of diplopia during downward gaze. Magnetic resonance imaging revealed a solid tumor with homogeneous enhancement measuring about 35 mm at the left CPA, and the tumor compressed a left trochlear nerve. Cerebral angiography disclosed tumor-staining fed by both left superior cerebellar and left tentorial arteries. After the operation, the patient’s trochlear nerve palsy improved dramatically. Conclusion: This approach offers more optimal surgical working angle to the anteromedial part compared to the lateral suboccipital approach. In addition, the devascularization from the cerebellar parenchyma can be performed more reliably than the anterior transpetrosal approach. After all, this approach can be particularly useful when vascular-rich tumors receive blood supplies from multiple directions.

BACKGROUND Hemangioblastoma (HB) is a rare tumor, comprising about 2% of all intracranial tumors. Although it is a benign tumor, due to the abundant blood supply and its close relationship with adjacent cerebral blood vessels, surgical resection is difficult and may cause complications such as bleeding. If HB can be correctly diagnosed before surgery, complications can be avoided by methods such as vascular embolism before surgery. CASE SUMMARY A 51-year-old male patient was admitted to our hospital because of blurred vision in his left eye for 2 years. Ophthalmological examination revealed oculus dexter vision acuity of 1.0 and oculus sinister vision acuity of 0.6. His left vision had tubular visual field, while his right vision had a partial defect. Computed tomography and magnetic resonance imaging showed a mass lesion at the left anterior base of the skull, which could have been a meningioma. During the operation, the tumor was found to be located at the entrance of the left optic nerve tube, closely adhering to the left optic nerve and the blood supply was extremely abundant. The tumor was carefully separated and diagnosed as HB postoperatively after pathological examination. CONCLUSION A rare HB at the anterior skull base could be distinguished by its imaging features, which is essential to the surgical procedures.

Noncystic cerebellopontine angle hemangioblastoma: A case of an atypical location

Abstract: Highlights Cerebellopontine angle hemangioblastoma is a rare condition. Magnetic resonance imaging evaluation is important for the differential diagnosis of hemangioblastoma. Surgical planning in hemangioblastoma surgery is a central key point.
