“…The vessels that make up this malformation are dilated and dysplastic. They are jointly referred to as the nidus, which is connected with feeding arteries and drainage veins without the presence of brain parenchyma cells interspersed between the nidus vessels [ 5 , 42 , 43 , 44 ]. These connections allow AVMs to exert circulatory arrest on the surrounding brain structures [ 45 ].…”

Vascular malformations are frequent in the head and neck region, affecting the nervous system. The wide range of therapeutic approaches demand the correct anatomical, morphological, and functional characterization of these lesions supported by imaging. Using a systematic search protocol in PubMed, Google Scholar, Ebsco, Redalyc, and SciELO, the authors extracted clinical studies, review articles, book chapters, and case reports that provided information about vascular cerebral malformations, in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 385,614 articles were grouped; using the inclusion and exclusion criteria, three of the authors independently selected 51 articles about five vascular cerebral malformations: venous malformation, brain capillary telangiectasia, brain cavernous angiomas, arteriovenous malformation, and leptomeningeal angiomatosis as part of Sturge–Weber syndrome. We described the next topics—“definition”, “etiology”, “pathophysiology”, and “treatment”—with a focus on the relationship with the imaging approach. We concluded that the correct anatomical, morphological, and functional characterization of cerebral vascular malformations by means of various imaging studies is highly relevant in determining the therapeutic approach, and that new lines of therapeutic approaches continue to depend on the imaging evaluation of these lesions.

“…An AVM nidus bears a resemblance to an HBM nodule due to dense collection of vessels [ 14 ]. Furthermore, HBMs histologically comprise numerous capillary channels, but an AVM nidus is made up of dysplastic arteries and veins, with the characteristic absence of an intervening capillary bed [ 15 ]. Because HBMs are associated with a coexisting feeding artery aneurysm, when hemorrhage is induced by HBMs, a cerebral aneurysm should also be considered [ 16 ].…”

Hemangioblastomas (HBMs) are rare vascular tumors commonly located in the posterior fossa of adults. A mid-50s patient presented with sudden unconsciousness. Computed tomography scans revealed acute hemorrhages around the posterior fossa, predominantly in the subarachnoid space. Digital subtraction angiography (DSA) revealed an 8-mm round lesion filled with contrast agent, fed by the C1 segmental artery of the left vertebral artery (VA), showing early venous drainage to the spinal cord and brainstem. Emergent embolization was attempted under suspicion of a ruptured dural arteriovenous fistula, resulting in parent artery occlusion due to feeder selection failure. Follow-up DSA after a month depicted a persistent aneurysm via collaterals from both VAs. Consequently, the decision was made to proceed with surgical intervention, leading to the resection of the lesion, confirming its diagnosis as a HBM through histological examination. This case underscores the potential for misdiagnosis when HBMs with an intratumoral shunt mimic vascular shunt lesions.

“…Although a rich vascular supply, mural nodule and cyst formation are frequently seen in the tumor of hemangioblastoma, other vascular anomalies near or adjacent to the tumor are not frequent. Several reports have been published as case studies in the literature [ 1 - 4 , 8 - 10 ] (Table 1 ).…”

“…Treatment with radiosurgery was often employed with a favorable tumor control for residual tumors. A few cases have been reported who developed hemangioblastoma in association with vascular anomalies [ 1 - 7 ]. We have encountered a case of hemangioblastoma associated with an arteriovenous malformation (AVM) near the tumor, though they were located separately below and above the tentorium.…”

Hemangioblastoma is well known as an essentially benign cystic and/or solid tumor classified WHO grade I, mainly originated in the posterior fossa. One of the characteristics of this tumor is very rich vasculature in and around the tumor. We have encountered a case of hemangioblastoma in association with a vascular anomaly near the tumor, though they were located separately by the tentorium. A vascular anomaly with arteriovenous (AV) shunting flow in the left occipital lobe was verified at angiography, which received a blood supply from left occipital artery and drained to occipital cortical veins. Successful removal of the cerebellar tumor and pathological diagnosis of hemangioblastoma was made. The second angiography in our hospital demonstrated the same vascular anomaly above the tentorium with feeding artery of posterior cerebral artery, a small nidus, and cortical draining veins, which were less obviously stained. Only the arteriovenous malformation (AVM) nidus in sigmoid vein was targeted for radiosurgery and 20 Gy at the margin was delivered. Since AV shunting was less remarkable on the second angiography than that on the first angiography may be because of a decreased vascular supply to the supratentorial AVM after surgical resection of the infratentorial hemangioblastoma and might indicate an indirect connection between the two lesions.
