SUMMARY: Intracranial lipomas are rare lesions. Intracranial lipoma associated with a subcutaneous lipoma is extremely rare. Various vascular abnormalities have been described in association with intracranial lipoma, including distension, kinking, or narrowing of arteries and veins; arteriovenous malformation; and aneurysm. To our knowledge, association of sagittal sinus fenestration, falcine sinus, and absent straight sinus with intraextracranial lipoma has not been reported before. We report the imaging findings of an infant with interhemispheric and subcutaneous lipoma associated with falcine sinus and sagittal sinus fenestration.

“…23 Existem relatos de lipomas em fissura silviana 24,25 e de um caso de lipoma em fissura silviana associado a aneurisma de artéria cerebral média. 26 Nosso estudo apresenta o primeiro caso de AGL em fissura silviana associado a aneurisma da artéria cerebral média.…”

“…17 Futami et al sugerem que lipomas intracranianos localizados em fissura silviana tem origem malformativa advinda da persistência e diferenciação anormal da meninge primitiva e que os aneurismas associados poderiam dever-se a deficiência estrutural congênita que ocorreria ao mesmo tempo que a formação dos lipomas. 26 O diagnóstico dos AGL intracranianos é feito através de exames de imagem. À TC esses tumores podem apresentar-se como lesões hipodensas, homogêneas ou heterogêneas de acordo com a relação de tecido gorduroso e vascular em seu interior, com captação do meio de contraste.…”

IntroduçãoLipomas são tumores benignos do tecido adiposo, sendo o mais comum dentre os tumores de partes moles na vida adulta. O subtipo mais frequente é o lipoma convencional, que se caracteriza por uma massa bem encapsulada de adipócitos de tamanhos variados, localizando-se principalmente nas extremidades proximais e tronco. Os Palavras-Chave ResumoAngiolipomas são neoplasias benignas compostas por adipócitos maduros e proliferação vascular angiomatosa de rara ocorrência no Sistema Nervoso Central. É relatado o caso de angiolipoma em cisterna silviana adjacente a aneurisma sacular de artéria cerebral média. São discutidas as características imagenológicas do tumor e a possibilidade de uma origem comum com lesões vasculares intracranianas. Este é o primeiro caso relatado de angiolipoma intracraniano associado a aneurisma de artéria cerebral média. AbstractAngiolipomas are benign neoplasms composed of mature fat cells and vascular angiomatous proliferation of rare incidence in Central Nervous System.It's related a case of angiolipoma in Sylvian fissure associated with cerebral saccular aneurysm of medial cerebral artery. Imagenologic characteristics of the tumor and a possible common origin with intracranial vascular lesions are discussed. This is the first reported case of intracranial angiolipoma involving medial cerebral artery aneurysm.

“…The possibility that mesodermal dysplasia is involved in the pathogenesis of such aneurysms has been suggested [90,101,102]. Similarly, aneurysms associated with lipomas have been attributed to a developmental defect in the meninx primitiva, which promotes the formation of both lesions [103]. Primary intracranial neoplasms have rarely been directly implicated in the pathogenesis of IAAs when the aneurysm is found encased in tumor [104,105].…”

Intracranial arterial aneurysms are an important cause of hemorrhagic stroke during the first two decades of life. In the pediatric population, intracranial arterial aneurysms have a diverse etiological spectrum. The clinical course, response to treatment and long-term prognosis correlate strongly with the mechanism of lesion pathogenesis. A variety of phenotypes have been characterized, having variably overlapping features and differentiated according to the mechanism of pathogenesis: (1) idiopathic, (2) traumatic, (3) infectious, (4) flow related, (5) oncotic, (6) non-infectious inflammatory, (7) arteriopathic and (8) familial. The purpose of this report is to review intracranial aneurysmal disease in the pediatric population. We discuss contemporary approaches to diagnostic evaluation and clinical management, emphasizing interventional strategies and recent advances.
