TORRECILLAS-CABRERA, María del Mar; MOYA-SANCHEZ, Elena; GARCIA-ESPINOSA, Jade  and  PASTOR-RULL, Jorge. How To Recognize Intraosseous Meningioma: Etiology And Imaging Findings. Rev Ecuat Neurol [online]. 2021, vol.30, n.1, pp.210-212. ISSN 2631-2581.

Meningiomas are the most common primary brain tumors. Primary intraosseous meningioma is a rare extradural meningioma subtype. They are usually asymptomatic but may cause proptosis or neurological symptoms depending on size and location. The most common finding in imaging tests is hyperostosis although a lytic or even mixed pattern can also be observed, so it should be considered in the differential diagnosis of cranial sclerotic bone tumors. Although most are benign, they are more likely to develop malignancy than intradural meningiomas. Imaging techniques (CT and MRI) are very useful in preoperative diagnosis and evaluation of adjacent anatomical structures. Surgical resection followed by cranial reconstruction is the treatment of choice.
