“…The incidence of visible cysts in meningiomas is approximately 1.6%–11.7% ( 6 ). In addition to the previously noted microcysts, which are not observed on imaging, microcystic meningiomas also can have relatively large, visible intratumoral cysts or cystic change ( 7 ). These radiologically visible cysts can contribute to the characteristic reticular enhancement of meningiomas ( 8 ).…”

“…Two patterns of contrast enhancement in microcystic meningiomas have been described. The first and most common is homogeneous avid enhancement similar to that of ordinary meningioma ( 7 ) which presumably occurs in the absence of larger, visible cysts. A second, less frequent pattern of marginal and reticular enhancement is seen in approximately 27% patients ( 7 ).…”

A second, less frequent pattern of marginal and reticular enhancement is seen in approximately 27% patients ( 7 ). This pattern is thought to be due to variably sized, larger cysts measuring several millimeters, which are not enhanced on the MRI contrasted with strong enhancement of its solid portion.…”

Imaging Features and Pathological Correlation in Mixed Microcystic and Angiomatous Meningioma: A Case Report

Meningiomas are the most common intracranial tumors. However, microcystic and angiomatous meningiomas are very rare subtypes that present unusual imaging findings. Hence, radiological diagnosis of these tumors can be challenging. We herein describe a case of mixed angiomatous and microcystic meningioma in an 81-year-old male. MRI revealed an extra-axial mass with high T2 signal intensity, measuring 1.5 cm in diameter, with multiple tiny intralesional cysts and entrapped peritumoral cyst formation. After tumor resection, a histopathological diagnosis of mixed angiomatous and microcystic meningioma was made.

“…A maioria dos pacientes apresenta sintomatologia progressiva e lenta como resultado da compressão das estruturas cerebrais (JACOBO et al, 2020). Em alguns casos, o aumento rápido do tumor pode levar a uma deterioração mais rápida do estado geral do paciente, ocasionando assim uma urgência ou mesmo emergência cirúrgica (JACOBO et al, 2020).…”

“…Microcystic meningiomas (MCMs) are a distinct histological variant of meningioma and are associated with atypical imaging appearances and therefore present with diagnostic challenges [120]. These tumours account for only 1.6% of intracranial meningiomas [117,120]. Cells have elongated processes and loose myxoid background [121].…”

Central nervous system (CNS) tumours refer to tumours that occur in the tissues of the brain and/or spinal cord. These tumours arise as a result of abnormal growth of cells and may begin in different parts of the brain or spinal cord. There are many types of CNS tumours, which are further divided into subtypes. Despite decades of research conducted, CNS tumours remain among the deadliest of all cancers. It is most often challenging to treat these tumours, due to the risks involved, and biological characteristics associated with them. The classification, grading, and characterisation of CNS tumour plays a pivotal role in the management thereof. The current review provides an overview of CNS tumours, classification, grading and treatment, as well as their characterisation with specific focus on gliomas, ependymomas, oligodendrogliomas, meningiomas, medulloblastomas, schwannomas, gangliogliomas, and craniopharyngiomas.
