“…2) (Type B1), while the peritumoural cyst was surrounded by a thin rim of enhancing tumour in addition to the enhancing tumour nodule in cases 2 and 8 ( Fig. 3) (Type B2) as was previously noted by Lake [12]. All peritumoural cysts contained xanthochromic fluid of variable density [3,7,12,16,18].…”

“…Lake et al [12] reported the third recurrence of a cystic parieto-occipital meningioma in a 43-year-old female without evidence of malignancy or structural changes. The similarity of their anaplastic meningioma to haemangiopericytoma may explain the cystic changes.…”

“…At operation extra-axial tumour surrounded by a large cyst containing dark brown; xanthochronic or clear fluid with variable densities and protein content, may be found [7,9,12,16,21] representing 4 main types of cysts as described by Nauta et aL [21].…”

Meningiomas are usually solid tumours. Cystic changes in meningiomas are rare. These cysts may occur extratumoural, peritumoural or intratumoural. Diagnostic difficulties arise in cases of cystic meningiomas. Nine cases of cystic meningiomas were operated on in the past 6 years at the department of neurosurgery University of Alexandra. The mean age of patients was 46.2 years. Male to female ratio was 1/2. Less oedema was observed in extratumoural cysts, and more oedema in intratumoural cysts. The fluid contained was dark brown or dirty yellow in intratumoural cysts (type C), xanthochromic in peritumoural cysts surrounded by tumour tissue (Type B), or clear fluid in extratumoural cysts (Type A). Based on these two observations it is proposed that the cyst fluid and peritumoral oedema may represent variable degrees of degeneration or secretion by tumour cells. Pre-operatively diagnostic criteria are presented.

“…Our case 3 appears to conform to this configuration (Figs. 8 and 9), as do several reported cases, including the case of Lake et al (1973) and the first of the three cases presented by Henry et al (1974). In the type 3 configuration the cyst again appears to be peripheral, and indeed actually lies within the adjacent brain rather than within the tumour itself.…”

Key Clinical MessageMeningiomas present diverse clinical and radiological characteristics, with cystic formations constituting a lesser subset but posing significant diagnostic hurdles. We explore the complexities of cystic meningiomas through a distinctive case, highlighting the challenges in diagnosis and management due to their variable presentations. A 54‐year‐old female from Bengaluru, Karnataka, initially presented with transient memory disturbances. Brain MRI revealed a sizable left frontal cystic lesion exerting a mass effect and midline shift. However, rapid neurological decline led to an urgent surgical intervention via decompressive craniectomy unveiling unique intraoperative findings and with subsequent histopathological documentation of a Grade WHO 1 cystic meningioma. Cystic meningiomas present intricate diagnostic challenges resembling other intracranial lesions. Various classification systems attempt to categorize these tumors based on their imaging and histopathological characteristics. Despite this, atypical clinical manifestations often lead to misdiagnoses, necessitating a comprehensive approach to differential diagnosis. Further research is crucial to unravel the mechanisms underlying these tumors' cystic changes for improved diagnostic accuracy and tailored therapeutic interventions.

Abstract: ✓ Cystic meningiomas are rare variants of the usually solid tumor. A case is presented, together with a discussion of the relationship to cystic changes in the histologically similar angioblastic meningiomas and posterior fossa hemangioblastomas.
