Parasagittal cystic meningioma mimicking hemangioblastoma: A case report

Abstract

Background: Cystic meningioma is a rare variety with similar histological profiles like the solid tumors. It has been documented in both supratentorial and infratentorial compartments presenting radiologically as a large cyst with mural nodule mimicking hemangioblastoma. Case Description: We managed a middle-aged woman who presented with recurrent seizures and brain MRI revealed left frontal cystic parasagittal tumor with mural nodule. She had left frontal awake craniotomy and gross total tumor excision. Histology confirmed meningothelial meningioma. Conclusion: Cystic meningioma is rare but should be high in differentials of cystic intracranial tumor with dural based nodules. Awake craniotomy is possible for the excision of parasagittal tumor most especially when it is frontal in location.

Awake Craniotomy in Africa: A Scoping Review of Literature and Proposed Solutions to Tackle Challenges

“…[41][42][43][44][45][46][47] All studies, except 4, reported AC on tumors only (78.9%). 22,23,26,29,31,32,[34][35][36][37][38][39][40] 1 study (5.3%) reported AC in epilepsy, 25 whereas 3 studies (15.8%) reported other surgical indications in addition to tumor 24,30,33 (Supplementary Table 3, http://links.lww.com/NEU/D712).…”

“…Sixteen studies (84.2%) provided information on operation time. [22][23][24][25][26][27][28][30][31][32][34][35][36][37]39,40 The longest mean operation time was more than 237 minutes, 24 whereas the shortest operation time was 1 hour 33 (Supplementary Table 3, http://links.lww.com/NEU/D712).…”

“…Thirteen studies (68.4%) specified the preoperative diagnostic imaging methods for localizing the lesions. 22,26,[28][29][30][31][33][34][35][36][37]39,40 MRI was the most common method used in 8 studies (42.1%) for preoperative localization, 26,31,[34][35][36][37]39,40 whereas computerized tomography (CT) and MRI were used in 4 studies (21.1%). 22,28,30,33 (Supplementary Table 4, http://links.lww.com/NEU/D713).…”

“…Elbakry et al 25 had the largest sample size, with 65 patients (16.4%), whereas the smallest sample size was in case-reports with 1 patient (0.25%) each. [34][35][36]38,40 Apart from 2 studies (10.5%) that had a mixture of adults and pediatric patients, 28,30 and 1 study (5.26%) that was on a child, 40 all other studies (84.2%) had adult patient populations. [22][23][24][25][26][27]29,[31][32][33][34][35][36][37][38][39] The youngest reported AC patient was 11 years old, 40 with the oldest being 92 years old, 33 demonstrating the accessibility of AC for a wide age range.…”

Relative to adults undergoing operations, AC is less widely used in children, likely due to case complexity, a higher risk of postoperative neurocognitive deficits, and a lower frequency of lesions in eloquent areas 51,52 (Table 1).…”
