MRI imaging and intraoperaive findings in Case 2. (a,d) T1W axial and sagittal image showing hypointense lesion; (b,e) T2W axial and sagittal image showing hyperintense lesion; (c) Contrast-enhanced T1W axial showing thin rim enhancement; characteristic finding of uniloculated cystic spinal schwannoma. (f,g) Intraoperative findings showing cystic lesion with translucent, thin wall. (h) Specimen ex vivo

The cyst exhibited intensity similar to cerebrospinal fluid (CSF) on T1-weighted image (T1WI) and T2-weighted image (t2WI) [Figure 2a, b, d, and e], with rim-enhancement on contrast administration [Figure 2c]. The patient underwent L2-L4 laminectomy and total excision of the lesion. Intraoperatively, on opening the dura, a cystic lesion with translucent walls was seen displacing the roots on either side [Figure 2f]. Cyst was decompressed and lesion was excised maintaining the arachnoid plane [Figure 2g and h].

MRI findings in case 6. T2W Sagittal (a); contrast-enhanced T1W Sagittal (b); and contrast-enhanced T1W Coronal (c) MR images showing giant multi-loculated cystic schwannoma with a thin solid component along its cranial aspect (arrows). Preoperative differentials were intradural spinal abscess and cystic schwannoma. Intraoperative findings and histopathology confirmed cystic schwannoma

T1WI and T2WI [Figure 5a], extending from the D10 vertebral level to the L5 vertebral level. The rim as well as the septations showed intense contrast enhancement [Figure 5b and c].
