We report a rare case of spinal cystic schwannomas presenting as multiple ring-enhancing lesions in a young male. Surgical resection confirmed these unusual intradural tumors, offering insights into rare spinal cord pathologies.

Area of Science:

Neurology
Neurosurgery
Pathology

Background:

Intradural spinal lesions can present with various neurological deficits.
Ring-enhancing lesions on MRI suggest differential diagnoses including tumors, infections, and inflammatory conditions.
Cystic schwannomas are rare tumors, particularly within the intradural spinal compartment.

Purpose of the Study:

To present a unique case of intradural multiple ring-enhancing lesions.
To discuss the diagnostic challenges and differential considerations for such spinal findings.
To highlight the histological confirmation and surgical management of cystic schwannomas.

Main Methods:

Case presentation of a 20-year-old male with progressive spastic paraparesis.
Magnetic Resonance Imaging (MRI) of the thoracolumbar spine to identify lesions.

Surgical resection of the identified intradural lesions.

Histopathological examination for definitive diagnosis.

Main Results:

MRI revealed two distinct ring-enhancing lesions at the T12 and L1 vertebral levels.
Surgical resection was performed with a successful and uneventful outcome.
Histological analysis confirmed the lesions as cystic schwannomas.

Conclusions:

Cystic schwannomas should be considered in the differential diagnosis of intradural, ring-enhancing spinal lesions, even in young patients.
Multimodality imaging and surgical pathology are crucial for accurate diagnosis and management.
Complete surgical resection can lead to favorable outcomes for patients with symptomatic cystic schwannomas.
