We report a case of a giant cystic intradural schwannoma of the lumbosacral region in a 30-year-old man who presented with a 2-year history of non-specific lower back pain. Lateral radiographs demonstrated scalloping of the posterior wall of L5 and the upper sacrum. Magnetic resonance imaging revealed a 12x2.3-cm intradural multi-septated cystic lesion extending from L3 to S2 with predominant hypointense signal on T1-weighted images and a mixed signal on T2-weighted images. There was heterogeneous rim enhancement of the retrosacral portion of lesions following the administration of gadolinium contrast. The tumour was completely excised. Histological investigation confirmed the diagnosis of cystic schwannoma with alternating hypercellular (Antoni A) and hypocellular (Antoni B) areas in a fibrillar background. The patient had complete relief of symptoms and remained

We present a patient with spinal intradural tuberculosis in the absence of both vertebral and meningeal tuberculosis. Diagnosis was made based on intra-operative findings and was confirmed by histopathology. Early surgical decompression along with a combination of steroid and antitubercular therapy resulted in a good outcome. At 26-month follow-up, the patient regained bladder control and was able to walk with support. Clinical features, magnetic resonance imaging, and intra-operative findings are described. Pathology and the relevant literature are discussed.

A disc cyst is a rare entity with a clinical presentation that closely mimics an intervertebral disc herniation. Disc cysts are ventrally located, intraspinal, extradural cystic lesions that communicate with the parent intervertebral disc through a ruptured annulus. We present the clinical features, magnetic resonance imaging, intra-operative and histopathological findings of a variant of a lumbar intervertebral disc cyst in a 13-year-old girl who presented with a 6-month history of unilateral radiculopathy following an injury. Magnetic resonance imaging revealed a large posterocentral, fluid-filled cyst occupying the L5-S1 interspace and bulging into the spinal canal. The cyst was confined within an intact bulging annulus fibrosis and extended directly from the parent disc. The cyst was surgically decompressed, resulting in complete symptomatic relief.
