Giant Cystic Intradural Schwannoma in the Lumbosacral Region: A Case Report

Abstract

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

Totally cystic intradural schwannoma in thoracic region

“…could find only 10 cases with predominantly cystic changes reported in the literature. [7] Cystic schwannomas are most common in the lumbar region and occur rarely in the thoracic region. In a review of literature, we could find only two totally cystic schwannomas of the thoracic region reported in the English language.…”

Axillary Schwannoma with Extensive Cystic Degeneration

“…[3] Degenerative changes such as hemorrhage, calcification, and fibrosis are commonly seen in the schwannoma, but cystic changes are rare. [4] To the best of our knowledge, axillary schwannoma with such extensive cystic degeneration has not been reported so far. We report here, the first case of it diagnosed by the histopathological examination and confirmed with immunohistochemistry (IHC).…”

Cystic Giant Sacral Schwannoma Mimicking Aneurysmal Bone Cyst : A Case Report and Review of Literatures

“…The combination of giant sacral schwannoma with significant cystic component is extremely rare and only few cases have been reported in the literature13,14). We present a 54-year-old man with cystic giant sacral schwannoma mimicking aneurysmal bone cyst (ABC).…”
