Giant erosive spinal schwannomas can be distinguished from other spinal schwannomas by its growth in myofascial planes and vertebral body erosion. Therapeutic radical tumour excision without neurologic deterioration is possible in the management. Prognosis is good after total tumour removal. In this article, it is aimed to report six patients who were diagnosed as giant erosive spinal schwannomas between 2001 and 2004 according to the criteria of Sridhar et al. Three of the patients were male and three female with the age range of 16-63 (mean age 39.7). Three of the tumours were located in the cervical region, one in the lumbar region, one in the thoracic region and one in the sacral region. Total excision of the tumours was achieved in four patients. However, one additional operation was required in two patients. Follow-up periods ranged from 6 weeks to 7 years (mean follow-up 51 months). Four patients had a good clinical outcome and there were no radiologic signs of instability or recurrence. Our experience and other published literature suggest that giant erosive spinal schwannoma has significant features such as local invasive nature together with vertebral body erosion and large size but benign histology, long duration for clinical presentation, common preoperative misdiagnosis and good prognosis after total excision. These tumours rarely need spinal instrumentation because the disc capsule and ligaments remain intact even if the pedicle and posterior elements are compromised.

“…This is typically anteriorly into the pelvic cavity [3,5,9,11,12] but can be posteriorly [2] or combined [6,8]. In contrast, giant presacral schwannomas (GPSS), as illustrated in this small series and a recent case report [12], presumably arise from a peripheral nerve in or adjacent to an anterior sacral foramen.…”

“…One to 5% of spinal axis schwannomas arise in the sacrum [2] and frequently grow to considerable size before detection; hence, the term giant sacral schwannoma (GSS). To date, less than 40 cases of GSS have been described, often single case reports, predominantly in the orthopaedic and neurosurgical literature [2,3,4,5,6,7,8,9,10,11,12]. The largest published series of 13 cases of GSS collected over 33 years predated the routine use of MR imaging [3].…”

Benign giant sacral schwannoma is an uncommon cause of destruction of the sacrum. This report details four cases of a variant of this condition called giant presacral schwannoma (GPSS). On MR imaging the features are of a large, well-defined presacral soft tissue mass, arising just to one side of the midline with minor involvement of the bone. The typical MR features of a benign peripheral nerve sheath tumour are not seen. The tumours appear heterogeneous due to long-standing degeneration. Biopsy is advocated as the appearances of GPSS can be similar to a malignant peripheral nerve sheath tumour (malignant schwannoma).

“…There may also be multiple processes, for instance intradural or extradural cysts and tumors (mainly schwannomas), adult tethered cord syndrome, spinal epidural abscesses and hematomas, facet syndrome, lumbosacral deformities and instabilities. 5,7,[11][12][13][14] The pain pattern, and the presence or abscence of accompanying symptoms, are the most important components of the differential diagnosis.…”
