AIM To determine the role of intraoperative ultrasonography (IOUSG) in the surgical management of patients with intradural spinal tumors. MATERIAL AND METHODS Twenty-six patients with intradural spinal cord tumors were surgically treated under intraoperative ultrasonographic guidance between January 2007 and May 2011. Guidance with IOUSG was used in 26 patients, of which 14 fourteen had extra...

solitary plasmacytoma of bone is a rare malignant tumor mostly involving the axial skeleton. the tumor occurs in middle- aged or elderly people (mean age: 55 years) and has a high risk of progression to multiple myeloma. radiotherapy is the preferred treatment for this disease. we report a case of recurrent solitary plasmacytoma of the fourth lumbar vertebra in a 35-year-old male. the patient s...

ependymomas accounts for about 2%–6% of cns and 60%–70% of spinal cord tumors. several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. in spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. this report presents a case of giant cell ependymoma...

Granular cell tumors (GrCTs) of the spinal cord are rare benign tumors with a high rate of local recurrence. Only 6 cases of spinal GrCTs have been reported. GrCT is difficult to distinguish from other benign tumors such as schwannoma using imaging. A radiological "speckled dots" sign may be a useful differentiating feature of GrCT based upon experience with two cases and a review of the litera...

Dermal sinus tracts have been reported all along the midline neuroaxis, with the majority being located in lumbar and sacral areas. They are usually associated with split cord malformations, tethered cord and inclusion tumors (dermoid, epidermoid, teratoma). Dermal sinus tracts with concomitant dermoid or epidermoid tumors are frequently associated with recurrent meningitis, but spinal subdural...

Two patients with longitudinally extensive myelopathy were initially biopsied for suspected spinal cord tumors. Both patients were later diagnosed with neuromyelitis optica spectrum disorders (NMOSD) supported by their AQP4-seropositivity. Pathological review of both biopsies revealed demyelinated lesions with thickened vessel walls and tissue rarefaction. Immunohistochemical staining demonstra...

Intradural intramedullary mixed type hemangioma is a rare histotype of primary spinal cord tumors, though it can carry a severe clinical burden leading to limb dysfunction or motor and sensory disturbances. Timely intervention with radical resection is the hallmark of treatment but achieving it is not an easy task even for experienced neurosurgeons. We herein present an exemplificative case pre...

The incidence of spinal cord astrocytomas (SCAs) is very low and therefore, management these tumors are challenging due to this paucity. In report, a patient with recurrent SCA was successfully treated bevacizumab after failing previous therapies including radiotherapy (RT) temozolomide (TMZ). Bevacizumab an angiogenesis inhibitor that widely used in high grade gliomas shows promise for SCAs bu...

PURPOSE Primary spinal cord and appendage tumors (PSCAT) originating from the spinal cord, spinal meninges, and cauda equina are uncommon. Worldwide, population-based cancer registry data are mostly based on malignant tumors only, which means few data are available on PSCATs, including non-malignant tumors. Therefore, the objective of this study was to provide information regarding the incidenc...
