We present a case of an intramedullary melanotic schwannoma (IMS) of the thoracic spinal cord. To our knowledge, this is the seventh reported case of an IMS of the central nervous system. Schwannomas are benign nerve sheath tumors of neural crest origin composed entirely of well differentiated Schwann cells that typically occur in peripheral nerves. Both the intramedullary location and the mela...

Hemangioblastomas represent cca. 1 2,5% of all the intracranial tumours and only 2 -3% at the level of the spinal cord. The symptomatology, usually insidious, is directly proportional with the size of the tumour. The native magnetic resonance imaging (MRI) scan and the use of a contrast agent is the investigation of choice for diagnosing intramedullary tumours. Authors report the case of a 51 y...

Fibrous dysplasia (FD) is a common benign intramedullary lesion of the skeleton characterized by proliferation of fibro-osseous tissue. It is viewed as a developmental abnormality that is typically seen in adolescents and young adults. The lesion is usually asymptomatic and many times discovered as an incidental finding. Exophytic FD is an extremely rare variant that has to be differentiated fr...

BACKGROUND A case of primary intramedullary glioblastoma occurring at conus medullaris is presented, which was initially undetected and misdiagnosed as L1 through L2 disk herniation. CASE DESCRIPTION After the performance of L1 through L2 discectomy, the patient's initial painful symptom did not subside. The patient then developed a progressive paraparesis. The outside surgeons only predicted...

In this report, the authors present a 14-year-old male patient admitted with progressive paraparesis and urinary incontinence that developed in a 3-month period. Thoracolumbar MRI revealed an intramedullary lesion starting from the level of the T10 vertebra and extending to fill the sacral spinal canal. Based on the radiological findings an intramedullary tumor was suspected. Exploratory operat...

Eosinophilic myelitis (EM) or atopic myelitis is a rare disease characterized by a myelitic condition in the spinal cord combined with allergic process. This disease has specific features of elevated serum IgE level, active reaction to mite specific antigen and stepwise progression of mostly the sensory symptoms. Toxocariasis can be related with a form of EM. This report describes two cases of ...

Intramedullary spinal cord metastasis is very rare. In this study, we present the case of a 32-year-old male patient with a 2-month history of bilateral lower extremity weakness. Initial magnetic resonance imaging of the dorsal spine showed abnormal thickening of the dorsal spinal cord at the level of the T1-2 bodies. FDG-PET/CT images revealed a hypermetabolic lesion in the spinal cord at this...

Intraspinal epidermoid cyst is a rare tumor. The incidence in adults is lesser than 1% and in children lesser than 3%. Epidermoid cyst is predominantly seen at the dorsal spinal level. A large percentage of epidermoid cysts are intradural extramedullary. Intramedullary epidermal cysts are rarer, with about 70 cases reported in the literature. These may be congenital or acquired with known assoc...

We report a case of a non-infantile primary intramedullary spinal cord desmoplastic astrocytoma in an 18-year-old girl who presented with spastic paraparesis. The patient had been unable to run for 1 year. Magnetic resonance imaging of her spine showed an intramedullary solid and cystic heterogeneously enhancing lesion located at T7-T8 level. Partial excision was performed. Histology revealed a...

Osteoid osteoma is a small benign bone tumor usually affects adolescents and young adults. Although this tumor mainly affects the shafts of long bones there have been several reports of subperiosteal and intramedullary involvement .Complete surgical excision is the classic treatment of choice for patients with osteoid osteoma. Despite the small size of the tumor, the operative procedure for its...
