The clinical data and imaging studies of 12 patients with intramedullary metastases were reviewed retrospectively to see if these lesions had a typical radiographic appearance and to determine the sensitivity of the various radiologic examinations. The lesions were identified antemortem by either myelography, CT, MR, and/or intraoperative spinal sonography (IOSS). Final diagnosis was based on b...

Cavernous hemangiomas affect mainly the brain and infrequently they are located in the intramedullary space. Spinal epidural cavernous haemangiomas are extremely rare and are mainly located to the cervico-thoracic spine. It is infrequently considered in the differential diagnosis of spinal epidural masses. We report a rare case of a cavernous haemangioma confined to the lumbar spinal epidural s...

INTRODUCTION We report three cases of demyelinating disease with tumor-like presentation. This information is particularly important to both neurosurgeons and neurologists who should be aware that inflammatory demyelinating diseases can present as a mass lesion, which is indistinguishable from a tumor, both clinically and radiologically, especially when there is no evidence of temporal dissemin...

A 23-year-old Brazilian man, a farmer in a rural area of Minas Gerais State, complained of an 8-month history of neck pain and upper-limb weakness. Flaccid tetraparesis, global hyperreflexia, and pyramidal signs were present. Cranial CT and brain MRI were normal. Spinal cord MRI showed an intramedullary tumoral lesion, extending from C3 to C5 vertebral bodies, with a cystic appearance (figure 1...

Neurocysticercosis is commonly seen intracranially and its incidence in the spinal cord is very low. Among spine dorsal region is more common due to more blood flow in this region and it is usually associated with lesion at other sites. The intramedullary location is rarer than extramedullary. Hence, solitary intramedullary cervical spine cysticercosis (ICC) is extremely rare entity. Only a han...

Introduction ▼ Primary spinal tumors are relatively rare lesions, representing 4–8 % of all central nervous system tumors (Duong LM et al. Cancer 2012; 118: 4220–4227). Magnetic resonance imaging (MRI) represents the gold standard for the diagnosis and assessment of intradural tumors. Nevertheless, sometimes MRI may not accurately differentiate between intramedullary and extramedullary tumors. ...

Fibrocartilaginous dysplasia (FCD) has occasionally led to a misdiagnosis and wrong decision which can significantly alter the outcome of the patients. A 9-yr-old boy presented with pain on his left distal thigh for 6 months without any trauma history. Initial radiographs showed moth eaten both osteolytic and osteosclerotic lesions and biopsy findings showed that the lesion revealed many irregu...

Abstract The authors present two cases of von Hippel-Lindau (VHL) disease-associated hemangioblastomas in the central nervous system (CNS) treated with newly-approved HIF-2α inhibitor, belzutifan. first case is that a 31-year-old female confirmed pathogenic germline VHL mutation who presented multiple diagnosed at 25 years age. patient was managed surgically resection three posterior fossa but ...

Epidermoid cysts are benign tumors originating from ectoderm remnants. Most epidermoid cyst cases are intracranial. Spinal epidermoid cysts are uncommon and most of the reported cases are in the thoracic and lumbar spine. Occurrence of intramedullary epidermoid cysts in the cervical spine is extremely rare. An 18-year-old male with a giant intramedullary tumor extending from the...
