Authors present a case of a 57-year-old woman with primary spinal cord malignant melanoma. Intramedullary localization of primary melanoma is extremely rare. The patient presented neurological deficits such as lower limbs paresis and sensory loss. MRI examination showed intramedullar tumor located on the Th10 vertebra level. Surgical treatment with total removal of tumor was performed. Histopat...

We report a case of ganglioneuroblastoma of the spinal cord in a 42-year-old man. MR examination was nonspecific, and the diagnosis was made from histologic findings. The MR picture was that of an intramedullary, mainly solid tumor with a central necrotic or cystic portion. The clinical picture and course were also nonspecific.

Abstract Background Vascular malformation of the spine accounted for 3–4% all intradural lesions. Spinal arteriovenous (AVM) is often missed because overlapping symptoms with other pathology and ambiguous imaging. Here, we report a conus medullary AVM that mimics intramedullary tumours either from clinical findings or MR Case presentation We 24-year-old man left foot monoparesis, paresthesia, i...

Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here, we clarify the origin of wetting hysteresis for a liquid front advancing or receding across an isolated defect of nanometric size. Various kinds of chemical and topographical nanodefects, which represent salient features of actual heterogeneous surfaces, are investigated. The most pr...

The aim of the present study was to develop an animal model of pulmonary fat embolism (PFE) caused by femoral intramedullary procedures, and to investigate the initial changes in the hemodynamics, cytokines and risk factors of PFE. Sixteen dogs were randomly divided into two groups: Group A (intramedullary reaming and bone cement injection, n=8) and Group B (surgical approach without opening th...

Two cases of intramedullary paracoccidioidomycosis are reported. Paracoccidioidomycosis is a systemic disease that involves the buccopharyngeal mucosa, lungs lymph nodes and viscera and infrequently the central nervous system. Localization in the spinal cord is rare. Case 1: a 55-year old male admitted with crural pararesis, tactile/painful hypesthesia and sphincter disturbances of 15 days dura...

BACKGROUND Resection guided by 5-aminolevulinic acid (5-ALA) fluorescence has proved to be useful in intracranial glioma surgery. However, the effects of 5-ALA on spinal cord tumors remain unknown. OBJECTIVE To evaluate the usefulness of 5-ALA fluorescence-guided resection of intramedullary ependymoma for achieving maximum tumor resection. METHODS This study included 10 patients who underwe...

Abstract Purpose Most of the intramedullary spinal cord lesions have a component insidious myelopathic changes at time diagnosis. Among lesions, neoplasms are rare (25%). They represent 4 to 10% all central nervous system tumors. But due involvement tracts, they associated with significant neurological symptoms. Their imaging features can help early diagnosis and predict prognosis. We aim narro...

A 52-year-old man with a seven-year history of progressive weakness, gait problems, and pain in his extremities presented with subacute worsening of his symptoms. Examination revealed weakness in all four extremities, increased tone, hyperreflexia, and sensory deficits. MRI of the cervical spine showed an area of signal abnormality and abnormal enhancement within the cervical cord at the C5-C6 ...
