Progressive visual and hearing loss as looming manifestations of spinal meningeal melanocytoma

چکیده
The term "meningeal melanocytoma" was first used by Limas and Tio in 1972 to describe a benign tumor of melanocytic origin arising from the leptomeninges [2]. In the World Health Organization classification of brain tumor, meningeal melanocytoma represents a subgroup of primary melanocytic lesion, which most frequently originates from the leptomeninges of posterior fossa or along the spinal cord [3]. The melanocytic lesion of the CNS may also be a primary or metastatic malignant melanoma, and it is important to differentiate melanocytoma from these malignant tumors [2,4]. There are also other differential diagnoses for melanocytoma such as melanotic meningioma or melanotic schwanoma [5]. Meningeal melanocytoma usually produces a slowly progressive mass effect on adjacent neural structures [4]. Coincident superficial Case Report

Progressive visual and hearing loss as looming manifestations of spinal meningeal melanocytoma
Abstract Meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal melanocytes. The locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. The manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that c...
متن کاملUnusual Tonsillar Herniation in Meningeal Melanocytoma: A Case Report
Meningeal melanocytoma is a primary melanocytic neoplasm with certain MR and immunohistochemical characteristics worthy to note. In a 38-year-old man with a complaint of headache for a couple of years and recently added nausea, vomiting, diplopia, progressive visual blurring and hearing loss, magnetic resonance imaging (MRI) was remarkable for T1 shortening of leptomeninges and certain nodules ...
متن کاملIntramedullary spinal melanocytoma
Meningeal melanocytoma is a benign lesion arising from leptomeningeal melanocytes that at times can mimic its malignant counterpart, melanoma. Lesions of the spine usually occur in extramedullary locations and present with spinal cord compression symptoms. Because most reported spinal cases occur in the thoracic region, these symptoms usually include lower extremity weakness or numbness. The au...
متن کاملPrimary meningeal melanocytoma.
Meningeal melanocytoma is an uncommon benign pigmented primary lesion that has to be distinguished as a pathological entity separate from other benign melanin containing tumours as well as its overtly malignant counterpart, melanoma. In the present study, a 58 year old lady presented with bilateral sensory and motor symptoms in the lower limbs. The MRI scan showed a dumb-bell shaped lesion in t...
متن کاملMR of spinal meningeal melanocytoma.
We report an unusual case of meningeal melanocytoma, a rare pigmented lesion of the leptomeninges, that occurred within the leptomeninges of the thoracic spinal canal. The lesion showed increased signal intensity on T1-weighted MR images relative to gray matter, was isointense with gray matter on T2-weighted images, and enhanced mildly but homogeneously after administration of contrast material.
