Unusual presentation of multiple nerve entrapment: a case report.

Cubital tunnel syndrome is the most common form of ulnar nerve entrapment and the second most common entrapment neuropathy of the upper extremity after carpal tunnel syndrome. However, bilateral compressive ulnar neuropathy is a rare condition. Electro diagnostic studies are a valid and reliable means of confirming the diagnosis

Natural Course of Myxopapillary Ependymoma: Unusual Case Report and Review of Literature.

BACKGROUND: Spinal cord ependymomas are the most frequent primary intramedullary tumors of the cord in middle age (40-60 years of age). Myxopapillary ependymomas are low-incidence tumors and occur in the cauda equina and conus medullaris. They are typically described as fleshy, sausage-shaped, vascular lesions. CASE DESCRIPTION: In this report, we present a 36-year-old woman who was seen in another hospital with complaints of back pain radiating into both legs 5 years ago. Magnetic resonance imaging (MRI) examinations revealed a lesion releated to the spinal cord. At that point, the patient refused the proposed surgical treatment. Five years later, the patient was referred to our clinic with advancement of the complaint to paraparesis. The new MRI showed an intradural mass at the level of T11 and S1. We performed a total intradural tumor resection. Histopathologic examination revealed a myxopapillary ependymoma. CONCLUSIONS: Myxopapillary ependymomas grow slowly and are well defined by MRI. Advancements in radiologic technology and surgical equipment have allowed this tumor type to be treated successfully. Unfortunately, if untreated, these lesions have poor prognosis and result in clinical symptoms such as paraparesis. Surgical treatment of these lesions using total resection was performed total resection and was associated with an excellent postoperative outcome. We highlight the natural course of myxopapillary ependymomas

Melanotic neuroectodermal tumor of infancy in the skull: a case report.

Melanotic neuroectodermal tumor of infancy (MNTI) is a rarely occurring neoplasm of neural crest origin, appearing in children during the first year of life. MNTI is a benign tumor but is nonetheless locally aggressive; it usually originates from the maxilla and the mandible. Recognition of the diagnostic features of MNTI is important, so that it may be differentiated from benign lesions (dermoid or epidermoid cysts, vascular lesions) as well as from malignant lesions such as small round cell tumors. We present a case of a 2-month-old infant who developed right retroauricular swelling with extension through the calvarium and into the central nervous system. The tumor was totally resected. Aggressive benign or malignant lesions of the calvarium may entail dural infiltration and brain involvement, as in our case. Early diagnosis and surgery are thus mandatory for benign or malignant tumors of the calvarium
