Glial transformation of a DNET: About a case.

Dysembryoplastic neuroepithelial tumors (DNETs) are benign cortical tumors frequently associated with medically incurable focal epilepsy. These tumors occur most commonly in children. Given the fact that they rarely become malignant, the long-term prognosis in terms of mortality is excellent, however its similar appearance with other tumors of the central nervous system increases the potential for misdiagnosis and the risk of a pejorative clinical evolution.

A rare case of a median nerve schwannoma: Case report.

A median nerve schwannoma is an uncommon type of tumor that develops from Schwann cells in the peripheral nerves. We present a case report of a young prisoner with a rare median nerve schwannoma presenting as a swelling on the anterior aspect of the right wrist along the radial edge, with associated paresthesia and a positive Tinel's sign. The case was diagnosed using MRI which showed the target sign of biphasic contrast enhancement in both the mass's center and periphery as well as distinct encapsulation.

Neuroendocrine breast carcinoma: The importance of the correlation between histological and radiological findings.

Neuroendocrine breast carcinoma (NEBC) is an uncommon and malignant breast lesion. The absence of proper testing for this type of breast cancer carcinoma exacerbates this paucity. Additionally, only scant evidence of these tumors is present because of the repeated revisions in their diagnostic criteria throughout time.

Mandibular Metastasis in Neuroblastoma in a 3 Year-Old Child: A Case Report.

Neuroblastomas commonly metastasize to the cranium and orbit, although other facial bones were less implicated. In this report we present a 3 years old child with metastatic neuroblastoma to the mandible that presented with swollen right jaw. The first assessment of the head with computed tomography revealed soft tissue mass with permeative lytic changes of the osseous structures centered on the right mandible, as well as osteo-meningitis metastases.

Central nervous system manifestations of neurofibromatosis type 2: A case report.

Neurofibromatosis type 2 (phacomatosis) is a rare inherited autosomal dominant condition defined by the development of numerous central neuronal tumors. In addition to classic intracranial schwannomas, intracranial and spinal meningiomas, and intramedullary ependymomas, it can be associated with a few cutaneous abnormalities. In this report, we discuss the case of a 21-year-old female who was examined for persistent headache with cutaneous masses and bilateral hearing loss.

Kasabach-Merritt syndrome complicating a giant hemangioma of the liver: A case report.

Liver hemangiomas are the most common benign tumors of the liver with a prevalence of 1%-20% according to autopsy series. They can in some cases reach measurable sized. These giant hemangiomas can have fatal complications such as hemorrhaging, intraperitoneal rupture, mass of effect and Kasabach-Merritt syndrome.

Congenital bilateral perislyvian syndrome: A rare case report.

Congenital bilateral perisylvian syndrome, also known as bilateral periopercular syndrome or perisylvian polymicrogyria, is an exceptionally rare neurological disorder characterized by homogeneous clinicoradiological symptoms. There are consequently wide spectrums of clinical manifestations. In perisylvian syndrome.

Unruptured aneurysm with intramural thrombus is an unusual cause of spinal cord infarction: a case report.

Infarction of the spinal cord is a rather rare occurrence. Paraparesis or quadriparesis with vibration and proprioceptive senses sparing are symptoms of anterior cord syndrome. Ischemic anterior cord syndrome can result from an obstruction of the anterior spinal artery or the Adamkiewicz Artery.
