Spinal epidermoid cyst associated with limited dorsal myeloschisis.

Background: Epidermoid cysts (ECs) are rare benign tumors arising from epidermal cells, associated with congenital abnormalities or acquired through trauma, surgery, or lumbar punctures. They represent <1% of all intraspinal tumors and may be associated with limited dorsal myeloschisis (LDM).

Case Description: A 7-year-old neurologically intact male had a dorsal skin mass since birth located posteriorly in the midline of the inferior thoracic spine.

[Fourth ventricule epidermoid cyst: about a case].

Epidermoid cysts are rare benign tumors developed by ectodermic inclusions. They are usually located at the level of the pontocerebellar angle, the parasellar region and the temporal fossa. They exceptionally develop at the level of the fourth ventricle We report the case of a 47-year old woman admitted for intracranial hypertension syndrome associated with walking disorders.

[Surgical treatment of spinal bone metastases].

Surgery for metastatic tumor is usually a palliative surgery, especially for spinal metastases, due to their anatomical localization. Surgical procedure should be accurately established to have simple outcomes and to start adjuvant treatment as soon as clinically possible. Therapeutic strategy should proceed after multidisciplinary consultation meeting (RCP).

[Rare medico-surgical emergency: spinal epidural abscess (about 3 cases)].

The awareness about infections in the epidural space is increasing thanks to the development of neurosurgery, including MRI. Spinal epidural abscess is a rare pathology but extremely serious from a functional point of view and potentially life threatening. We report three cases of male patients (the first one aged 52 years, the second 57 years and the third 63 years) with diagnosed spinal epidural abscess.

[A rare cause of spinal cord compression: spinal epidural arachnoid cyst (about 3 cases)].

Spinal epidural arachnoid cyst (SEAC) is a benign condition whose pathophysiology is still uncertain. It is most commonly asymptomatic but it can cause severe neurological sequelae especially when treatment is not received in time. We conducted a retrospective study of three patients treated for SEAC conducted in the Neurosurgery Department, Hassan II University Hospital, Fez.

[A rare cause of exophthalmia: intraorbital cavernous hemangioma (about a case)].

Cavernous hemangioma is the most frequent primary benign vascular tumor of the orbit in the adult; the median age of diagnosis is 42 years with a female predominance. This tumor develops slowly and has no tendency for spontaneous regression; it is electively located at the level of the retro-ocular muscular cone but it can develop in the extraconic space. Clinically it appears as progressive irreducible, non-pulsating, painless (unless there's an unexpected complication) exophthalmia, associated with decrease in visual acuity in 2/3 of cases.

Intradural extramedullary ependymoma: is there constantly a hormonal relationship?

Background: Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features.
