Cervical Pott's disease is a rare localization of spinal tuberculosis. The diagnosis of this affection is most often late which exposes to serious neurological complications. The diagnosis is often delayed by bundles of clinical and biological arguments and aided by the CT scan of the cervical spine. We report a new case of C3-C4 cervical tuberculo...

Primary dural lymphoma is a rare pathology, it is part of the malignant lymphoma of the central nervous system and it can reach the extradural or subdural space.

We report two cases of neurological complications, patients with known homozygous sickle cell disease, admitted to the Resusc...

We report a case of sacrococcygeal meningocele simulating a sacrococcygeal teratoma. Likewise, there are a discussion of the pathophysiology and surgical approach of these types of lesions. We present a case of an exceptionally large posterior coccygeal meningocele of a newborn, and show the interest of radio-echographic couple and the interest of...

Cranio-spinal dysraphisms are a set of congenital malformations resulting from a defect in closing the neural tube during embryonic development.
