[Vertex aplasia cutis congenita with bone defect: Management synthesis and review of the literature].

Aplasia cutis congenita (ACC) of the vertex is a rare and potentially severe malformation. We report the case of a newborn boy presenting ACC of the vertex with a skull defect. Surgical closure of the skin was performed 5 days following birth, which allowed skin healing.

[Anatomic study and CT angiography with 3D reconstructions of the pulmonary arterial tree].

Aim Of The Study: To prove in vivo and on cadaveric lungs, the constancy of the collateral type of distribution for the right and left pulmonary arteries as described in classical books and modern studies; to estimate the frequency of the main branches observed and define an arterial tree of reference set up with the most common branches for reading the CT pulmonary angiographies.

Patients And Methods: Sixty three-dimensional reconstructions of pulmonary arterial trees (right: 30; left: 30) using the Volume Rendering Technique (VRT) performed from CT angiographic studies of 30 patients without bronchial, arterial or pulmonary pathology. Dissection of 16 pulmonary arteries from eight fresh cadavers injected with latex.

Split cervical spinal cord malformation and vertebral dysgenesis.

We report a case of vertebral malformation associated with diplomyelia believed to be a type II split cord malformation. Cervicothoracic level cases are exceptional. This article reports the case of an 11-year-old boy with no neurological symptoms who had not undergone surgery.

[Chondrosarcomas of skull base treatment].

Background And Purpose: Skull base chondrosarcomas are rare. Gross total removal is the treatment of choice, but can be difficult depending on the closeness of noble structures. Proton beam therapy can be associated in most cases.
