RESUMEN
Primary leiomyosarcoma of the thorax is a rare malignant mesenchymatous tumour. Most of those tumours occurring in the mediastinum arise from the oesophagus and great vessels, whereas an appearance in the soft tissue of the mediastinum is extremely rare. The rare incidence of this tumour and its slow growth reflect the difficulties in differential diagnosis according to their histopathology and location. The most common treatment is surgical resection. The authors describe a case of a leiomyosarcoma arising from soft tissue of the mediastinum and present a review of the literature.

Type 1 neurofibromatosis is the most common of all the phakomatosis. It is a hereditary neurocutaneous syndrome that may involve any organ or system of the body. Central nervous system lesions are frequent and dominated by neoplasms and nonneoplastic hamartomatous lesions. Craniocerebral vascular abnormalities are relatively rare, most often occlusive or stenotic. The occurring of intracranial aneurysms during the neurofibromatosis type 1 gives rise to the question of the fortuitous aspect or not of this association, especially as the quasi-totality of the reported aneurysms in the literature are sacciform and most often unique. We report an original case of ectasic diffuse vasculopathy of the cerebral arteries associated with neurofibromatosis type 1 in a 43-year-old man presented with seizures.

Paranasal sinus injuries by foreign bodies have a lower incidence compared with facial injuries. Among them, penetrating maxillofacial injuries to the sphenoid sinus and skull base remain rare. We report the case of a 41-year-old man who presented with, after a missile-related maxillofacial injury, a metallic foreign body enclosed within the sphenoid sinus with carotid-canal fracture. Angiographic evaluation showed a mass in the right internal carotid artery. The foreign object was successfully extracted through a transmaxillary sublabial approach with a good outcome. We discuss the extensive preoperative evaluation and interdisciplinary management of this unusual injury.

Pulmonary sequestration is a rare congenital malformation that receives its blood supply from a systemic artery. We report a case of pulmonary sequestration treated by ligature of the anomalous artery without pulmonary resection. Pulmonary sequestration must be treated surgically before the occurrence of severe complications.

The authors report the case of a 40 year old patient with history of cauda equina syndrome and pyramidal signs due to intramedullary rupture of a congenital dermoid cyst of the conus without associated spinal dysraphism. Diagnosis was suggested at magnetic resonance imaging (MRI) and confirmed by histological examination and percutaneous aspiration of the intramedullary cavity.

INTRODUCTION: Among the extra-pulmonary localizations, isolated tuberculosis of the sternum is rare and difficult to diagnose. OBSERVATIONS: A 30 year-old man presented with tumefaction of the sternum that had developed over the past two months and a 52 year-old woman had developed a painful tumefaction of the sternum over the past 4 months. In both cases, the histopathological examination of a biopsy confirmed the diagnosis of tuberculosis. Anti-bacterial therapy permitted the favourable progression of the disease. DISCUSSION: Such diagnosis is rare. Contamination can occur through contiguity, which was not manifest in either of the two cases. Confrontation between the histological and/or bacteriological samples is required.
