The most common atypical locations are the gastrointestinal tract, urinary tract, lung, as well as abdominal surgical scars. Its diagnosis is still very difficult, especially when it manifests itself as an acute large bowel obstruction. We report the rare case of a 41-year-old patient diagnosed with acute colonic obstruction following a rectal tumor. She had undergone colonostomy even though colonoscopy biopsies were nonspecific, and a computed tomography (CT) scan was requested. It showed an adnexal heterogenous mass, therefore the patient had a laparotomy and a subtotal hysterectomy with bilateral salpingo-oophorectomy and a biopsy of the recto-colonic hinge. Histologic examination revealed a diagnosis of rectal endometriosis. The purpose of this work is to report a rare case of colonic endometriosis responsible for an acute large bowel obstruction.展开更多

The petrous bone computed tomography (CT) is a valuable tool for diagnosing ear pathologies and evaluating surgical possibilities. In children, the ear has the peculiarity of having the morphology and size of adults, and the only difference resides in the components of the middle and inner ear related to the growth of the temporal bone and the state of ossification which are progressive with age. Some aspects of growth can simulate pathology and must be known. The pneumatisation of the temporal bone occurs gradually after birth and in several outbreaks until adulthood. The external auditory canal, the internal auditory meatus and the petromastoid canal progressively reach the adult aspect because of the growth of the petrous bone. This work aims to highlight the particularities of the petrous bone CT in pediatrics, since it has become widely used in the exploration of malformations, trauma, infectious complications of the ear and in the assessment of deafness.展开更多

Case report: A 7-year-old patient was admitted for purulent pleurisy, whose cytological study of the pleural fluid isolated lymphoblastic cells in favor of a T-type lymphoblastic lymphoma, a very rare mode of revelation in current practice. Conclusion: Pediatric lymphoma takes on different aspects, and it is important to look for it systematically in order to ensure adequate management.展开更多
