Cerebral tumours in children occur in approximately 2.5 cases per 100 000 inhabitants every year in developed countries, however, they remain misunderstood in subSaharan Africa, where there is a problem with diagnosis and treatment. The objective of this retrospective work was to illustrate the clinical, scanographic and histological aspects of cerebral tumours in children in Yaoundé. Children who have had their cerebral tumours operated on were included, the age of whom varied between 0 and over 15 years. In all cases, the working diagnosis was made using scanography and the confirmed diagnosis was determined using histology. Cerebral tumours in children (42 cases) represented 35.29% of all cerebral tumours (119 cases). Intracranial hypertension represented the most frequent method of discovery (88.09%) followed by cerebellar syndrome (37.5%). The subtentorial position was the most frequent and represented 54.76% of cases. Cerebral tumours in children are frequent in Yaoundé. The subtentorial position was most frequently encountered. Astrocytoma was the most frequent type in the histology. The diagnosis essentially rests on computed tomography which enables the histological diagnosis to be targeted in 71.43% of cases and the tumour to be located. Source

Lipoblastomas are rare benign mesenchymal tumors of fetal white fat tissue appearing most commonly in children under 3 years of age, and usually affecting the extremities. Only nine cases of intrascrotal lipoblastoma have been reported to our knowledge, and although they are benign, in one case an orchidectomy was performed. We describe two new cases of intrascrotal lipoblastoma, and review the literature. Source

Primary endobronchial tumors are rare in children and they include a broad spectrum of lesions. The aim of this study was to determine the characteristic features, treatments and outcomes of these tumors. We report a retrospective analysis of all patients treated for endobronchial tumor in nine French hospitals between 1990 and 2010 and a comparison of the results with those reported in the medical literature. Twelve tumors were reported: five low grade muco epidermoid carcinomas, two inflammatory myofibroblastic tumors, two hemangiomas, one anaplastic large cell lymphoma, one carcinoid tumor, and one juvenile xanthogranuloma. The mean age of the patients was 7.5 ± 3.5 years. The most common sign revealing the disease was persistent atelectasis or recurrent pneumonia (eight cases). The other revealing signs were a persistent bronchospasm (three cases) and hemoptysis (one case). The clinical presentation, biology, serum tumor markers, and chest X-ray abnormalities were not specific to a particular histological diagnosis. Chest CT scan revealed the presence of an endobronchial tumor in 11 cases. Nine tumors could be diagnosed from a biopsy obtained by video endoscopy. Complete surgical resection was performed in seven patients. Bronchoscopic removal was performed in five cases and was successful in three. There were no deaths. Endobronchial tumors are rare in childhood and their histology is diverse. Chest CT scan and per-endoscopic endobronchial biopsies are required for diagnosis, when possible. Surgical or endoscopic treatment should be discussed by a multidisciplinary team. Despite the multiple etiologies, the prognosis of these tumors is good if diagnosis is early and if resection is complete. Long-term recurrences have been described, so long-term follow-up of these children is recommended. © 2014 Wiley Periodicals, Inc. Source

The practices related to patient radiation protection are poorly documented in sub-Saharan Africa because of the lack and/or weak enforcement of the related legislative and regulatory frameworks. This study investigates the justification and optimization of pediatric CT scans in two university teaching hospitals in Yaoundé in Cameroon. 171 CT scans in pediatric patients below 15 years of age performed during one trimester were surveyed. The data collection form was adapted from a dosimetric assessment sheet from the French Institut de radioprotection et de sureté nucléaire. The guidelines were those of the Société française de radiologie and the Société francophone d'imagerie pédiatrique et prénatale. Each CT scan was assessed and the CT dose index and dose length product were compared with the Diagnostic Reference Levels (DRLs) of the above-mentioned guidelines. While all the CT exams were justified, protocols were not readily available and varied amongst teams and units. The tension conformed in 87.7% of cases and 15.2% of DLPs were higher than the DRL for thoracic and abdominal CT scans performed under helical mode and brain CT scans performed sequentially. Readily available optimal CT protocols for children are urgent to improve upon the pediatric CT practices in these two units with a high turn-over rate of technologists and radiology residents. © 2012 EDP Sciences.

Our experience of the deep inferior epigastric artery perforator flap has led us to perform systematically an abdominal CT-scan for the pretherapeutic checking. This exam gives us a precise vascular mapping of musculocutaneous and septocutaneous perforators artery of the flap, may enable a better orientation in the dissection and reduce the surgery time. We have enlarged the indication of this exam to the members flaps who needs the dissection of a musculocutaneous or a septocutaneous perforators vessels: Nakajima's et al. classification [1]. The mapping of perforating vessels on 3D reconstruction pictures helps us to planify the vascular cutaneous autologous grafts. © 2009 Elsevier Masson SAS. Source
