[Granulocytic sarcoma of the maxillary sinus: a pediatric case report]

Granulocytic sarcoma is a rare malignant extramedullary neoplasm of myeloid precursor cells, occuring before or after onset of leukaemia. Involvment of the head and neck region is rare, generally concerning the orbit. To illustrate imaging findings of granulocytic sarcoma in an unusual location; maxillary sinus. We report a case of maxillary sinus granulocytic sarcoma in a 13-month old boy revealed by facial nerve palsy, ptosis and jugal swelling, without any evidence of haematological disorders. The patient underwent computed tomography and magnetic resonance imaging exam which demonstrated a non specific maxillary sinus mass with destruction of the orbit floor and the alveolar bone. Diagnosis was obtained after bone biopsy allowing histological and immunohistochemical studies. Granulocytic sarcoma is a serious condition because of the associated hematologic disorders. In a sinus or orbit location, imaging features are non specific. Unless hematologic history is present, diagnosis is difficult and an immuno histo chemical study is required

[Management of blunt duodenal and pancreatic injuries in children [about A series of 8 cases]]

The aim of this retrospective study is to report eight cases of blunt duodeno-pancreatic trauma in infants, emphasizing on the role of imaging in acute assessment of the lesions and in further management. We reported eight cases of duodeno-pancreatic injuries between 2006 and 2008, 5 boys and 3 girls with an age ranging from 3 to 12 years [median age:7 years]. Trauma circumstances were: car accident [n=2], domestic injury [n=5] and bicycle's fall injury [n=1]. All patients underwent abdominal ultrasonography and CT scan in the initial evaluation and during the follow-up. Imaging showed the following pancreatic lesions: 3 corporeal fractures, 2 caudal fractures and one between the corporeal and the caudal portions. Four pancreatic haematomas were found. Two isolated duodenal haematomas were found. Two patients improved spontaneously, the six others developed complications: 4 retroperitoneal collection. Management was chirurgical in one case medical in two cases, endoscopic in 2 cases and three percutaneaous drainages were performed. Blunt duodeno-pancreatic injuries in children have to be evaluated by an early imaging modality, in order to perform acute assessment of the lesions. Primary conservative treatment is advocated while clinic, biologic and imaging follow-up is required to detect complications, which management can be endoscopic percutaneous or surgical

[Pyelonephritis xanthogranulomatous in childhood: case report and litterature review]

Xanthogranulomatous pyelonephritis [XGP] is a specific form of chronic inflammatory kidney disease rarely seen in children. The Symptoms are often vague and non-specific the aim of this paper is to return the particularities of imaging features in xanthogranulomatous pyelonephritis. insisting on differential diagnosis with renal tumors, especially in case of no renal stone or tract obstruction evidence, We report a case of xanthogranulomatous pyelonephritis in a 2-year-old boy involving the lower renal pole which demonstrates the diagnostic difficulties encountered in this disease Xanthogranulomatous pyelonephritis is a rare condition in children and should be included in the differential diagnosis of a child presenting a renal mass

[CT findings in otosclerosis: a series of 11 cases]

Our study's aim is to evaluate the reliability of computed tomography in diagnosis, extension and post-surgical follow-up of otosclerosis. A group of 11 patients was examined during a period of 25 months from 2002 to 2004. All of them had clinically and audiometrically suspected otosclerosis with bilateral conductive hear loss in 7 cases [3 had surgical management], unilateral in 2, and mixed earing loss in 2. High resolution CT was performed once in 8 patients and twice in the 3 operated. CT showed otosclerosis foci in all our study's patients, which was bilateral in 9 and unilateral in 2. The extension of the Lesions varied from type 1A to type 4B according to the otosclerosis staging. Computed tomography is, so far, the most efficient imaging modality in otosclerosis, showing otosclerosis foci when the clinical features are doubtful, allowing an accurate extension of the lesions and detecting complications during post-surgical follow-up
