Congenital cardiac diverticulum is a rare malformation formed by an outpouching of the ventricular wall, in particular the left ventricle. The thoraco-abdominal type is more frequent than the isolated thoracic type. Topographical and imaging considerations regarding an isolated congenital left ventricular diverticulum incidentally discovered in a 9-year-old-boy are reviewed.
Primary non Hodgkin's lymphoma of the liver is a very rare entity, compared with secondary hepatic lymphomatous involvement. It is exceptional in children. The authors report the case of a 9 year-old boy, who presents a primary hepatic lymphoma and review the role of medical imaging for diagnosis and follow-up.
The authors report a case of tubular duplication of the oesophagus discovered in a 1 month old infant and describe the main characteristics of this rare anomaly.
The incidence of abdominal tuberculosis has increased over the last decade and can mimic any other disease. Pancreatic involvement is an uncommon cause of jaundice in children. A case of obstructive jaundice due to pancreatic tuberculosis in an infant, with hepatic involvement is reported. The sonographic and computed-tomographic features are described.
We report a case of Lemierre syndrome with extensive thrombophlebitis of the internal jugular and subclavian veins with multiple septic emboli to the lungs and pericardium. This report illustrates a case of this forgotten disease in a child and the unusual presence of pericardial involvement.
Behçet's disease is a systemic condition whose discovery during hemoptysis on a pulmonary artery aneurysm is rare, especially in children. Through the case of a 11-year-old boy, the authors emphasize the importance of imaging in diagnosis of this disease, whose progression can be fatal if hemoptysis is violent.
Telangiectatic osteosarcoma is a rare entity and rarely involves flat bones. The authors report the case of a 4 year old child, with a four month history of progressive left shoulder swelling. Radiographs and CT of the left shoulder revealed a large lytic lesion with cystic areas of the scapula, simulating the appearance of an aneurysmal bone cyst. Surgical biopsy was performed and showed telangiectatic osteosarcoma.

Isolated involvement of the sternum is rare, representing less than 1% of tuberculosis osteomyelitis. Only a few cases of sternal tuberculosis have been reported in the pediatric literature. The authors report the case of a 10 year old boy presenting with a 6 month history of presternal swelling and pain. Computed tomography (CT) showed a ring-enhancing hypodense soft tissue mass surrounding the sternum, with marked cortical thickening. Treatment included both surgical intervention and medical therapy.
Lipoblastoma is an uncommon benign soft tissue tumor of infancy and early childhood with a predilection for the extremities. CT and MRI can confirm the presence of fat components in the tumor. In addition, MRI better shows the anatomical extent. By showing lipoblastoma proliferation, histology confirms the diagnosis. Gross total excision is the treatment of choice. The authors report a case of unusual lipoblastoma of the axillary region, composed of fatty components with multiple cystic areas presenting at birth, with recurrence 9 months after excision.
Isolated tuberculous involvement of the liver and spleen is infrequent. We report such a case in a child. The differential diagnosis of isolated multi-nodular diseases of the liver and spleen is reviewed.
Persistent mullerian duct syndrome with transverse testicular ectopia is a very rare pathological association, often fortuitously discovered in boys during repair for inguinal hernia or cryptorchidism. The authors present the case of an 15 year old adolescent with cryptorchidism, in whom ultrasonography of the right iliac fossa showed 2 testicles and a uterus. Surgical exploration confirmed the diagnosis.
The cerebro-costo-mandibular syndrome is a rare and serious congenital disorder characterized by the association of posterior rib malformations, micrognatia and mental deficiency. Death due to respiratory failure is usual during the first days or months of life. The various clinical and radiological aspects of this disease are described based on a recent observation.
OBJECTIVE: To report the ultrasonographic aspects of ovarian torsion in nine pediatric cases. PATIENTS AND METHODS: The age range was from 16 months to 14 years. The patients presented with a variety of symptoms, including pain in the site of torsion. Ultrasonography was performed in all patients, and color Doppler studies in four. RESULTS: Ultrasonography showed a cystic mass in six patients, a solid mass with peripheral cysts in two patients and an adnexal cyst in one patient. Color Doppler revealed absence of flow in three patients. The patients were treated by coeliosurgery. CONCLUSION: Ovarian torsion is a serious gynecologic emergency. Torsion is rare during childhood and has a non-specific clinical presentation. Ultrasound and Doppler are the imaging study of choice. The ovarian salvage was attributable to the combination of delay in patient presentation and surgical delay.
The authors report a case of non-Hodgkin lymphoma with involvement of the calcaneus and ovary in a 4 year- old girl. Calcaneal involvement by this tumor is unusual and ovarian involvement is infrequent.
Bronchogenic cysts are extremely rare in the tongue. We explain this localization by abnormal detachment of accessory lung buds from the primitive foregut. MR is the best imaging modality to evaluate lesions of tongue. Enucleation is the best treatment option. We present and discuss the case of a six month old infant presenting with a congenital tongue mass. This mass was a bronchogenic cyst.
Metatropic dwarfism is a rare heritable skeletal dysplasia. We report on two brothers, 4-month-old and 9-year-old, affected by the disease. Clinical and radiological features of the disease at different ages are discussed. Prenatal diagnosis is possible by ultrasonography. No treatment is available. Prevention by genetic counselling remains the principal possible assistance to high risk families.
