[Cholestatic icterus due to primary duodenal lymphoma]

Primary lymphoma of the duodenum presenting with obstructive jaundice is a rare entity. We report a case of primary non-Hodgkin lymphoma of the duodenum producing biliary obstruction, definitively diagnosed by ultrasound-guided fine needle biopsy. Complete remission of the disease occurred after chemotherapy.

[Pericardial hydatid disease: three case reports]

Hydatid disease of the heart is very rare, representing about 0.2 to 2% of all cases. Most hydatid cysts of the heart are located within the left ventricular wall. Pericardial location is also very rare and patients present with various symptoms. US and CT have a primary role in the diagnostic workup of this disease.

[Paraganglioma and pregnancy]

A paraganglioma is an extra-adrenal pheochromocytoma, rarely observed during pregnancy. Maternal prognosis depends on early diagnosis and multidisciplinary management prior to tumor resection. The tumor is localized by ultrasonography or MRI. During the post-partum, and if MRI is not available, CT is often sufficient. We report a paragangliona in a patient with intrauterine fetal demise at 27 weeks gestation diagnosed by ultrasonography and computed tomography, who underwent surgical resection.

[Tuberculosis of the breast: a case report]

Tuberculosis of the breast is rare. It occurs in young women. Because the clinical and imaging findings are non specific, the diagnosis of a breast cancer is often suggested. This requires to obtain cytology and/or histology for a definitive diagnosis. On the basis of a case report of tuberculosis of the breast in a 14 years old girl, imaged by ultrasonography and computed tomography, we attempted to demonstrate the contribution of imaging and associated diagnostic pitfalls.

[Acute non-traumatic mediastinitis]

Acute mediastinitis is uncommon. When it occurs, it usually follows an esophageal perforation or thoracic surgery.

CASE REPORT

We report on a case of a ten-year-old girl with non traumatic mediastinitis secondary to a pleuro-pulmonary infection due to Klebsiella pneumoniae.

[Post-traumatic hepatic artery pseudoaneurysm. A case report]

CASE REPORT

We report a case of traumatic hepatic artery pseudoaneurysm in a 9-year-old child. The diagnosis was made by duplex sonography and helical CT angiography. Arteriography confirmed and managed the lesion with transcatheter embolization.

CONCLUSION

The traumatic hepatic artery pseudoaneurysm is an uncommon complication of liver trauma in children whose diagnosis is made by duplex sonography and CT angiography. Endovascular embolotherapy is the treatment of choice.

[Subcapsular hematoma of liver during pregnancy: report of 4 cases]

A Subcapsular hematoma of the liver is a rare but very serious complication of pregnancy. Diagnosis is confirmed at imaging (Ultrasound, CT, MRI) since clinical symptoms are not specific and biological signs have a delayed manifestation. The management of this complication depends on the integrity or rupture of Glisson's capsule. We report the cases of 4 patients and review of the literature.

[Spinal intradural hydatid cyst. A case report]

The authors report the case of a 13-year-old girl in whom the diagnosis of intradural hydatid cyst was suspected on CT scan and MRI and confirmed at surgery. The interest of this case is related to the extremely rare location and its severe prognostic. CT scan and MRI can easily make an anatomic and topographic diagnosis of the intradural hydatid cyst.

[Congenital urethrocele in children. A case report]

Congenital urethrocele is a fairly rare disease in children. The authors report the case of a 9-year-old child presenting with a penoscrotal mass. Pressure on the mass produced urine. The diagnosis of urethrocele was established by ultrasonography and cystourethrography. Urethroplasty was successfully performed.

[Polyps of the posterior urethra in children. Apropos of a case]

Posterior urethral polyp is a rare disease, predominantly affecting boys. The authors report the case of an 10-month-old boy admitted to hospital with acute urine retention. The diagnosis of polyp was established on cystourethrography, ultrasonography and endoscopy. The polyp was resected via a bladder incision after failure of transurethral resection. Posterior urethral polyp is a benign tumour whose clinical presentation is dominated by signs of lower urinary tract obstruction. Cystourethrography and ultrasonography confirm the diagnosis and assess the repercussions on kidneys and bladder. Endoscopy has a double role: diagnostic and therapeutic.
