[Clear cell sarcoma of the kidney in an adult: a case report]. / Sarcome à cellules claires du rein chez l'adulte: à propos d'un cas.

Clear cell sarcoma of the kidney rarely affects adults. It has an aggressive evolution, with a high rate of recurrence and mortality. We report the case of a 58 year old man with clear cell sarcoma of the kidney and discuss the benefit and value of medical imaging for management.

[Glomus tumor of the leg: a case report]. / A propos d'une tumeur glomique de la jambe.

Glomus tumor is an uncommon benign neuromyoarterial tumor. It most frequently involves the fingers, and only rarely involves other sites. The clinical, imaging and therapeutic considerations regarding a glomangioma of the leg in a 65-year-old-man are reviewed.

[Primary extensive hydatidosis of the thigh: unusual radiological aspects]. / Hydatidose primitive et étendue de la cuisse: aspect radiologique inhabituel.

Soft tissue involvement by hydatid disease remains unusual (5%) even in endemic areas. Patients typically present late because disease progression is slow and often asymptomatic. The authors report the unusual imaging appearance in a 59 year old woman with a one year history of progressive diffuse painless swelling of the left thigh. Ultrasonography showed multiple anechoic and hypoechoic cystic lesions, some of which containing serpentine echogenic structures consistent with partly calcified membranes. CT and MRI confirmed a diagnosis of hydatid disease and were helpful to demonstrate the relationship between cysts and adjacent structures. Surgical management was performed early because of fistulization to the skin.

[Sural false aneurysm disclosing the presence of Behçet's disease]. / Faux anévrisme sural révélateur d'une maladie de Behçet.

The authors report the case of a 35 year old patient that presented acutely with a false aneurysm of the tibioperoneal trunk diagnosed at Doppler US and CT angiography. Behçet's disease was considered because of a prior history of recurrent phlebitis, the presence of bipolar aphthae and a biological inflammatory syndrome. This case is of interest for two reasons: first, the atypical location of the false aneurysm, and second, the value of less invasive imaging techniques, namely Doppler US and CT angiography.

[Colonic tubular adenoma following ureterosigmoidostomy: CT features]. / Adénome colique tubuleux après urétérosigmoïdostomie: aspect tomodensitométrique. à propos d'un cas.

We report a case of benign colonic tubular adenoma arising in a 36-year-old female at the site of ureterosigmoidostomy performed 25 years before. The tumor was revealed by recurrent episodes of pyelonephritis; hydronephrosis was present. On colonic enema, the tumor appeared lobulated, 4 cm in diameter. CT scan showed a multiloculated mass, which enhanced after injection. Pathology revealed a tubular adenoma of the colon with cystic dilatation of glandular structures. The role of imaging studies in the follow-up of patients after ureterosigmoidostomy is discussed.

[False aneurysm of the abdominal aorta of hydatid origin]. / Faux anévrysme de l'aorte abdominale d'origine hydatique.

The rupture of hydatid cysts into the abdominal aorta is an exceptional and serious complication of the hydatid disease. We report a case of hydatid false-aneurysm of the abdominal aorta, explored by US Doppler, C.T. and arteriography.
