[Difficult catheterization]. / Un cathéter bien capricieux.

We report a case of a spontaneously ruptured implantable-chamber catheter which migrated to the right atrium. Removal by interventional radiology techniques is the treatment of choice for this type of complication.

[Effort-induced macroscopic hematuria revealing segmental and congenital absence of inferior vena cava]. / Hématurie macroscopique d'effort révélant une absence segmentaire et congénitale de la veine cave inférieure.

Absence of inferior vena cava (IVC) is an uncommon congenital abnormality with few clinical repercussions. We report the case of a 39 year old man with chronic pelvic pain, in whom a macroscopic hematuria episode occurring during exercise led to the discovery of an echographic pelvic venous stasis syndrome. Abdominal and pelvic computed tomography scanning then magnetic resonance imaging of inferior vena cava revealed absence of the postrenal segment of IVC with azygos continuation and considerable collateral venous derivations, leading to pelvic cavernoma.

[Pneumatosis cystoides intestinalis. Apropos of a case]. / La pneumatose kystique intestinale. A propos d'un cas.

Pneumatosis cystoides intestinalis is most frequently characterised by the presence of gaseous cysts, in the intra-parietal, subserous or sub-mucous zones of the colon. This complaint, with symptoms of non specific colic and the cause of chronic pain, generally progresses favourably but can be responsible for surgical complications. Characteristic signs are detected on an plain abdominal X-ray and by colonoscopy. The diagnosis can be established by CT or by ultrasonography but needs carefully trained operators. CT remains the most successful technique for the initial diagnosis and subsequent follow-up. Ultrasonography can also be used for follow-up. As the lesions regress rapidly, the diagnosis must established rapidly, otherwise the disorder might easily be incorrectly diagnosed.
