[Splenic rupture following colonoscopy: report of an unusual case in the absence of underlying splenic disease]. / Rupture splénique après coloscopie: à propos d'un cas inhabituel survenant sur une rate initialement saine.

Splenic injury following colonoscopy is rare and, to our knowledge, 18 cases only have been reported so far in the literature. The presumed mechanisms for splenic injury during colonoscopy are direct trauma to the spleen or excessive traction of the splenocolic ligament this latter mechanism being due to decreased mobility between the spleen and the colon secondary to adhesions. Splenomegaly or underlying splenic disease are two conditions which are considered to be predisposing factors to splenic injury. We report one case of splenic rupture which was due to colonoscopy in the absence of any underlying splenic disease. This case was diagnosed and monitored by computed tomography, thus avoiding unnecessary splenectomy.

[Carcinoid tumor of the small bowel: value of hydro-MR imaging for diagnosis]. / Tumeur carcinoïde de l'intestin grêle: apport d'une technique d'hydro-IRM dans le diagnostic.

Hydro-MR imaging is a technique based on the use of a strongly T2-weighted single-shot fast spin-echo (SSFSE) sequence, similar to that used for MR-cholangiography. We report herein one case of carcinoid tumor of the small bowel diagnosed by hydro-MR imaging. This non invasive MR technique showed suggestive features such as radial convergence and segmental dilatation of a small bowel loop, similar to those seen on conventional follow-through studies. This case illustrates the major role that may be played in the future by hydro-MR imaging for the non invasive diagnosis of carcinoid tumor of the small bowel without the use of ionizing radiation.
