As the fluid continues superiorly into the inferior extension of the splenorenal recess and perhaps to some degree medially within the unusual variant of a retropancreatic recess.
Paracolic gutter ct anatomy.
The left medial paracolic gutter.
The paracolic spaces gutters are located lateral to the peritoneal reflections of the left and right sides of the colon fig 8a.
There are watershed regions in the peritoneal cavity that are areas of fluid stasis.
Root of the sigmoid mesentery.
The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.
Between the outer wall of the colon and back side of the abdominal wall there is an open space known as the paracolic gutter.
The left lateral paracolic gutter.
These gutters are used to drain infectious material away from the essential internal organs.
The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.
There are two paracolic gutters.
Rarely the appearance of thickened fascia may be simulated on ct supine scans by intraperitoneal fluid within posterior peritoneal recesses particularly on the left 17 52 53 fluid layering in a deep left paracolic gutter may mimic thickening of the lateroconal fascia and a portion of the posterior renal fascia.
The right lateral paracolic gutter.
The main paracolic gutter lies lateral to the colon on each side.
Etiologically it means a channel adjacent to the abdominal wall.
On the right hand side the right lateral paracolic gutter is found lateral to the ascending colon and medial to the lateral part of the anterior abdominal wall.
It is larger than the left paracolic gutter which is partially separated from the left subphrenic spaces by the phrenicocolic ligament.
A less obvious medial paracolic gutter may be formed especially on the right side if the colon possesses a short mesentery for part of its length.
It predominantly flows up the right paracolic gutter which is deeper and wider than the left and is partially cleared by the subphrenic lymphatics.
Both paracolic spaces are in continuity with the pelvic peritoneal spaces.
The right paracolic gutter is larger than the left and communicates freely with the right subphrenic space.
The paracolic gutters paracolic sulci paracolic recesses are spaces between the colon and the abdominal wall.
It is also known as sulci paracolic and paracolic recesses.
The phrenicocolic ligament separates the left paracolic gutter from the left supramesocolic space it is continuous with the peritoneum of the left lateral aspect of the transverse mesocolon and the splenorenal ligament adjacent the splenic hilum 1 it attaches to the parietal peritoneum along the posterolateral aspect of the diaphragm at the level of the eleventh rib.
Paracolic gutters are open areas between the wall of the abdomen and the colon.
The right paracolic gutter is a component of the right inframesocolic space continuous superiorly with the right subhepatic and right subphrenic spaces.
