case_images: A) Intraoperative findings of MCL showing thin-walled chylous fluid-filled, significantly attached to the jejunum. B) Tissue samples were stained using hematoxylin and eosin. Histopathological view at 40x (left) and 100x (right) magnification showed the dilated cystic spaces, coated with endothelial, which contained amorphous eosinophilic fluid, supporting the diagnosis of lymphangioma.

case_images: A yellowish-white tumor mass containing chylous fluid was found in the jejunal mesentery measuring 15 x 8 x 5 cm3 that pressed against the jejunum (Type 2 MCL) (Fig. 1A). Next, we excised the tumor mass except the one significantly attached to the jejunum, and sent the tissue samples for histopathological examination (Fig. 1B).

case_images: A) Abdominal X-ray showed small bowel distention. B) Barium follow-through showing volvulus with very high semi-organoaxial obstruction at the jejunum. C) Intraoperative findings showed thin-walled MCL containing serous fluid. D) Tissue samples were stained using Hematoxylin-eosin. Histopathological view at 40x (left) and 100x (right) magnification showed tissue cyst wall in the form of connective tissue and smooth muscle infiltration by lymphocytes and blood vessels dilated portion and extravasation of erythrocytes supporting a diagnosis of cystic lymphangioma with inflammation.

case_images: Abdominal X-ray was performed and showed small bowel obstruction (Fig. 2A), whereas the barium follow-through findings showed volvulus with very high semi-organoaxial obstruction at the jejunum (Fig. 2B). The patient underwent exploratory laparotomy and two mesenteric cysts were found with a diameter of each around 10 cm and 8 cm (Fig. 2C). Marsupialization and partial excision were performed; tissue samples were sent for histopathological examination and the results supported the diagnosis of cystic lymphangioma (Type 1 MCL) (Fig. 2D).

case_images: A) Abdominal CT scan showed oval tubular cystic mass in the middle of the abdomen which extends into the pelvic cavity and displaces the bowel to the anterior; tumor origin difficult to evaluate. B) Intraoperative findings showed thin-walled cystic lymphangioma contains serous fluid. C) Tissue samples were stained using hematoxylin and eosin. Histopathological view at 40x (left) and 100x (right) magnification showed the dilated cystic spaces, coated with endothelial, contained amorphous eosinophilic fluid, supporting the diagnosis of lymphangioma.

case_images: Computerized tomography scans were performed and showed an oval tubular mass in the middle of the abdomen (Fig. 3A). The patient underwent explorative laparotomy, and we a found tubular-shaped MCL sized around 10 x 5 cm that had entered the retroperitoneal and pelvic cavity (Fig. 3B). Marsupialization and partial excision of the mass were performed; tissue samples were sent for histopathological examination (Fig. 3C).

case_images: A) Contrast magnetic resonance imaging revealed suspicious multilocular large mesenteric cysts. B) Intraoperative findings showed multiple mesenteric cysts attached to the transverse colon and descending colon.

case_images: Abdominal X-ray was performed showing enlarged liver and enlarged kidney, whereas the contrast Magnetic Resonance Imagery showed suspiciously large mesenteric cysts, which were multilocular (Fig. 4A). The patient underwent exploratory laparotomy and multiple mesenteric cysts were found, multilocular with the largest sized around 20 x 15 x 10 cm3 that had entered the retroperitoneal area and attached in part to the transverse colon and descending colon (Type 4 MCL) (Fig. 4B).
