Mesenteric cysts.
Mesenteric cysts continue to be of special interest because of their diverse presentation and the lack of definitive diagnostic tests. Nine patients with mesenteric cysts were treated at St. Agnes Hospital between 1973 and 1984. The most common location was in small bowel mesentery (67%) followed by the mesocolon (33%). The mesenteric cysts were incidental findings in four of the nine patients (45%). Enucleation was the treatment of choice in eight patients (88%), followed by right hemicolectomy in one patient. Two patients had complications, one wound infection and one urinary tract infection. Simple enucleation has proven to be adequate treatment in most instances. Large bowel resection may be necessary when mesenteric cysts are located in the mesocolon and enucleation is not feasible without compromising the blood supply to the adjacent bowel.

Mesenteric cysts in children.
Mesenteric cysts are rare intraabdominal lesions of childhood that may vary in presentation from an asymptomatic mass to an acute abdomen. From 1970 to 1990, 15 children were diagnosed and treated for mesenteric cysts at Ste Justine Hospital in Montreal. The ages ranged from birth to 18 years (average age, 6 years). There were 9 boys and 6 girls. Ten patients required emergency surgery and five underwent elective surgery. The main presenting symptom was abdominal pain. Ten patients had preoperative ultrasounds that were diagnostic for a cystic mass in all patients. The second most frequent preoperative diagnosis was appendicitis. The cysts were located in the small bowel mesentery in 5 cases, the base of the mesentery with retroperitoneal extension in 4 cases, the transverse mesocolon in 4 cases, and the gastrocolic ligament in 2 cases. Operative procedures performed included complete cyst excision (9 patients), complete excision with intestinal resection (5 patients), and drainage of the cyst (1 patient). The only recurrence in this series occurred after drainage. One other patient had recurrence of a mesenteric cyst following resection performed elsewhere. Mesenteric cysts are rare in children, are usually symptomatic, and are most commonly misdiagnosed as acute appendicitis. Accurate preoperative diagnosis is possible with current ultrasonographic imaging techniques. Complete cyst resection is the procedure of choice and results in an excellent outcome.

Mesenteric cysts in Nigerians.
Mesenteric cysts are uncommon and are said to be rarer among blacks than in caucasians. We report six mesenteric cysts seen in five patients over a 9 1/2 year period with an incidence of one in 48,497 hospital admissions. there were three males and two females. Ultrasonography was carried out in three of our five cases. There is need to include mesenteric cyst in the differential diagnosis of an abdominal mass. Surgery was the mainstay of treatment. At laparotomy, five of the cysts were found in the mesentery of the small bowel. Simple enucleation was done in one patient while cyst resection with adjacent bowel was carried out in three patients. There were two cysts in the youngest patient and these were internally drained. All the patients did well with uneventful post-operative period with no mortality. Follow up had been from 14 months to 6 years.

Mesenteric cysts in pregnancy. A case report.
Mesenteric cysts are rare. These large, often asymptomatic growths may be misinterpreted easily by the clinician as representing either benign or malignant ovarian tumors, renal masses, or hepatic tumors or cysts. We treated a women for a mesenteric cyst complicating her second pregnancy. Because of the increasing use of ultrasound in a wide variety of pregnancy complications, and because of the mesenteric cysts's unique sonographic appearance (resembling that of a benign ovarian tumor), such a cyst must be included in the differential diagnosis of large, cystic abdominal masses in pregnancy.

[Sonographic appearances of mesenteric cysts--report of 2 cases].
Mesenteric cyst is defined as a cystic mass located in the mesentery, and has rarely been reported. Before the clinical use of ultrasound (US), the imaging diagnosis of the abdominal mass depended on plain X-ray films and contrast examinations to delineate the space occupying lesion. The later use of US enables us to readily identify mass character. For example, whether it is cystic or solid, with or without septum, or whether there is sediment in the cyst. US examination is the method of choice in evaluating abdominal masses. Two cases of pediatric mesenteric cysts were brought to our hospital on account of complication. US of the first patient revealed a huge cystic mass with sediment and septae in central abdomen. Mild hydronephrotic change of the right kidney was found. The pathology showed nonepithelial lining multiloculated cyst surrounded by a thick, fibrotic granulomatous wall with suppurative cell infiltration and some calcifications. The histopathological diagnosis was an infected pseudocyst. The other patient had a cyst which twisted the jejunum and resulted in intestinal obstruction. US found dilated intestinal loops and a septate cystic mass in epigastrium. The pathology showed a multiloculated cyst with mesothelial lining, representing a mesothelial cyst. Both patients were treated surgically and had an uneventful recovery. In this article we described and explained the findings on US, discussed the differential diagnoses and compared different imaging modalities.

Mesenteric cysts and intra-abdominal cystic lymphangiomas.
Although mesenteric cysts and intra-abdominal cystic lymphangiomas are uncommon and clinically confusing lesions, histologic and ultrastructural evidence suggests that they are pathologically distinct. Differentiation of these lesions is important since lymphangiomas may follow a proliferative and invasive course. Of 28 cases documented at laparotomy, histologically eight patients (29%) had cystic lymphangiomas and 20 patients (71%) had mesenteric cysts. Lymphangioma was found to be exclusively a disease of childhood and young adulthood (mean age, 10 years); mesenteric cyst was found in all age groups (mean age, 44 years), and two thirds of these patients were over 40 years old. Patients with lymphangiomas more frequently were male (75% vs 30%), symptomatic (88% vs 35%), and had ascites (50% vs 0%) and larger lesions (mean, 8.8 vs 4.7 cm) when compared with patients with mesenteric cysts. Complete excision was possible in all but four patients, with no operative deaths and a postoperative complication rate of 7%. After a mean follow-up period of four years, there were no recurrences among 16 patients who had undergone complete excision.

[Mesenteric cysts in Denmark in 1980-86].
On the basis of a material of mesenteric cysts from a period of six years in all Denmark, the symptomatology, diagnosis and treatment of mesenteric cysts (MC) are described. These cysts are rare: approximately one par 130,000 somatic admissions. Mesenteric cysts may be encountered along the entire gastro-intestinal canal from the duodenum to the rectum but are, however, most frequent in the mesentery of the small intestine. The symptoms were variable and depended upon the site, mobility, tension on the mesentery, the complications and, to a lesser extent, on the size. Ultrasonic scanning was the most important diagnostic aid. 5% of the cysts contained chyle and up to one third of these are stated to be malignant. Computed tomographic scanning is recommended preoperative as the density can reveal whether the content is chylous. Enucleation of mesenteric cysts would be attempted but, in cases of large cysts which prove difficult to resect, internal marsupialization may be employed. Material with low frequencies of recurrence and few complications have been presented employing this therapeutic method.

Omental and mesenteric cysts in Nigerian children.
Omental and mesenteric cysts are rare intra-abdominal lesions which may be congenital, traumatic, neoplastic or infectious in origin. They give rise to non-specific clinical features and may be a cause of the surgical acute abdomen, especially in children. Correct preoperative diagnosis is infrequent but a high index of suspicion and use of ultrasonography when available would improve clinical diagnosis. Six omental and mesenteric cysts encountered in five children over a 10-year period (1978-87) are reported. All the cysts were congenital. Three patients presented with non-specific symptoms and two presented with acute abdomen. Correct preoperative diagnosis was made in two patients. All five patients had surgery. Two had enucleation of the cysts, two had excision of the cysts with adjacent bowel segment and one patient with two cysts had partial excision of the wall of the cysts with free internal drainage into the peritoneal cavity. All patients survived.

Urogenital mesenteric cyst with fallopian tubal features.
Urogenital cysts are retroperitoneal or mesenteric cysts that are derived from vestigial remnants of the embryonic urogenital apparatus. Although their precise embryonic origins are usually obscure, occasionally they display histologic features indicative of a mesonephric or metanephric origin. This report describes an unusual mesenteric müllerian cyst consisting of an endosalpingial lining and two-layered smooth muscle walls, probably representing a müllerian duct duplication cyst.

A case of mesenteric cyst diagnosed by ultrasound examination and a review of Japanese literatures.
Mesenteric cyst is relatively rare, and its diagnosis is difficult. We carried out an ultrasound examination on a 6-year-old boy who showed intestinal obstruction. This examination revealed an abdominal mass, and he was diagnosed as mesenteric cyst. Later it was confirmed by operation. The histopathological examination revealed that it was a lymphangioma. A review was also carried out on 288 cases of mesenteric cyst in Japan.

Calcified mesenteric cyst.
Reported is a case of a calcified mesenteric cyst that was causing obstruction of the small bowel. Because only roughly one case occurs per 100,000 hospital admissions, mesenteric cysts are rarely thought of and may be difficult to diagnose. The differential diagnosis includes such critical lesions as aortic aneurysm, pancreatitis, ovarian cysts, omental cysts, and lipomas of the mesentery. The proper treatment of these rare lesions is somewhat influenced by causative factors: embryonic, traumatic, neoplastic, infectious, or degenerative. Surgical excision or enucleation is preferred to internal or external drainage. Ultrasonography is becoming increasingly valuable as a diagnostic tool.

Bowel obstruction secondary to mesenteric cyst formation.
A rare cause of intra-abdominal obstruction, mesenteric cysts derive from lymphatic tissue. The differential diagnosis should include mesenteric cyst when the patient presents with a history of multiple episodes of partial small-bowel obstruction or with an asymptomatic abdominal mass. A year-old girl was brought to the Family Practice Center with episodic, sharp, nonradiating, left-sided, mid-upper-abdominal pain. Examination indicated a possible diagnosis of mesenteric adenitis. Due to variation in the signs and symptoms of the condition, it appears that the use of ultrasonography is the most effective, nonoperative method of evaluation. Ultrasonography appears to be the most effective, nonoperative method of evaluation. Surgery is the only definitive diagnostic and therapeutic modality.

Recurrent retroperitoneal mesenteric cyst. A case report and review.
A mesenteric cyst is an uncommon cause of a palpable abdominal mass. A correct preoperative diagnosis can be made by the combined use of radiographic and sonographic examinations in conjunction with the clinical features. A patient with a retroperitoneal cyst extending into the leaves of the mesentery is presented. The cyst recurred 4 years after surgery.
Child↗
[Mesenteric cysts in childhood].
5 children with mesenteric cysts, 3 boys and 2 girls, aged 2 to 10 years, were admitted with acute abdominal pain. In adults the most common symptom is chronic abdominal pain whereas in children the onset of symptoms is acute due to intestinal obstruction. Sonography, performed in two patients, is the diagnostic method of choice. Excision of the cyst required resection of the small intestine in 2 patients, while simple enucleation was possible in 3. All 5 patients survived, and there have been neither complications nor recurrences. Early recognition and appropriate resection of these occasionally life-threatening malformations are associated with a good prognosis.
