A rare presentation of mesenteric cyst as persistent ascites: A case report.

BACKGROUND: Mesenteric cysts have been typically described as cystic lesions of mesentery or omentum occurring either intra-abdominally or in the retroperitoneum. With no typical symptoms, the preoperative diagnosis of mesenteric cyst becomes challenging to establish. PATIENT AND METHODS: In this case report, we describe the case of a 29-year-old female who presented with abdominal distension for seven years associated with intermittent constipation. Following complete history, a meticulous physical examination was performed. Laboratory investigations and radiological imaging techniques were used to facilitate the diagnosis which was confirmed on laparotomy. RESULTS: Physical examination revealed abdominal ascites. Laboratory investigations were unremarkable. Abdominal ultrasound revealed multiloculated massive ascites. A well-defined cystic area 27 × 18cm displacing abdominal viscera was observed on computed tomography (abdomen and pelvis) with contrast medium. Exploratory laparotomy revealed a massive cyst involving almost the entire peritoneal cavity. On histopathology, no signs of malignancy were reported. The post-operative course was excellent, and the patient was discharged following surgery. CONCLUSION: As this lesion is rarely considered preoperatively, and the clinical manifestations can be non-specific, we report this case of mesenteric cyst mimicking ascites in order to inform improved decision making among healthcare professionals regarding the timely diagnosis and appropriate management.

Amyand's hernia associated with mesenteric chylous cyst in infant: a rare case report.

BACKGROUND: Amyand's hernia is a rare condition approximately 0.4-0.6% of all inguinal hernias. Although rare, the Amyand's hernia is worthy of discussion since the variable presentation that make clinical challenge to diagnose especially in infant. A mesenteric chylous cyst is rare disease and has not been reported in Amyand's hernia. CASE PRESENTATION: We report an unusual case of Type II Amyand's hernia with an enlarging chylous mesenteric cyst on the retrocaecal in the anulus into canalis inguinalis. A-2-months old infant presented with enlarging mass in the right scrotal. During laparotomy exploration, we found inguinal sac with intestinal and appendix content in the sac. In the edge site of the sac we found enlarging of mesenteric cyst on the retrocaecal in the anulus into canalis inguinalis. Based on the histopathology examination, the morphological feature is suitable for mesenteric chylous cyst appearance. CONCLUSION: Presentation of mesenteric chylous cyst is rare, and there was no report about it in Amyand's hernia. This unusual presentation should be considered by the surgeon, especially pediatric surgeon, in Amyand's hernia cases.

[Perforated mesenteric cyst causing abdominal pain in a 12-year-old girl].

In this case report, a 12-year-old girl was admitted to hospital due to abdominal pain. An intra-abdominal mass was seen on ultrasound and initially mistaken for an ovarian cyst. Later, a CT scan was performed, and it revealed an intraperitoneal cystic mass compatible with a mesenteric cyst, which is a rare benign abdominal abnormality. The cyst was removed by laparotomy, and histology confirmed the diagnosis. The patient had no readmissions afterwards.

Mesenteric cyst and recurrent abdominal pain in a patient with Gorlin-Goltz syndrome: a case report.

Gorlin-Goltz syndrome (GGS) is an infrequent autosomal do-minant multisystemic disease with complete penetrance and variable expressivity. It is estimated to have an incidence of 1:50,000 - 1:150,000 cases with a M/F = 1:1. This report describes a case of recurrent abdominal pain due to a large mesenteric cyst in a 38-year-old female patient affected by a rare disease: Gorlin-Goltz syndrome.

Mesenteric cysts and mesenteric venous thrombosis leading to intestinal necrosis in pregnancy managed with laparotomy: a case report and review of the literature.

BACKGROUND: Mesenteric cyst is a rare clinical entity especially in pregnancy; therefore, few cases have been reported in the literature. The standard method of their treatment is surgical excision either with laparotomy or laparoscopy. In addition, mesenteric vein thrombosis is a rare and life-threatening condition in pregnancy and needs immediate treatment because it can lead to intestinal necrotic ischemia. This is the first report of the coexistence of mesenteric cysts and mesenteric vein thrombosis during gestation. CASE PRESENTATION: A 27-year-old Greek woman, gravida 2 para 1, presented at 10 weeks' gestation to the Emergency Unit of our hospital complaining of diffuse abdominal pain which deteriorated the last 3 days, which was localized in her right iliac fossa, along with vomiting. She had undergone open laparotomy and right salpingo-oophorectomy at the age of 23 due to an ovarian cyst. Besides this, her personal and family medical history was unremarkable. She had never received oral contraceptives or any hormone therapy. On arrival, a clinical examination revealed tenderness on palpation of her right iliac fossa, without rebound tenderness or muscle guarding. Within 10 hours of hospitalization, her symptoms deteriorated further with rebound tenderness during the examination, tachycardia, and a drop of 12 units in her hematocrit value. An emergency laparotomy was performed. Two mesenteric cysts and a 60 cm necrotic part of her intestine were revealed intraoperatively. In the postoperative period, she complained of acute abdominal pain, tachycardia, and dyspnea. Computed tomography imaging revealed mesenteric vein thrombosis and pulmonary thromboembolism. She was treated with low molecular weight heparin and she was discharged on the 11th postoperative day. CONCLUSIONS: To the best of our knowledge, this is the first report in the literature of a simultaneous mesenteric cyst and mesenteric vein thrombosis in pregnancy. It is known that pregnancy is a state of hypercoagulation and clinicians should bear in mind this rare clinical condition in their diagnostic algorithm for acute abdominal pain.

Anemia as One of Presenting Symptoms in an Adult with Cyst and Torsion of the Omentum - A Case Report.

BACKGROUND: Torsion is an uncommon disorder of the omentum and cysts are one of the rarest causes of omental torsion. To our knowledge, this is the first report of a case of an omental cyst presenting with both omental torsion and anemia. CASE PRESENTATION: We herein present a case report of a 41 year old indian female patient who presented with anemia (hemoglobin concentration 6.5 g/dL) and intermittent abdominal pain caused by torsion of a hemorrhagic omental cyst. A computed tomography scan, showed an omental cyst with free fluid in the abdominal cavity. At abdominal exploration, 1.5 L of hemorrhagic fluid was confirmed in the abdominal cavity. The cyst and twisted omentum were removed en bloc. The patient had an uneventful postoperative course and was discharged on day 8. At her 2-month follow-up, she was no longer anemic (hemoglobin concentration 10.7 g/dL). CONCLUSION: Cases of anemia associated with omental torsion have been reported in children; however, to the best of our knowledge, this is the first reported case of such a presentation in an adult. In such patients, surgical removal is the treatment of choice. Persons with recurrent abdominal pain and anemia must be assessed carefully and their differential diagnosis should include omental torsion. Appropriate diagnosis and treatment help avoid complications.

[Infected jejunal mesenteric pseudocyst: A case report]. / Pseudoquiste mesentérico infectado en yeyuno: reporte de un caso.

BACKGROUND: Mesenteric cysts are very rare abdominal growths, generally asymptomatic, and which are usually detected incidentally while performing a physical examination or an imaging test. Complications such as infections, haemorrhage, torsion, rupture, or bowel obstruction, are seldom found in this pathology, but they can be a cause of acute abdomen. The purpose of this report is to describe the characteristics and the clinical outcome of a male patient with an infected mesenteric pseudocyst of the jejunum. CLINICAL CASE: A 49 year-old male was admitted to the emergency department with 6-day onset of abdominal pain, bowel obstruction signs, palpable tumour located in the upper hemi-abdomen, systemic inflammatory response syndrome, 36,100/mm(3) white cells, 4.21 ng/ml procalcitonin, abdominal computed tomography scan with evidence of a mesenteric cystic tumour. An exploratory laparotomy was performed, finding the presence of a mesenteric pseudocyst of the jejunum with infection signs, extirpated and sent for histopathological examination. The clinical progress of the patient was satisfactory with the discharge of the patient 7 days after the surgical intervention. CONCLUSION: These cysts can debut as an acute abdomen due to haemorrhage, infection, obstruction and/or bowel perforation, complications can be life threatening if not detected and surgically treated at an early stage by performing a resection of the pseudocysts, with or without bowel resection, depending on the location and the size of the cyst.

Quistes mesentéricos en la edad pediátrica: ¿qué son en realidad? / Mesenteric cysts in children

OBJETIVOS: Los quistes mesentéricos (QM) son tumores quísticos benignos, integrados en el tejido del mesenterio o del epiplón. Hemos revisado los casos de QM no enterógeno. MATERIAL Y MÉTODOS: Revisión de historias clínicas y biopsias de los casos intervenidos de QM en el periodo 2002-2012. RESULTADOS: Encontramos a 7 pacientes, edad media de 5,3 a˜nos (rango 3-11). El diagnóstico fue ecográfico en todos, salvo en uno. Todos presentaron dolor abdominal; 5 (71,4%) vómitos; 4 (57%) distensión abdominal; 3 (42,8%) fiebre; ninguno presentó obstrucción abdominal completa, aunque 2 pacientes (28,6%) presentaron suboclusión. El quiste fue pediculado o sésil en todos menos en uno, que englobaba raíz de mesocolon y retroperitoneo. La histología de todos ellos reveló malformación linfática. No hubo recurrencias. CONCLUSIONES: Los quistes mesentéricos en niños son en su mayoría malformaciones linfáticas del mesenterio, con clínica muy variada. En el 50-60% están integrados en el mesenterio y requieren resección del asa afectada y anastomosis

OBJECTIVES: Mesenteric cysts (MC) are benign cystic tumors that grow within mesentery or omentum tissue. We have reviewed the cases of MC reported and operated on in our centre. MATERIAL AND METHODS: Retrospective review of clinical records of MC cases during the period 2002-2012 RESULTS: A total of 7 patients were found. Mean age was 5.3 years (range 3-11). Abdominal ultrasound was the diagnostic tool in all cases, except for one, which was diagnosed during laparotomy. All presented abdominal pain, 5 (71.4%) vomiting, 4 (57%) gross abdominal distension, 3 (42.8%) fever, and none presented complete abdominal obstruction, although 2 patients (28.6%) had slight sub-occlusion symptoms. All MC were pedicled or sesil, except for our last case, which extended into the retroperitoneum. All specimens were reported as Limphatic Malformation. None recurred. CONCLUSIONS: MC in children are mostly Lymphatic Malformations of mesentery or omentum origin, and clinical presentation varies from chronic abdominal pain to sudden-onset peritonitis or volvulus. About 50-60% require intestinal resection and anastomosis
