068. Revealing the Hidden Giant: When Giant Appendicitis Mimics A Mesenteric Cyst in Recurrent Sigmoid Volvulus – A Case Report

Background: Giant appendicitis is an exceptionally rare condition that can mimic other intra-abdominal pathologies, including mesenteric cysts, due to its unusual size and presentation. Distinguishing between these entities is chalenging due to its resemblances. Case: A 56-year-old woman with a history of chronic constipation who was admitted to the emergency department with abdominal distension and inability to defecate. Abdominal examination revealed a distended abdomen with visible bowel contour and an abdominal X-ray showed coffee bean appearance, suggestive of sigmoid volvulus. An exploratory laparotomy revealed twisting of the sigmoid colon. After reducing the volvulus and confirming viability of the sigmoid, a loop sigmoidostomy was performed to prevent recurrent volvulus. Intraoperatively, a mass resembling a mesenteric cyst was identified, which was subsequently confirmed to be a case of giant appendicitis. Conclusion: Considering giant appendicitis in the differential diagnosis of abdominal masses resembling mesenteric cysts is important, particularly in patients with chronic constipation and recurrent volvulus, to ensure timely and appropriate surgical management.

Giant benign mesenteric cysts (mesothelioma and lymphangioma): A report of two cases

Introduction and importanceMesenteric cysts are a rare group of intra-abdominal tumors located in the mesentery or omentum, most of this lesion are asymptomatically but occasionally presents with non-specific symptoms, which makes diagnosis difficult. Case presentationWe present two cases of giant mesenteric cyst in our Institution, the first case is a women of 23 years with previous gynecologic surgery with chronic abdominal pain and large abdominal mass CT showed a giant intraabdominal 30 × 25 × 15 cm, the patient went to laparotomy and a large mesenteric tumor found. The Histopathology reported a Benign cyst mesothelioma (BCM). The second case is a 47 year male with intermittent abdominal pain and abdominal CT shows a 20x21x15 cm tumor. Laparotomy was performed. Histopathology reported a large lymphangioma. Clinical discussionBCM tumors are rare intrabdominal lesions often diagnosed in premenopausal women. Its etiopathogenesis is still unclear, associated risk factors are endometriosis, pelvic inflammatory disease and previous pelvic surgery. Lymphangiomas are an infrequent cyst tumors. It results from a failure in the evolutionary development of the lymphatic system, often localized in the head and neck and its localization in the abdomen is even rare. The definitive diagnosis is made by histopathology. ConclusionMesenteric cysts diagnosis if often challenge due to nonspecific symptoms and significant overlap in imaging appearance between the different entities, its diagnosis should be in mind when encounter a cystic abdominal tumor, surgical complete removal of this tumors is the optimal treatment to prevent recurrence and complications.

Robotic assisted excision of a mesenteric cyst of Müllerian origin in a 29-year-old woman

Mesenteric cysts are rare, benign tumors of uncertain etiology that require management. The Müllerian subtype of one of the rarer types of mesenteric cysts. Diagnosis of a mesenteric cyst typically involves nonspecific symptoms or an asymptomatic presentation. Treatment involves resection to prevent life-threatening complications. Resection through laparotomy surgery is the most common approach. The laparoscopic approach is gaining traction. We present a case in which a large mesenteric cyst was resected using a robotic assisted laparoscopic approach.

Removed: Giant mesenteric cysts: A rare case series with clinical insights

Introduction and significanceMesenteric cysts are rare, non-cancerous tumors found mainly in children. The symptoms can vary depending on the size and location of the cyst. While the exact cause is unknown, complete surgical removal is the main and most effective treatment for mesenteric cysts. Case presentationThree cases involving young boys were presented. They primarily complained of abdominal swelling without pain. Radiological tests revealed mesenteric cysts near the jejunum and transverse colon, and another near the sigmoid colon, which were both successfully removed. Clinical discussionDespite being uncommon, mesenteric cysts should be considered when diagnosing abdominal masses in children. ConclusionSurgical intervention is crucial for patients with mesenteric cysts. Complete surgical removal leads to a positive prognosis, even for large or complex cases. This stresses the importance of considering. Environmental factors are potential causes for the formation and development of these tumors.

Diagnostic Approach of Mesenteric Cyst in Children: A Case Report

Background: Mesenteric cysts are intra-abdominal masses that arise from obstructed lymphatic drainage within the mesentery. Early diagnosis can be challenging, as it is often difficult to recognize based solely on clinical findings. The diagnosis is frequently made following imaging studies or during surgery. Despite their generally benign nature, delayed diagnosis can lead to serious complications. This case report aims to share our experience on the diagnostic approach for mesenteric cysts in children. Case: A 2-year-old boy presented with a 14-month history of slowly progressive abdominal distension and signs of bowel obstruction, including weight loss. Abdominal ultrasound revealed thin-walled, well-demarcated, septated fluid sacs consistent with a cyst. Abdominal CT-Scan showed massive ascites filling the intraperitoneal cavity and pushing the intestine upward along the thickened mesentery, causing bowel obstruction. Histopathological examination confirmed the diagnosis of cyst lymphangioma derived from mesentery. The cyst was successfully excised via laparotomy, and histological examination confirmed it as a cystic lymphangioma. Discussion: Our diagnostic approach focused on exclusion of differential diagnosis for abdominal distention in children, including ascites, abdominal tuberculosis, mesenteric cysts, and intra-abdominal masses. The absence of constitutional symptoms and lack of response to anti-tuberculosis therapy made it an unlikely diagnosis. While the CT-scan suggested ascites, the ultrasound results suggested a mesenteric cyst. Despite its large size, a complete excision of the cyst was successfully performed via laparotomy. Conclusion: The nonspecific nature of mesenteric cysts often delays diagnosis, making abdominal ultrasound an essential initial imaging modality for patients suspected of having this condition.

Mesenteric cysts.

<b>Introduction:</b> Mesenteric cysts (MCs) are a rare pathology of the abdominal cavity (with an incidence of 1/27.000 to 1/250.000 admissions) and less than 1000 cases have been described in the specialized literature.<b>Aim:</b> To identify the characteristics of clinical manifestations, diagnostics, and treatment of MCs.<b>Materials and methods:</b> Within 2001-2017, 17 consecutive patients with MCs were observed. Ultrasound scan (n = 17), computed tomography (n = 15), and magnetic resonance imaging (n = 1) were used to diagnose MC.<b>Results:</b> The mean age of patients with MCs was 43.4 3.5 years (range from 19 to 67), with a significant predominance of women (n = 14, 82.4%). The main clinical symptoms of MCs included abdominal pain (n = 9, 52.9%), pain + abdominal discomfort (n = 4, 23.5%), abdominal pain + nausea (n = 2, 11.8%), and abdominal discomfort (n = 2, 11.8%). In 13 (76%) cases, a palpable mass was noted in the abdominal cavity. According to imaging studies, the largest size of the MCs was 12.1 1.2 cm (from 5 to 20 cm) and the smallest - 8.6 0.8 cm (from 4 to 15 cm). The density of MC contents by computed tomography data varied from 2 to 26 HU. All patients underwent surgery via laparotomy. MCs were significantly more often located in the mesentery of the large bowel (n = 14, 82.4%) as compared to the small intestine (n = 3, 17.6%). The MCs of the small intestine in all cases were located in the mesentery of the jejunum, whereas in the colon lesions, they were distributed as follows: cecum (n = 1, 7.1%), ascending colon (n = 3, 21.4%), transverse colon (n = 7, 50%), and sigmoid colon (n = 3, 21.4%). Most MCs (n = 16, 94.1%) were enucleated, and only in one case segmental resection of small intestine with MCs was performed. The histopathological examination revealed: simple mesothelial MC - in 8 (47.1%), simple lymphatic MC - in 7 (41.2%), and lymphangioma - in 2 (11.7%) cases.<b>Conclusions:</b> MC is a rare pathology of abdominal organs. The clinical manifestations of MCs are nonspecific, and the final diagnosis becomes apparent only during surgery. In most cases, it is possible to perform MC enucleation without long-term recurrences.

Mesenteric Cyst Masquerading as an Ovarian Cyst

Abstract Mesenteric cysts are rare benign abdominal lesions that possess the risk of malignant transformation in 3% of reported cases. Most cysts are asymptomatic and can affect practically any abdominal quadrant. They are diagnosed incidentally or during the management of their complications. Ultrasonography, computed tomography scan, magnetic resonance imaging and histopathology are needed for the diagnosis. They can mimic multiple other cysts; hence, their timely diagnosis is of utmost importance. The mainstay of treatment is surgical excision of the cyst, which is essential to prevent the recurrence of malignant transformation. We present a rare case of a 40-year-old female patient with no known comorbidities who started feeling weakness with gradual onset and was increasing. We successfully removed a mesenteric cyst of size approximately 10 cm × 6 cm × 5 cm. This article aims to educate the readers and to make fellow surgeons well aware of this condition for better diagnosis and treatment.

Coexistence of Cecal duplication cyst and Meckel’s diverticulum presenting as intestinal obstruction: A rare case report

Introduction and importance: Enteric duplication cyst (EDC) is a rare congenital anomaly with incidence of 1 in 4500 live birth. Meckel’s Diverticulum (MD) is the most common congenital anomaly of gastrointestinal (GI) tract. The coexistence of EDC and MD in same patient is extremely rare. Presentation of EDC depends on it’s location, may present with dysphagia, respiratory distress, abdominal pain, abdominal distension and intestinal obstruction. However, MD remains asymptomatic in most of the cases. Case presentation: We present a case of 11month boy, presenting with fever, vomiting, and abdominal distension for four days and decreased frequency of defecation with fowl smelling stool, not mixed with blood. All the systemic examination findings were regular except soft and generalized distension of abdomen. CECT scan of abdomen showed features suggestive of EDC versus mesenteric cyst. The patient underwent exploratory laparotomy with ileocecal resection, ileocolic anastomosis and appendectomy. Meckel’s diverticulum was discovered incidentally at distal ileum, and was left intact. The patient was discharged in stable state. Clinical discussion: EDCs can occur anywhere in the GI tract, most frequently in small intestine and least often in cecum. MD is true diverticulum of small intestine. This case report discusses a rare occurrence of a pediatric patient having both an EDC and MD, emphasizing diagnostic and management challenges in such unique cases. Conclusion: Clinicians should be aware about simultaneous occurrence of EDC and MD in pediatric population who may present as intestinal obstruction.

Primary Mesenteric Hydatid Cyst in Pediatric Patients: Case Report and Literature Review

Mesenteric hydatid cyst in children is not common, even in endemic areas. The primary or secondary origin of this site, especially in children, remains controversial. Secondary peritoneal hydatid cyst mainly results from spontaneous or traumatic rupture of concurrent liver cysts or leakage of cystic contents during surgery. The aim of our study is to present a mesenteric hydatid cyst in children. Our study focuses on a single case of a child with peritoneal hydatid cyst, who underwent surgery in 2021 in the pediatric surgery department of the Mohammed VI hospital in Marrakech. The diagnosis is based on abdominal ultrasound, computed tomography and hydatidosis serology. The treatment is surgical by open or laparoscopic excision, which can be associated with medical treatment.

Ileal Chylolymphatic Mesenteric Cyst in a 4-year-old Child

Abstract Mesenteric cysts are rare, usually asymptomatic intra-abdominal benign cystic lesions, located in gastrointestinal tract mesentery. Their incidence is estimated about 1/20,000 in the pediatric age group with a male-to-female ratio of 1:2. Here, we report a case of ileal chylolymphatic mesenteric cyst in a 4-year-old male child. A 4-year-old male child presented to the outpatient department with a history of on-and-off abdominal pain and vomiting for the last 2 years. Ultrasound revealed a well-defined anechoic area measuring approximately 68 mm × 52 mm in the lower abdomen and pelvis. Exploratory laparotomy was performed and excised cyst with an attached part of the ileum was sent for histopathology. Correlating histology with immunohistochemical findings, the final diagnosis of ileal chylolymphatic type mesenteric cyst was considered. Mesenteric cysts should be kept as a differential diagnosis of intra-abdominal and pelvic cystic lesions. Although rare, awareness of this entity is necessary for early and prompt diagnosis as well as management, particularly in patients of the pediatric age group.

Mesenteric root pseudocyst: finding in an asymptomatic patient—a case report

BackgroundMesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.Case presentationThis article describes the case report of an asymptomatic 28-year-old patient who presented a 6-cm abdominal cystic mass with mixed density, which was found incidentally by computed tomography. Exploratory laparoscopy was performed followed by conversion to conventional surgery to extract the tumor mass. The anatomical pathology diagnosis was pseudocyst of the mesentery root. Mesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.ConclusionsMesenteric cysts are rare, and their nonspecific symptoms often lead to diagnosis based on imaging findings. Complete laparoscopic enucleation is the standard treatment.

Travma Sonrası İnsidental Tespit Edilen Ekstrahepatik İntraabdominal Kist Hidatik: Olgu Sunumu

Hydatid cyst is a parasitic disease frequently encountered in the liver and lungs, caused by the larval form of Echinococcus granulosus. Occasionally, hydatid cysts can be seen in the spleen, kidney, heart, bone, ovaries and peritoneal cavity. We presented a case of extrahepatic intra-abdominal hydatid cyst, which we have detected incidentally in an eight-year-old girl who was investigated for post-traumatic abdominal pain. Radiologic examination of the patient showed a midline cystic mas including septations superior to the bladder, and mesenteric cyst, ovarian mass and hydatid cyst were considered for differential diagnosis. The indirect hemagglutination (IHA) test result of the patient was negative (

Laparoscopic Management of Multiple Liver, Omental, Mesenteric, Peritoneal, and Round Ligament Hydatid Cysts-A Rare Report of a Case and a Systematic Literature Review.

Hydatid cyst disease is a parasitic ailment with an endemic nature, predominantly affecting geographical areas with a tradition in animal husbandry. The most common localization of hydatid disease is in the liver (60%), followed by the lungs, with other organ localizations comprising less than 10%. The surgical approach to this condition can be carried out through open surgery or laparoscopy. The coexistence of hepatic and intraperitoneal hydatidosis often leads to the preference for open surgery. We performed a literature review aiming to retrieve data regarding demographic characteristics, clinical features, preoperative management, and surgical approach concerning these unusual localizations of hydatid disease. It was observed that the mesenteric localization frequently presented with acute abdominal pain (p = 0.038) and that the open approach was preferred in 85.71% of cases. Furthermore, an interdependence was identified between the localization of the cysts and the type of surgical approach (p = 0.001), with mesenteric localizations being approached through laparotomy and excision (p = 0.037), while omental localizations, due to the easier approach, benefited from laparoscopy with excision in 14.29% of cases. Overall, the laparoscopic approach was less frequently used, but its utilization resulted in a lower number of complications and faster recovery. Additionally, we present a rare case of hepatic and intra-abdominal hydatidosis, resolved exclusively through a laparoscopic approach, including a review of the literature for these uncommon localizations of hydatid disease. A 45-year-old patient diagnosed with multiple hydatid cysts, both hepatic and intraperitoneal, underwent surgical intervention with exploratory laparoscopy. Laparoscopic excision of peritoneal, epiploic, mesenteric cysts, and round ligament, along with laparoscopic inactivation, evacuation, and pericystectomy of hepatic hydatid cysts, was performed. The patient's recovery was uneventful, and she was reevaluated at 3 and 9 months without signs of recurrence. The association of hepatic hydatid cysts with multiple intra-abdominal localizations is not commonly encountered. The treatment of choice is surgical and is predominantly conducted through open surgery. The presented case is unique due to the exclusive laparoscopic approach in the management of mixed hepatic and intra-abdominal hydatidosis.

Congenital mesenteric cysts: rare but important entities in abdominal surgery

Mesenteric cysts are rare, benign, intra-abdominal tumors with an incidence of 1 case per 2,50,000 hospital admission. They present with non-specific clinical symptoms and signs which mostly lead to misdiagnosis. In many conditions mesenteric cysts are discovered either accidentally during radiological examination or during laparotomy for management of complications. Mesenteric cysts are usually non-cancerous and can be lined by different kinds of tissues. The exact cause of mesenteric cysts is not known, but there are various theories regarding it. In children they are considered as congenital i.e., due to abnormalities in development of embryonic mesentery and in adults it might be due to lymphatic malformation, occult trauma or infection. Treatment of mesenteric cyst includes enucleation or surgical excision depending on type of cyst. Since the case is very rare, pre-operative diagnosis and treatment is a challenge. We report a case of five-year-old female child with enterogenous mesenteric cyst in the small intestine. The differentials of ultrasound showed para ovarian cyst or mesenteric cyst. Abdominal computed tomography (CT) revealed an attached cystic mass at mesentery measuring 96×28×17 mm (CC×AP×AR). The child underwent exploratory laparotomy with cyst excision and intestinal resection with end-to-end anastomosis of small intestine. The knowledge about these cysts is important because many times they go undiagnosed and cause serious complications like rupture, torsion or intestinal obstruction.

Mesenteric and Omental Lymphatic Cysts in Children: A 23-Year Retrospective Descriptive Study from Central India

Introduction: Lymphatic cystic malformations occur in the mesentery of the small and large bowel, omentum and retroperitoneal area and are rare, benign, intra-abdominal cystic lesions. Aim: To review the demographics, clinical presentation and surgical outcomes of children’s mesenteric and omental lymphatic cystic lesions. Materials and Methods: A single-institution, retrospective descriptive study was conducted in the Department of Paediatric Surgery, Gandhi Medical College and Associated Hospitals, Bhopal, India, from January 1, 2000, to December 31, 2023. It included cases of lymphatic cystic lesions in infants and children below 12 years of age involving the mesentery of the small and large bowel and omentum. The details collected from the case records were the age, sex, clinical presentation, radiological investigations carried out, operative findings and the outcome of the operative intervention executed for mesenteric and omental lymphatic cysts in children. The results obtained from the present study are expressed in numbers and percentages. Results: The present study analysed 18 children aged ≤12 years who underwent surgery for lymphatic cysts of the mesentery of the small bowel (n=14), large bowel/mesocolon (n=1) and omentum (n=3) during the study period. There were 11 boys and 7 girls. More than four-fifths (n=15) of the children were ≤5 years old at the time of diagnosis and operative therapy provided. One-third (n=7) of the cases clinically presented with the clinical features of intestinal obstruction. The cysts involved the mesentery of the small bowel in three-fourths (n=14) of the cases. The complete excision of the lymphatic cysts was possible in three-fourths (n=14) of the cases. In 10 children, resection of the adjacent/involved small bowel segment was also required during the operative procedures. Fifty percentage of the cases revealed volvulus of the small bowel caused by mesenteric cysts involving the small bowel. More than half of the cases required resection of the adjacent/involved segment of the small bowel along with excision of the mesenteric cysts. Conclusion: Mesenteric cysts are rare abdominal pathology with diverse clinical presentations ranging from vague abdominal pain and lump to an acute abdomen. Early referral to higher centres, diagnosis and prompt surgical excision of the mesenteric cysts can prevent volvulus, one of the most common complications and requirements of an emergency surgical procedure.

Acute Abdomen Caused by Infected Mesenteric Cyst.

Teaching point: Computed tomography is essential for timely diagnosing infected mesenteric cysts as a cause of acute abdomen, ultimately requiring complete excision to confirm diagnosis given the potential of malignant transformation.

Mesenteric cyst in a newborn. A case report

We present a case report of a 1.5-month-old infant admitted to the Department of Paediatric Surgery on an elective basis in order to diagnose and treat an abdominal lesion identified in ultrasound examination during the prenatal period. Computed tomography with contrast of the abdominal cavity and pelvis showed a large abdominal cyst measuring 11 × 8 × 7 cm. Consequently, the child was referred for surgery. During the procedure, the cyst was completely dissected. Outside the abdominal cavity, it was decompressed from the blood-serous fluid. Intraoperatively, intestinal malrotation and right ovarian agenesis were additionally diagnosed. The material for histopathological examination was handed over in full. Microscopically, mesenteric lymphangioma was diagnosed.
