Jejunojejunal intussusception is infrequent in the adult. A 17 years old women presented a right lower quadrant pain since 24 hours. Under coelioscopy, jejunum was thickened, and hyperrontractible. Three jejunojejunal intussusceptions were discovered and ensily treated under coelioscopy. During post-operative days, fibroptic gastroscopy was normal, and the first jejunal segment was normal. Intestinal barium transit showed a dilated jejunal segment with thichened mucosa. Stools parasitology was negative. Three months later, patient was admitted with right lower quadrant pain recurrence. Coelioscopy did not show any intussusception. Appendectomy was undertaken. Histological analysis showed appendiceal oxyuris. The case described is characterised by three concomitant intussusceptions, the proximal jejunal site of the intussusceptions, the site of the pain distant from the intussusceptions, the occurrence in a young adult, the coelioscopic diagnosis, and the coelioscopic treatment. Diagnostic coelioscopy with complete exploration of the small intestine permit diagnosis and treatment under coelioscopy of jejunojejunal intussusception.

We describe an extremely rare case of an ileocolic intussusception with an appendiceal mucocele as the lead-point and cause of acute right lower quadrant pain in an adult patient. There are only few reported cases of this entity in the radiologic literature. We describe the multislice (computed tomography) CT features and emphasize the value of multiplanar reformations. We also discuss how specific findings on CT should allow for a correct preoperative diagnosis.

As with other types of endometriosis in the intestinal tract, endometriosis of the appendix is generally asymptomatic and is usually discovered incidentally during laparotomy in patients with pelvic endometriosis. When it presents with symptoms they are difficult to differentiate from acute appendicitis. Appendiceal endometriosis may not only cause symptoms of acute appendicitis, but may also present as cyclic and chronic right lower quadrant pain, melena, lower intestinal haemorrhage and caecal intussusception. We report a case of appendiceal endometriosis clinically presenting as acute appendicitis, where the definitive diagnosis was established by histopathological examination of the appendix.

Appendiceal mucoceles are rare cystic lesions with an incidence of 0.3-0.7% of all appendectomies. They are divided into four subgroups according to their histology. Even though the symptoms may vary - depending on the level of complication - from right lower quadrant pain, signs of intussusception, gastrointestinal bleeding to an acute abdomen with sepsis, most mucoceles are asymptomatic and found incidentally. We present the case of a 70-year-old patient with an incidentally found appendiceal mucocele. He was seen at the hospital for backache. The CT scan showed a vertebral fracture and a 7-cm appendiceal mass. A preoperative colonoscopy displayed several synchronous adenomas in the transverse and left colon with high-grade dysplasia. In order to lower the cancer risk of this patient, we performed a subtotal colectomy. The appendiceal mass showed no histopathological evidence of malignancy and no sign of perforation. The follow-up was therefore limited to 2 months. In this case, appendectomy would have been sufficient to treat the mucocele alone. The synchronous high-grade dysplastic adenomas were detected in the preoperative colonoscopy and determined the therapeutic approach. Generally, in the presence of positive lymph nodes, a right colectomy is the treatment of choice. In the histological presence of mucinous peritoneal carcinomatosis, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is indicated. In conclusion, mucoceles of the appendix are detected with high sensitivity by CT scan. If there is no evidence of synchronous tumor preoperatively and no peritoneal spillage, invasion or positive sentinel lymph nodes during surgery, a mucocele is adequately treated by appendectomy.

Three of the most common causes of surgical abdominal pain in pediatric patients include appendicitis, Meckel diverticulum, and intussusception. All 3 can present with right lower quadrant pain, and can lead to significant morbidity and even mortality. Although ultrasound is the preferred method of diagnosis with appendicitis and intussusception, considerable variety exists in the modalities needed in the diagnosis of Meckel diverticulum. This article discusses the pathways to diagnosis, the modes of treatment, and the continued areas of controversy.

In children presenting to the emergency room with right lower quadrant pain, ultrasound is the preferred initial modality. In our patient, a 6-year-old male with a sudden onset of severe right lower quadrant pain, the differential is broad, including appendicitis and intussusception. In order to narrow our differential and secure the diagnosis, our first modality was ultrasonography. With the increased use of point-of-care ultrasound in the emergency department, the diagnosis of appendicitis and ileo-colic intussusception has been made more frequently. In addition, other entities such as transient small bowel intussusception may be identified. As in our case, obstruction secondary to intussusception must be ruled out with observation, serial abdominal exams, clinical improvement, or further imaging.

Intussusception is rarely reported in adult patients with acute leukemia. We report a case of intussusception in a 29-year-old woman with acute myeloid leukemia (AML). She developed right lower quadrant pain, fever, and vomiting on day 16 of induction chemotherapy. Physical examination showed tenderness and guarding at the right lower quadrant of the abdomen. Abdominal computed tomography (CT) showed distension of the cecum and ascending colon, which were filled with loops of small bowel, and herniation of the ileocecal valve into the cecum. We proceeded to laparotomy and revealed ileocecal intussusception with the ileocecal valve as the leading point. The terminal ileum was thickened and invaginated into the cecum, which showed gangrenous changes. Right hemicolectomy was performed and microscopic examination of the colonic tissue showed infiltration of leukemic cells. The patient recovered after the operation and was subsequently able to continue treatment for AML. This case demonstrates that the diagnosis of intussusception is difficult because the presenting symptoms can be non-specific, but abdominal CT can be informative for preoperative diagnosis. Resection of the involved bowel is recommended when malignancy is suspected or confirmed. Intussusception should be considered in any leukemia patients presenting with acute abdomen. A high index of clinical suspicion is important for early diagnosis.

Right lower quadrant pain is a symptom with an exceptionally broad differential diagnosis. Intussusception of the appendix is a very uncommon condition with many manifestations. Additionally, the pathologic finding of ectopic presence of a mixture of at least two mullerian-derived tissue components is rare. This report presents the case of a 49-year-old woman who presented twice with acute right lower abdominal pain. Diagnosis of appendiceal inversion was made surgically. Pathologic examination of the specimen identified extensive endometriosis, endosalpingiosis and endocervicosis of the colon wall. Appendiceal intussusception and colonic mullerianosis, present together, are discussed, and recommendations for the diagnosis and treatment of appendiceal intussusception are discussed.

Appendiceal adenocarcinoma typically presents as an incidentally noted appendiceal mass, or with symptoms of right lower quadrant pain that can mimic appendicitis, but local involvement of adjacent organs is uncommon, particularly as the presenting sign. We report on a case of a primary appendiceal cancer initially diagnosed as a rectal polyp based on its appearance in the rectal lumen. The management of the patient was in keeping with standard practice for a rectal polyp, and the diagnosis of appendiceal adenocarcinoma was made intraoperatively. The operative strategy had to be adjusted due to this unexpected finding. Although there are published cases of appendiceal adenocarcinoma inducing intussusception and thus mimicking a cecal polyp, there are no reports in the literature describing invasion of the appendix through the rectal wall and thus mimicking a rectal polyp. The patient is a 75-year-old female who presented with spontaneous hematochezia and, on colonoscopy, was noted to have a rectal polyp that appeared to be located within a diverticulum. When endoscopic mucosal resection was not successful, she was referred to colorectal surgery for a low anterior resection. Preoperative imaging was notable for an enlarged appendix adjacent to the rectum. Intraoperatively, the appendix was found to be densely adherent to the right lateral rectal wall. An en bloc resection of the distal sigmoid colon, proximal rectum and appendix was performed, with pathology demonstrating appendiceal adenocarcinoma that invaded through the rectal wall. The prognosis in this type of malignancy weighs heavily on whether or not perforation and spread throughout the peritoneal cavity have occurred. In this unusual presentation, an en bloc resection is required for a complete resection and to minimize the risk of peritoneal spread. Unusual appearing polyps do not always originate from the bowel wall. Abnormal radiographic findings adjacent to an area of gastrointestinal pathology may signify locally advanced disease from a surrounding organ that secondarily involves the gastrointestinal tract. These findings warrant further investigation prior to any intervention to ensure appropriate treatment.

We present a rare case of intussusception in a 41-year-old man with acute myeloid leukemia without an evidence of leukemic infiltration of the bowel. The patient presented to the emergency room with right lower quadrant pain. Initially he was diagnosed with typhlitis. CT scan was done and showed ileocolic intussusception without a definitive lead point identified. Patient underwent hemicolectomy and histopathological study of the specimen did not show any leukemic infiltrate. High suspicion of intussusception should be kept in mind with leukemic patients presenting with abdominal pain.
