There is a wide variety of uncommon and unusual gastrointestinal causes of acute abdominal and pelvic pain that may be prospectively diagnosed on computed tomography. We demonstrate 10 such diagnoses and briefly review the current computed tomography and clinical literature on intussusception occurring beyond early childhood, small bowel obstruction from internal hernia, cecal volvulus, intramural small bowel hemorrhage, Boerhaave's syndrome, gastrointestinal luminal foreign bodies, small bowel diverticulitis, hemoperitoneum secondary to abdominal tumor; gallstone ileus, and gallbladder torsion. Radiologists and clinicians need to be aware of these disorders, particularly with the widespread utilization of computed tomography (CT) in the management of patients with acute abdominal pain.

An 86-year-old woman was admitted to the hospital to undergo an examination for tarry stools. Laboratory tests showed hypoproteinemia and renal dysfunction. Upper gastrointestinal endoscopy demonstrated a type 5 tumor located in the upper body of the stomach. An upper gastrointestinal series and computed tomography revealed an organoaxial gastric volvulus and the dislocation of the proximal stomach through an esophageal hiatal hernia. The preoperative diagnosis was the incarceration of a gastric carcinoma arising from the proximal stomach with an organoaxial gastric volvulus through an esophageal hiatal hernia. A total gastrectomy and hernia repair were performed. A microscopic examination of the surgical specimen revealed a gastric large cell neuroendocrine carcinoma (GLCNEC). The patient was discharged 22 days after the surgery. Although the prognosis of GLCNEC is significantly worse than that of a conventional adenocarcinoma, the patient was doing well without recurrence at 15 months after surgery. The details of this case are reported with some bibliographical comments.

Mesenteric lipoblastoma is a rare tumor and, its presentation as a bowel obstruction with possible midgut volvulus has only been reported once before. A 7-year-old girl presented with nausea and vomiting but a benign abdominal examination. Upper gastrointestinal contrast study demonstrated possible malrotation with midgut volvulus. During emergency laparotomy, segmental small bowel volvulus secondary to a large mesenteric lipoblastoma was found. The lipoblastoma was resected with a segment of small bowel. Resection margins were negative for tumor, and the patient is doing well with no evidence of recurrence.

Mesenteric cysts are lesions that appear very rare. Its incidence ranges from 1:20,000 in children and 1:100,000 in adults. Their clinical manifestations are atypical and they include abdominal pain, vomit, tumor and complications from hemorrhage, peritonitis when there is a rupture of infected cyst, intestinal occlusion, renal failure, volvulus and malignant transformation. We present a case of mesenteric cyst, located in the mesoappendix with slight vascular compromise and chronic symptoms, its treatment and evolution.

Peutz-Jeghers syndrome (PJS), which is characterized by multiple hamartomatous polyps of the gastrointestinal tract and mucocutaneous pigmentation, is a rare autosomal dominant disease. This syndrome is often represented as a surgical emergency with complications of the polyps such as intussusception, small bowel obstruction, bleeding, and volvulus. In particular, many studies have reported that patients with this syndrome have a high risk of gastrointestinal or extragastrointestinal malignancy including gastric, duodenal, jejunal, ileal, and colonic carcinoma as well as malignancies involving other organs such as the gallbladder, biliary tract, pancreas, tonsils, breast, and reproductive system. However, there are few reported cases of an association of this syndrome with extraintestinal malignancy. In addition to that, there is no reported case of this syndrome with malignant tumor or intraductal papillary mucinous tumor of pancreas in Korea. We experienced a case of PJS accompanying intraductal papillary mucinous carcinoma of the pancreas, therefore we report this case with literatures reviewed.

Up to 5% of untreated female Onchocerca volvulus filariae develop potentially fatal pleomorphic neoplasms, whose incidence is increased following ivermectin treatment. We studied the occurrence of 8 filarial proteins and of Wolbachia endobacteria in the tumor cells. Onchocercomas from patients, untreated and treated with antibiotics and anthelminthics, were examined by immunohistology. Neoplasms were diagnosed in 112 of 3587 female and in 2 of 1570 male O. volvulus. The following proteins and other compounds of O. volvulus were expressed in the cells of the neoplasms: glutathione S-transferase 1, lysosomal aspartic protease, cAMP-dependent protein kinase, alpha-enolase, aspartate aminotransferase, ankyrin E1, tropomyosin, heat shock protein 60, transforming growth factor-beta, and prostaglandin E(2). These findings prove the filarial origin of the neoplasms and confirm the pleomorphism of the tumor cells. Signs indicating malignancy of the neoplasms are described. Wolbachia were observed in the hypodermis, oocytes, and embryos of tumor-harbouring filariae using antibodies against Wolbachia surface protein, Wolbachia HtrA-type serine protease, and Wolbachia aspartate aminotransferase. In contrast, Wolbachia were not found in the cells of the neoplasms. Further, neoplasm-containing worms were not observed after more than 10 months after the start of sufficient treatment with doxycycline or doxycycline plus ivermectin.

Mesenteric cysts (MC) are a rare surgical condition occurring approximately in 1/200.000-350.000. The aetiology is unknown and the rarity of the tumor has led to confusion about their nature and classifi cation. They can be uni- or multi-locular, and are mostly benign. Approximately 830 cases have been reported in the literature and only four of them were found to be malignant. Cysts are usually diagnosed during routine abdominal examinations, they can present with various signs, such as acute abdominal pain, chronic abdominal pain, nausea and vomiting, or change in bowel habit. Although rare, shock due to rupture or bleeding of the cyst, intestinal obstruction secondary to external compression and volvulus or torsion of the cyst have been reported. Defi nitive treatment requires complete surgical resection of the cyst and is indicated when the lesion causes symptoms. We report a case of calcifi ed MC which was completely excised using the laparoscopic approach.

A rare case of mucinous adenocarcinoma of the cecum in a pregnant woman is described. A 32-year-old Korean woman was diagnosed as having an abdominal tumor immediately after giving birth. Abdominal computed tomography demonstrated a smooth mass measuring 10 cm in diameter on the right side of the abdomen. Acute abdomen developed 3 days after birth. At emergency surgery, volvulus of a polypoid tumor was detected at the cecum apart from the normal appendix. We successfully performed a tumorectomy; however, histopathological examination demonstrated mucinous adenocarcinoma with a massive blood clot.

Lymphangiomas are congenital malformations of the lymphatic system that account for about 5% of all benign tumors in infants and children.(1) The most common sites are the neck and axilla, which account for 95% of cases.(2) Abdominal cystic lymphangiomas are quite rare, and can arise from either the retroperitoneum, gastrointestinal tract, or the mesentery of the abdominal viscera.(3) The presenting symptoms are painless abdominal distension, a palpable mass, or secondary complications in the abdomen such as intestinal obstruction, volvulus, intestinal infarction, or bleeding.(4) Typically diagnosed during childhood, these tumors prompt surgical intervention. We describe an atypical case of an abdominal cystic lymphangioma, which did not manifest until adulthood, with atypical symptoms of a rapidly expanding and symptomatic mass.

Transplant-transmitted malignances are rare but devastating events. Primary brain tumors are the least common among reported donor-derived malignancies. We report a case of donor-transmitted pineoblastoma, a PNET, in a two-yr-old male recipient, who presented with a rapidly growing mass in the right mandible, four months after multiple visceral organ transplantation. The recipient had liver, pancreas, and small bowel transplants because of end-stage liver failure and short gut syndrome, which was secondary to large bowel resection for management of gastroschisis complicated by intestinal volvulus. The donor autopsy results became available seven wk after transplantation, which found a pineoblastoma with meningeal spread. Evaluation of eyes, adrenal glands, bone marrow, and other organs did not identify metastasis outside the CNS. A biopsy of the recipient's right mandibular mass revealed a malignant small round blue cell tumor with the immunohistochemistry profile of a PNET. Staging evaluation revealed the tumor in the right mandible with bone marrow involvement. Further investigation showed that recipient's tumor and donor's pineoblastoma shared the same immunophenotype and HLA type, suggesting the recipient's tumor is a donor-transmitted pineoblastoma. This is the first case report of donor-transmitted pineoblastoma post-organ transplant.
