Acute appendicitis remains one of the most difficult diagnoses to make in the Emergency Department. We present a puzzling and unusual case. A 47-year-old man had several hours of acute abdominal pain in the right upper quadrant, point tenderness in the right midquadrant on examination, and normal chemistries. Early appendicitis was suspected and a computed tomography (CT) scan of the abdomen was obtained. Appendicitis was not seen. What was evident was a retroperitoneal lipoma estimated to weigh 10 pounds. The general surgeon was consulted who believed that operation was necessary in light of the patient's continuing abdominal pain and the presence of the mass. Masses this large could cause pain from local compression of structures, or ischemia of the mass from outgrowing its blood supply. In surgery, a lipoma was observed that filled most of the retroperitoneum and displaced all the contents of the abdomen, including the cecum and its appendix. Also present was an acute appendicitis. On retrospective analysis of the CT scan, the appendicitis was evident but atypically located in the epigastrium. This case illustrates once again that the CT scan is a useful diagnostic adjunct for the diagnosis of new onset abdominal pain and specifically for appendicitis.

Torsions are rare acute abdominal conditions and are mistaken for other more frequent diseases. The present work draws attention to the most frequent diagnostic errors. The authors present three cases of torsions of intraabdominal organs and two cases of testicular torsion. All patients attended their doctor because of abdominal pain. In four of five cases the patients were first treated for an erroneous diagnosis of acute abdomen. In the first case the torsion of the omentum was mistaken for diverticulitis of the sigmoid, later for an intraperitoneal lipoma, in he second case for cholecystitis, in the third case a patient with torsion of a myoma was indicated for surgery on account of acute appendicitis. In the fourth case incomplete torsion of the testis was mistaken for irritation of the appendix. In the fifth case where abdominal symptomatology dominated the correct diagnosis of testicular torsion was made and atypically spontaneous detorsion of the testis occurred.

Myelolipoma is a relatively rare benign tumor composed of fatty tissue and bone marrow elements. It is frequently associated with the adrenal glands but may exist as a solitary mass elsewhere. Adrenal myelolipomas are typically nonfunctioning and asymptomatic. They may be associated with an endocrine disorder such as Cushing's disease, Addison's disease, or hyperaldosteronism; however they are most often discovered incidentally. Their size is usually less than 5 cm and they are managed nonoperatively. We report a case of bilateral giant adrenal myelolipoma producing abdominal pain in a 54-year-old man, who presented to his primary care physician with complaints of right shoulder pain with vague abdominal discomfort. Imaging studies identified bilateral suprarenal masses measuring 12 x 14 cm on the right and 8 x 10 cm on the left. These masses were consistent with fatty tissue radiographically. In addition a focal 5 x 4-cm mass was identified in the transverse colon. Because the patient was symptomatic and a diagnosis of liposarcoma could not be excluded he was taken to the operating room for exploratory laparotomy with excision of the masses and a transverse colectomy. Final histologic analysis identified bilateral adrenal myelolipomas and a solitary lipoma of the transverse colon. His postoperative course was uneventful with relief of the pain. Despite its benign nature and rare growth beyond 5 cm myelolipoma of the adrenal gland is best managed with excision in the symptomatic patient. Preservation of adrenal tissue is vital so as not to commit patients to a lifetime of steroid replacement.

Colonic lipomata are rare and mostly asymptomatic lesions; but as they become larger they may produce abdominal pain, constipation, diarrhea, hemorrhage, and intussusception. We report the case of a 75-year-old man who suffered from nonspecific recurrent abdominal pain in the left upper and lower quadrants and had variable episodes of diarrhea and constipation of 4 weeks' duration. During colonoscopy, a giant intraluminal polyp was diagnosed at 35 cm. Abdominal helical computed tomography (CT) revealed a constipating colonic tumor with a diameter of >or=50 mm and density values equal to fat. During laparoscopic surgery in the lithotomy position, the sigmoid and the descending colon were mobilized using a Harmonic scalpel. The origin of the polyp was localized precisely under colonoscopic guidance. The former 12-mm incision in the left lower quadrant was expanded to approximately 70 mm for extracorporal tumor resection. The left and sigmoid colon resections were carried out, and the polyp was removed by full-wall excision. After closure with a single-layer suture, the colon was pushed back into the peritoneal cavity. The patient had an uneventful recovery and was discharged 10 days postoperatively. Histology confirmed a benign lipoma of the descending colon. Laparoscopic-assisted resection under endoscopic guidance proved to be suitable for the removal of large colonic polyps without complications.

Mesenteric lipoma is a rare benign neoplastic condition that can grow to be very large and mimic other midgut fatty tumors. These benign tumors can cause various gastrointestinal symptoms such as obstruction and abdominal pain. We report the case of a 9-year-old boy who presented with a small bowel obstruction caused by torsion of a large mesenteric lipoma. This is an important but unusual tumor and should be considered in the differential of fatty lesions within the mesentery.

The authors present 6 cases of colonic lipoma, 2 in females and 1 in male, aged between 61-62 years. The benign lipomatous tumour was in all cases unique, located in the right segment of the colon, ileocecal valve, and on the sigmoid once respectively. The right colonic lipomas had clinical signs of intestinal invagination while the sigmoidian one were characterized by abdominal pain and bleeding. The surgical solution consisted in limited ileocecal resection, right hemicolectomy, and segmentary colectomy respectively.

Mesenteric lipoma is a rare benign tumor of mature fat cells. Although generally asymptomatic, it occasionally causes abdominal pain, ileus, and small bowel volvulus, depending on its location and size. A definitive diagnosis can be made by pathological examination. Ultrasonography and abdominal computed tomography show this lesion as a well-defined, homogeneous mass with fat density surrounded by a thin capsule. Because of its rare etiologic origin, we report the case of a 7-year-old girl with a mass in the abdomen and ileus, found to be caused by a mesenteric lipoma.

We report an unusual presentation of multiple endocrine neoplasia type 1 (MEN 1) in a young woman who was subsequently proven to have a novel mutation of the MEN1 gene. The young patient, aged 25 years, was investigated for abdominal discomfort and left upper abdominal pain. Her family history was unremarkable, except an unknown disorder of her father causing early death. Abdominal ultrasonography (USG) and computed tomography revealed a giant pancreatic tumor measuring 10 cm in diameter. The diagnosis of a clinically nonfunctioning pancreatic neuroendocrine tumor was established by clinical and other studies, including USG-guided aspiration biopsy and octreotide scintigraphy, and the patient underwent a distal pancreatectomy. Histology proved a well-differentiated multinodular neuroendocrine tumor of the pancreas. During surgery, a subcutaneous lipoma was also removed from the abdominal wall. Two years later, the patient developed primary hyperparathyroidism, and two enlarged parathyroid glands were surgically removed. Magnetic resonance imaging of the pituitary gland was normal. Screening for MEN1 gene mutation by temperature gradient gel electrophoresis revealed heterozygosities in exons 3, 8, and 9, while direct sequencing indicated a novel germline mutation (C354X) resulting in a stop codon in exon 8 and polymorphisms in exon 3 (R171Q) and exon 9 (D418D and L432L). Genetic screening revealed no mutation in living family members. Our unusual case suggests that a multinodular pancreatic neuroendocrine tumor in a young patient may justify screening for MEN 1 syndrome, even in the absence of other endocrinopathy or family history.

Left colonic antegrade continence enema (ACE) has been reported only as an alternative to right colonic ACE-the Malone appendicostomy and Monti retubularized ileostomy. This paper evaluated the advantages of left colonic ACE using a retubularized sigmoidostomy (RS) as an appropriate method for maintaining fecal continence and as a first-line surgical treatment for patients with fecal incontinence or intractable constipation. Ten patients underwent surgery between March 2002 and June 2003: seven with meningomyelocele, one with cloacal anomaly, one with anorectal malformation, and one with lipoma of the spine. An RS tube was fashioned and then implanted using a segment of the sigmoid colon and exteriorized through the umbilicus. An enema was done 10 days after surgery using only normal saline. The outcomes were assessed after adjusting to the appropriate enema regimen for the 10 cases. The mean duration of the enema was 23.0+/-8.4 min, with 250 ml (range 80-800) as the median volume of fluid used. The enema interval ranged from 1-3 days. No patient showed any abdominal discomfort or soiling episodes, with the exception of one who experienced daytime fecal staining, but this occurred less than once per month. The self-cosmesis for the umbilical stoma was satisfactory. The RS procedure provided excellent continence control, with a shortening of the enema duration, a lower fluid volume, and good cosmesis, and without any ACE-related abdominal pain. This procedure can be used as a first-choice surgical treatment for intractable constipation and fecal incontinence.

We present a young woman who was hospitalized for abdominal pain and vomiting. Abdominal CT revealed diagnostic features of ileoileal intussusception with a central hypodense lesion of fat density suggestive of a lipoma as the lead point. This diagnosis was confirmed at surgery, where a small bowel resection was performed and a benign lipoma of the ileum was found.
