EPIPLOIC APPENDAGITIS AS AN UNUSUAL CAUSE OF URGENT ABDOMINAL PATHOLOGY

Aim of the study is to present a clinical case of epiploic appendagitis as a rare acute abdominal pathology.Methods. This case demonstrates the prevalence of acute appendicitis symptoms in the clinical picture of the disease. During the operation was identified a necrotic changes in epiploic appendage of the ileocecal region with presence of secondary appendicitis.Result. The histological examination of the removed epiploic appendagitis gives a picture of tissues infarct with adipose necrosis and the presence of simple catarrhal appendicitis. It was received a normal postoperative course and a patient was discharged from hospital on the 8th day.Conclusion Epiploic appendagitis, due to the absence of pathognomonic symptoms, is an extremely difficult pathology for diagnosis. To establish the correct diagnosis, it is necessary to take into account a complex of data, including clinical and anamnestic, laboratory and instrumental diagnostic methods.

A Case Series on Epiploic Appendagitis: An Underdog in Acute Abdomen

Epiploic appendagitis is an uncommon yet a significant surgical diagnosis that every surgeon should be aware. It occurs due to the torsion of the epiploic appendage which gives rise to acute abdominal pain that can mimic other common causes of acute abdominal pain like appendicitis or cholecystitis. The treatment of epiploic appendagitis depend on clinical presentation, severity and it varies from conservative management to surgical excision. This case series is about eight patients presented with complaints of lower abdominal pain. After clinical examination they were initially diagnosed to have appendicitis or diverticulitis. The Computed Tomography (CT) -based diagnoses were appendicitis, omental infarct, diverticulitis or epiploic appendagitis. All of them were subjected to diagnostic laparoscopy and found to have an inflammed epiploic appendage which was excised laparoscopically.

CT imaging findings of epiploic appendagitis: an unusual cause of abdominal pain

Epiploic appendagitis is a rare cause of acute abdominal pain, determined by a benign self-limiting inflammation of the epiploic appendages. It may manifest with heterogeneous clinical presentations, mimicking other more severe entities responsible of acute abdominal pain, such as acute diverticulitis or appendicitis. Given its importance as clinical mimicker, imaging plays a crucial role to avoid inaccurate diagnosis that may lead to unnecessary hospitalization, antibiotic therapy, and surgery. CT represents the gold standard technique for the evaluation of patients with indeterminate acute abdominal pain. Imaging findings include the presence of an oval lesion with fat-attenuation surrounded by a thin hyperdense rim on CT (“hyperattenuating ring sign”) abutting anteriorly the large bowel, usually associated with inflammation of the adjacent mesentery. A central high-attenuation focus within the fatty lesion (“central dot sign”) can sometimes be observed and is indicative of a central thrombosed vein within the inflamed epiploic appendage. Rarely, epiploic appendagitis may be located within a hernia sac or attached to the vermiform appendix. Chronically infarcted epiploic appendage may detach, appearing as an intraperitoneal loose calcified body in the abdominal cavity. In this review, we aim to provide an overview of the clinical presentation and key imaging features that may help the radiologist to make an accurate diagnosis and guide the clinical management of those patients.

Mast cell deposition and activation may be a new explanation for epiploic appendagitis

Epiploic appendagitis is as an acute painful condition of the fat on the outside of the intestine. Thus far, there have been no publications to our knowledge that appendagitis can be caused by mast cells or can be associated with chronic pain. A patient with multisystemic disorders suffered with both chronic and acute attacks of abdominal pain for a year. The worst attack led to surgical resection of an enlarged sigmoid colon epiploic appendage. Careful review of her complex medical history and mast cell stains of gastrointestinal biopsies led to the diagnosis of mast cell activation syndrome. Re-examination of the resected appendage using an immunohistochemical stain demonstrated a high mast cell density which is a new histopathological finding. Treatment of mast cell activation syndrome and other related syndromes led to marked improvement in her health, including all types of chronic abdominal pain.

Closed Loop Obstruction from Epiploic Appendage Adhesion Mimicking Pericecal Internal Hernia

Internal hernias involve herniation of viscera into an abdominal compartment through a defect in the mesentery or peritoneum. Herniation may occur through normal anatomic structures or through pathologic defects secondary to congenital abnormality, inflammation, trauma, or surgery. Patients with an internal hernia most commonly present with acute bowel obstruction. While internal hernia is an uncommon cause of bowel obstruction, making up approximately 0.2-0.9% of cases (Choi, 2017), the incidence is increasing due to greater use of techniques such as Roux-en-Y for liver transplant and gastric bypass. There are multiple types of internal hernia, including paraduodenal, Foramen of Winslow, sigmoid mesocolon, pericecal, transmesenteric, transomental, supravesical, and pelvic. We present a case in which a transverse colon epiploic appendage adhesion to the ascending colon mesentery resulted in a closed loop obstruction mimicking a pericecal internal hernia. Radiologists should be aware of the imaging findings of closed loop obstruction related to internal hernia and maintain a high index of suspicion in patients with history of prior abdominal surgery presenting with bowel obstruction. It is useful for radiologists to understand that adhesions may result in internal hernias, which mimic the classically described categories.
