Background: Omental torsion is an uncommon cause of an acute abdomen. Most often it presents with sign and symptoms of acute appendicitis. We report this case to reveal the clinical presentation and computed tomography imagine findings of omental torsion as an uncommon cause of abdominal pain. case report: A 45-year-old male presented to the emergency department complaining of right lower abdominal pain. There was no pathological sign except millimetric stones in the gall bladder and free fluid in the right lower quadrant in abdominal ultrasonography. Then computed tomography was performed and it shoved omental whirl sign and increased density in great omentum consistent with omental torsion. Thus, a diagnosis of omental torsion was made immediately, which was confirmed by subsequent surgery. conclusion: Omental torsion is a rare cause of acute abdominal pain, but especially it will be remembered for patients with unclear symptoms and nonspecific abdominal pain.
Lymphocyst is mainly observed following extraperitoneal surgery. In this retrospective study, we aimed to determine the results of patients treated with percutaneous catheter drainage who referred to the emergency department due to lymphocyst complications. The examined group was consisted of 17 patients. All patients admitted to the emergency were suffering from abdominal pain. Ultrasonography (USG) was performed to all patients. Computerized tomography (CT) and magnetic resonance ımaging (MRI) were performed in 13 and 1 patient respectively. With the imaging evaluation complicated lymphocysts were detected. In 5 cases compression of urinary bladder, in 5 cases hydroureteronephrosis, in 2 cases compression of the left external iliac vein, in 1 case compression of the small and large intestine were observed. Percutaneous catheter drainage and sclerotherapy under ultrasonography and fluoroscopy guildance was performed to all cases in interventional radiology unit. To the best of our knowledge most of the lymphocysts were asymptomatic.Complicated lymphocysts may present as acute abdominal pain due to intraabdominal mass effect in patients having undergone surgery for gynecologic malignancy. If the lymphocyst is infected or becomes symptomatic due to compression of adjacent organ must be diagnosed and treated in early period. Clinical and radiological examinations are the key to the diagnosis of complicated lymphocyst. Emergency physicians should consider percutaneus catheter drainage as a treatment of choice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
