[Show abstract][Hide abstract] ABSTRACT: Right lower quadrant abdominal pain is one of the most common causes of a patient visit to the emergency department. Although appendicitis is the most common condition requiring surgery in patients with abdominal pain, right lower quadrant pain can be indicative of a vast list of differential diagnoses and is thus a challenge for clinicians. Other causes of right lower quadrant pain beyond appendicitis include inflammatory and infectious conditions involving the ileocecal region; diverticulitis; malignancies; conditions affecting the epiploic appendages, omentum, and mesentery; and miscellaneous conditions. Multidetector computed tomography (CT) has emerged as the modality of choice for evaluation of patients with several acute traumatic and nontraumatic conditions causing right lower quadrant pain. Multidetector CT is an extremely useful noninvasive method for diagnosis and management of not only the most common causes such as appendicitis but also less common conditions.
[Show abstract][Hide abstract] ABSTRACT: PURPOSE/AIM
The purpose of this exhibit is: 1- To broaden the differential diagnosis of right lower quadrant abdominal pain on the emergency setting. 2- To demonstrate the ability of MDCT on the depiction of a wide range of conditions. 3- To review examples of uncommon causes of right lower quadrant pain, and also common causes with an atypical presetation.
Epidemiology of right lower quadrant pain Cases presentations and brief discussion: -Gastrointestinal Ileal, cecal and appendiceal acute diverticulitis, apendagitis of appendix and cecum, ileal limphoma, foreign bodies, bezoars, ruptured cecal cancer, carcinoid, endometriosis and mucocele on appendix, Crohn's disease, inguinal hernias and intussuception. -Genitourinay Ureteral calculi, ovarian torsion, ovarian teratoma, ruptured ectopic pregnancy, blader herniation through femoral hernia.
The major teaching points are: 1-Abdominal pain, specialy in the right lower quadrant, is a diagnostic challenge in the emergency setting due to a great number of possible differential diagnosis. 2-MDCT has emerged as the modality choice to evaluate acute abdominal pain. 3-Multiplanar reconstructions may be very usefull to depict and diagnose a broad range of pathologies.
