Acute abdominal pain can represent a spectrum of conditions from benign and self-limited disease to surgical emergencies. Evaluating abdominal pain requires an approach that relies on the likelihood of disease, patient history, physical examination, laboratory tests, and imaging studies. The location of pain is a useful starting point and will guide further evaluation. For example, right lower quadrant pain strongly suggests appendicitis. Certain elements of the history and physical examination are helpful (e.g., constipation and abdominal distension strongly suggest bowel obstruction), whereas others are of little value (e.g., anorexia has little predictive value for appendicitis). The American College of Radiology has recommended different imaging studies for assessing abdominal pain based on pain location. Ultrasonography is recommended to assess right upper quadrant pain, and computed tomography is recommended for right and left lower quadrant pain. It is also important to consider special populations such as women, who are at risk of genitourinary disease, which may cause abdominal pain; and the elderly, who may present with atypical symptoms of a disease.

Emergency physicians and radiologists are increasingly confronted with aging HIV-positive or acquired immunodeficiency syndrome (AIDS) patients with acute abdominal symptoms, who often require immediate medical or surgical treatment. A wide spectrum of infectious and neoplastic HIV-related gastrointestinal diseases may be encountered, along with atypical presentations of common disorders. Since symptoms and physical findings are commonly nonspecific or masked by concurrent illnesses, medications, and weak immune response, prompt cross-sectional diagnostic imaging studies are needed to triage patients and choose treatment. Multidetector CT currently represents the mainstay modality to promptly investigate intra-abdominal opportunistic disorders in HIV/AIDS patients, and MRI is increasingly used to assess abnormalities involving the rectum. The spectrum of cross-sectional imaging appearances of HIV-related acute gastrointestinal disorders and complications observed in the antiretroviral era is reviewed, including acute intestinal infections, causes of right lower quadrant pain, bleeding, bowel obstruction, and perforation. State-of-the-art technology, knowledge of pertinent clinical information, and familiarity with the spectrum of opportunistic diseases are necessary to improve diagnostic confidence in the detection and characterization of gastrointestinal abnormalities on urgent cross-sectional abdominal studies performed in HIV-infected patients.

Acute right lower quadrant pain is a common, but nonspecific presenting symptom of a wide variety of diseases in children. Sonography (US) can play a significant role in the accurate and early diagnosis of right lower quadrant pain. In this article, we report a case of small bowel obstruction due to intestinal ascariasis diagnosed at bedside US and confirmed by MRI and describe a new US sign of intestinal ascariasis.

Kaposi's sarcoma was originally described by Moritz Kaposi in 1872 as a rare form of multiple hemorrhagic skin lesions. Today it is well documented as a systemic, multifocal, steadily progressive reticuloendothelial system tumor with a predilection for skin and visceral involvement. It occasionally presents as a visceral disease without skin manifestations. We report a case of Kaposi's sarcoma of the small bowel in a seropositive patient who presented with acute right lower quadrant pain and was diagnosed with intestinal obstruction with perforation on contrast-enhanced multidetector computed tomography (MDCT). The diagnosis was confirmed as Kaposi's sarcoma on postoperative histopathological analysis.
