Complications of lymphoma in the abdomen and pelvis: clinical and imaging review.

Involvement of the abdomen and pelvis is common in lymphoma. Nodal and extranodal abdominal and pelvic lymphoma may present with various complications. Complications are most common in high-grade lymphomas, especially diffuse large B-cell lymphoma.

Chest computed tomography and chest X-ray in the diagnosis of community-acquired pneumonia: a retrospective observational study.

Objectives: To compare the yield of early combined use of chest X-ray (CXR) and chest computed tomography (CT) in patients diagnosed with community-acquired pneumonia (CAP) presenting to the emergency department (ED) and assess the impact of chest CT on the initial diagnosis.

Methods: The medical records of 900 patients who presented to the ED and were diagnosed with CAP over a 1-year period were reviewed, and 130 patients who underwent CXR and chest CT within 48 hours were selected. CXR findings were classified as positive, negative, or inconclusive for CAP.

Emergency room imaging in pediatric patients with cancer: analysis of the spectrum and frequency of imaging modalities and findings in a tertiary cancer center and their relationship with survival.

Background: To assess the spectrum and frequency of modalities used for emergency room (ER) imaging and their findings in pediatric cancer patients and assess their relationship with survival.

Methods: Consecutive pediatric cancer patients that underwent imaging during an ER visit at our tertiary cancer center over a 5-year period were retrospectively analyzed. Imaging findings were considered positive when they were relevant to the ER presenting complaint.

Functioning metastatic paraganglioma of the urinary bladder in a 10-year-old child.

Paragangliomas of the urinary bladder are very rare tumours representing less than 1% of bladder tumours. Preoperative diagnosis is essential to avoid perioperative complications related to catecholamine release. A high index of suspicion should be maintained when the classical symptoms of voiding-related paroxysms of headache, palpitation and dizziness are present.
