Are Computed Tomography Scans Necessary for the Diagnosis of Peritonsillar Abscess?

Background Peritonsillar abscess is one of the most common deep-space infections of the head and neck, accounting for significant healthcare costs in the United States. Contributing to this expenditure is the trend of increased usage of computed tomography (CT), particularly in the emergency department. However, CT can be falsely positive for peritonsillar abscess, prompting unnecessary drainage attempts that yield no purulence.

Low-Grade Appendiceal Mucinous Neoplasm: A Case Series.

Low-grade appendiceal mucinous neoplasm (LAMN) is a lesion of the appendix with potentially fatal consequences if untreated. Though LAMN can be asymptomatic and stable, it can rupture and seed mucin and neoplastic epithelium into the peritoneum, leading to pseudomyxoma peritonei (PMP), a serious complication characterized by intraperitoneal accumulation of mucinous tumors and ascites with a high morbidity and mortality rate. Therefore, timely identification and treatment of LAMN are crucial for reducing PMP risk and improving prognosis and outcome.
