Acute Intratonsillar Abscess in an Adult: A Case Report and Literature Review.

Intratonsillar abscess (ITA) is rarely reported. Here, we present an uncommon case of acute ITA in an adult, discuss the evaluation and treatment plan, and review the ITA literature.  The abscess reported in the present study was diagnosed through a combination of clinical findings and computed tomography imaging, and treatment included drainage, intravenous (IV) clindamycin, and IV dexamethasone. The literature reports 72 ITA cases with specified treatments: 21 (29.2%) in adults, 19 (26.4%) in children, and 32 (44.4%) in patients of unspecified ages. Among them, 25 (34.7%) responded to antibiotics alone, 11 (15.3%) to needle aspiration and antibiotics, and 36 (50.0%) needed further intervention. Based on the presented case and literature review, we suggest the use of IV antibiotics with needle aspiration as the primary treatment for acute ITA. Incision and drainage (I&D) with antibiotics should be reserved for cases unresponsive to initial measures, and tonsillectomy is recommended for recurrent post-I&D cases.
