A 59-year-old woman treated chronically with enalapril, an angiotensin-converting enzyme inhibitor (ACE-I) presented with difficult swallowing and speaking. Although her symptoms were clinically consistent with an adverse angioedema reaction to the ACE-I, initial imaging was not entirely consistent with our conceptual understanding of angioedema. This case report will discuss the myriad possible imaging presentations of this disease, as well as the differential diagnosis for this atypical manifestation of ACE-I-induced angioedema.
