A Breathtaking Hernia: A Giant Hiatal Hernia Masquerading as Poorly Controlled Asthma

Abstract

A 93-year-old female presented with persistent shortness of breath and wheezing since the consumption of a meal. Her past medical history is significant for a clinical diagnosis of asthma at the age of 88 years, without pulmonary function testing, complicated by several prior visits to the emergency department (ED) for recurrent exacerbations. Multiple bronchodilators in the ED provided only minimal improvement in her symptoms. Chest imaging eventually revealed a giant, fluid-filled hiatal hernia exhibiting a compressive effect on the posterior aspect of the left atrium. The etiology of the patient's airway bronchoconstriction was likely multifactorial. We hypothesize that the extrinsic, dynamic compression of the bronchial tree by the peristaltic motion of the hiatal hernia, microaspiration from gastroesophageal reflux, and peribronchial edema from left atrial compression accounted for our patient's unique presentation. An outpatient methacholine challenge test eventually excluded bronchial asthma. Although she was considered a poor surgical candidate, she has had no further recurrences of her symptoms with counseling on conservative lifestyle changes. This case serves to highlight the heterogeneity in presentations of hiatal hernias, particularly in elderly females. Furthermore, it remains prudent to maintain a broad differential for wheezing, as evidenced by our patient who was previously managed for a number of years as poorly controlled asthma.
