En route to the emergency department she also reported lightheadedness, a sense of impending doom, and nausea with 2 episodes of vomiting. In the emergency department she received intramuscular (IM) epinephrine
and intravenous (IV) antihistamines and steroids, and within 10 minutes her symptoms resolved.
This case underscores the high clinical suspicion that is often
required in identifying VCD, and the complexity of mimicry
that can exist in its presentation, including anaphylaxis.
