[Aspiration pneumonia diagnosed by esophageal transit SPECT/CT scintigraphy].

We present a 20-year-old male with agranulocytosis secondary to metimazole. The patient was admitted to intensive care unit (ICU) for sepsis, retrofaringeal abscess, and upper airway obstruction. Tracheal intubation and mechanical ventilation was used. Severe tetraparesia and critical illness polyneuropathy was developed while the patient was in the ICU requiring prolongedmechanical ventilation and tracheostomy. Once the patient improved, oral nutrition was started. However, repeated pneumonia was observed which required antibiotic therapy, so oral nutrition was stopped.
