In the right lower lobar bronchus, a hyperdense round foreign body was noted (arrow).
Bronchoscopy shows no definite foreign body but black pigmentation and severe endobronchial inflammation were noted in the bronchus.
Biopsy specimen revealed iron deposition, this case was considered as inflammation induced by aspiration of a ferrous sulfate tablet.
Aspiration of a ferrous sulfate tablet is a medical emergency that requires prompt recognition and removal because ferrous sulfate rapidly dissolves within the airway and produces substantial mucosal inflammation, necrosis, and potentially severe bronchial stenosis. Clinically, a detailed history is important for diagnosing aspiration of a ferrous sulfate tablet. High attenuation foreign body on CT may be helpful for diagnosis but not specific for ferrous sulfate. slot deposit pulsa 5000
