Diagnose of occult bronchial foreign body: A rare case report of undetected Chinese medicine aspiration for 10 long years.
Paraules clau
Resum
BACKGROUND
Occult bronchial foreign body can be very difficult to diagnose early in an adult patient without acute symptoms. This report describes a rare case of undetected Chinese medicine "Coptis chinensis" aspiration for 10 long years.
METHODS
A case was reported that a female patient complained of a 10-year history of productive cough. A battery of tests were given to confirm the diagnosis.
RESULTS
Chest computed tomography (CT) showed extensive bronchiectasis and multiple nodules, along with stenosis of left lower lobar bronchus. An extensive solid lesion with surrounding inflammatory granulation tissue was seen on her first bronchoscopy and biopsy revealed chronic mucosal inflammation. A neglected history of Coptis chinensis regularly kept in-mouth while sleeping for the last 10 years in this patient provided clues for a final diagnosis. Confirmatory diagnosis of bilateral tracheobronchial foreign bodies caused by recurrent inhalation of Coptis chinensis was made by a second bronchoscopy.
CONCLUSIONS
This case clearly demonstrates that a precise medical history is often overlooked. A high index of suspicion, a precise medical history, radiographic features of chronic respiratory symptoms not explained by other conditions were keys to diagnosing this case.
