A 63 year-old male patient goes to the doctor as bloody sputum coughing for some days with feeling of suffocation. There was no pathological sign or symptom of other organs. Inflammed blood tests, and coagulation tests were in normal range.
His wife and his familial doctor also want having a bronchoscopy for the patient at MEDIC.
3 days later, patient no longer spitted bloody
sputum, and completely seems to be healthy. The pulmonologist decided to repeat chest CT and virtual bronchoscopy for the patient. Chest CT at MEDIC showed tracheal
lesion disappeared.
DISCUSSION:
Characteristics to detect a mucus
secretion in trachea:
• Small
size.
• At
posterior wall of trachea (supine position during CT scan procedure).
• Small
air shadow within the nodule suggesting mucus secretion.
• It
will be transformed or disappeared after coughing.
CONCLUSION:
Mucus secretion in trachea can be mistaken with endoluminal
trachea tumor.
Their characteristics on chest CT should be put under caution. And a repeated CT scan made after coughing may help detecting a mucus secretion. Thanks of that we could avoid unnecessary invasive procedure for patient.
A case with chest CT showed multiple nodular
lesions that were both upper lobes, indicated a pulmonary tuberculosis. And it existed a small
nodule at posterior wall of trachea. After coughing, repeated CT scan showed the nodule of trachea disappeared.
