“…Spontaneous chylothorax with no apparent cause was reported in few cases, minimal physical activity or sudden head movement especially neck hyperextension was thought to be the precipitating factor along with recurrent vomiting, hiccups, and cough. 9,11 It was suggested that there should be a weak point from pre-existing disease to cause thoracic duct rupture with minimal exercise, reported cases had either active or previous TB infection, 9,13 the presence of positive QuantiFERON raise the possibility of latent TB which could have played a role in causing disruption of the thoracic duct. There was no evidence of active TB in our patient, and the spontaneous resolution of pleural fluid can support that.…”
