Cavitary Pulmonary Tuberculosis in an Infant: A Diagnostic Dilemma.
J Pioneering Med Students Jan ;4(3):112-4.

Cavitary pulmonary tuberculosis (TB) is extremely rare in infancy. Cavitation in lung in an infant usually suggests the diagnosis of staphylococcal pneumonia or congenital anomaly. Here we are reporting a 7 month, BCG vaccinated infant who presented with high-grade fever and cavitation on the chest x-ray. Reverse contact tracing did not reveal TB in parents or close relatives. We established the diagnosis of tuberculosis by demonstrating acid-fast bacilli in his gastric aspirate by smear and culture. We suggest that even in absence of suggestive history of TB, early morning gastric aspirate should be examined in all cases of non-resolving cavities in infants.
