We reviewed the 52 new cases of pulmonary tuberculosis diagnosed at Pusat Pakar Utara, Kedah in 1998. It was found that the majority of the patients had symptoms for many years. They had seen many doctors but were not diagnosed. In 40% of the patients, no investigations for tuberculosis were done and in the others tuberculosis was excluded because of negative sputum smear examination. Many had typical history and X-ray changes suggestive of tuberculosis but more sensitive investigations such as sputum culture for Mycobacterium or bronchoscopy were not performed. Cases are presented to illustrate the problems in the diagnosis.
