TB or Not TB, That is the Question?

Abstract

A 26-year-old female presented with a 3-month history of dry cough, unintentional weight loss, night sweats and fatigue. Her background history was significant for ulcerative colitis, managed with Adalimumab for almost 2 years. Clinical examination was unremarkable, apart from some mild pallor. Abnormal chest x-ray findings prompted a computerised tomography (CT) thorax which demonstrated multifocal peri-bronchial consolidation. The differential diagnosis was multifocal organising pneumonia and tuberculosis (TB). Extensive investigations, including invasive bronchial imaging and biopsy, ultimately ruled out TB. This paper reports a case of Adalimumab-induced organising pneumonia and discusses its clinical implications.
