Unusual Cause of Persistent Chest Pain.

A 24-year-old female presented with a recent onset of left sided pleuritic chest pain especially when lying on her left side, causing disturbance in her sleep and daily activities. She was an enthusiastic athlete and was keen to get back to her cycling training. She had no history of trauma, and never smoked cigarettes. Apart from asthma, she did not have significant co-morbidities. She was investigated in 2012 for cervical lymphadenopathy. Fine needle aspiration of the lymph node raised the possibility of granulomatous inflammation. On clinical examination there was no swelling over the chest wall. The lung fields were resonant and clear. Her routine laboratory test results and spirometry were normal.
