Further questioning and examination in the department revealed a classical Horner’s syndrome; miosis, partial ptosis and hemifacial anhidrosis. An initial chest X-ray was deemed to be unremarkable; however, further review by a radiologist noted asymmetrical right apical thickening. A subsequent high-resolution CT scan of the chest revealed a right-sided Pancoast tumour. This case highlights the importance of a thorough history and examination in identifying a rare cause of shoulder and/or back pain. ER -
