Horner’s Syndrome and central venous obstruction are usually seen in patients with superior sulcus tumour, and their presence, especially in elderly patients, is alarming. Benign causes of Horner’s Syndrome and central venous obstruction are rare but well-documented in the literature. A combination of both occurring due to clavicular trauma is extremely rare. We report a case of an elderly male with clavicular trauma who presented with Horner’s Syndrome and central venous obstruction. He was managed conservatively and had a complete resolution of symptoms. This case highlights that even “red flag” clinical signs may represent relatively innocuous etiology, and thorough evaluation is essential before reaching a diagnosis.
