Highlights a rare presentation of lung cancer invading the left atrium via the pulmonary vein and causing an ipsilateral stroke.
Clinicians should consider pulmonary vein invasion in lung cancer with ipsilateral stroke; hypothesis-generating and should not yet change practice.
Left atrial invasion by lung cancer via haematogenous pathways is a relatively uncommon but potentially life-threatening event. While several cardiac complications of cardiac involvement have been previously described, the evolution towards cerebral stroke has been rarely reported. In this case report, we describe an atypical case of haematogenous metastatic invasion of the left atrium from pulmonary neoplasm extension presenting as an ipsilateral stroke whose ASCO classification changed during the clinical management.
