Abstract: A 37-year-old female presented with persistent dyspnea and syncope. Computed-tomography scan detected
saddle pulmonary embolism, and echocardiogram revealed extensive thrombus crossing the interatrial
septum and prolapsing across the mitral valve into the left ventricle. Consequently, the patient was treated
with surgical extraction of the thrombus and pulmonary embolectomy.
She was discharged after un-eventful hospital stay save a dark grey spot in her central vision, which
was diagnosed as homonymous paracentral scotoma caused by pre-operative cerebral infarction.Keywords: Impending paradoxical embolism, pulmonary embolism, homonymous paracentral scotoma
