At just 18 years old, Rehan (name changed) faced an unexpected stroke, with no prior history of heart disease or risk factors. Initially diagnosed with a blockage in the left middle cerebral artery, further investigation revealed a large left atrial myxoma, a type of benign heart tumor, which had been silently releasing fragments into his bloodstream, leading to the stroke. Dr. Atanu Saha, a senior cardiac surgeon at Narayana RN Tagore Hospital in Kolkata, performed a complex five-hour surgery to remove the tumor. Post-surgery, Rehan underwent neuro-rehabilitation and has since made significant progress, returning to a normal life and pursuing his dream of becoming a doctor. This case underscores the rarity of cardiac myxomas in adolescents and the importance of early imaging and awareness of stroke symptoms in younger patients. Cardiac myxomas account for nearly half of all primary benign heart tumors, yet they often go undetected until serious complications arise. The case highlights a shift in stroke epidemiology, with increasing occurrences in younger adults, necessitating timely medical attention for unexplained neurological symptoms.
