Bradycardia symptomatic causes headache associated with frontal diffuse astrocytoma: a case report

Abstract

Background: Headache is the most common symptom in patients with brain tumors, whereas a developing brain tumor generally increases intracranial pressure and brain edema. Brain tumors have symptoms including nausea, vomiting, seizures, neurological deficits, and mental status or consciousness changes. Heart rhythm disturbances can occur, including bradycardia (heart rate below 60x/minute), a common symptom in brain tumor patients. Case Presentation: In this case report, a young adult male patient was found with headache symptoms, a previous history of syncope, and sinus bradycardia on the EKG examination, but on physical examination, there were no symptoms of neurological deficits. Head CT scan with contrast found a tumor in the left frontal lobe associated with high intracranial pressure and brain edema that explained the symptoms. Conclusion: The relationship between headache and bradycardia, accompanied by a history of syncope, is close and can be regarded as an early sign of a brain tumor. In this case, a brain tumor found based on pathological examination is diffuse astrocytoma.
