Abstract
Objective: To discuss the symptoms, diagnostic investigation, and follow-up of Fahr's syndrome, a rare neurological condition related to calcium deposit in areas of the cerebral parenchyma. Methods: This is a case study, conducted with a 74-year-old male. The data were obtained through your electronic medical record, analyzed, and compared with theoretical references. The study was approved by the Research Ethics Committee. Case details: The patient in question was admitted to a tertiary referral hospital after an episode of syncope, associated with intermittent vertigo, periods of hoarseness, difficulty in walking, headache, bradypsychism, weight loss, fever, and tremor in the limbs. A cranial tomography was performed, which showed calcifications in the cerebellum, thalamus and cerebral parenchyma, and laboratory investigation that revealed hypocalcemia and hyperphosphatemia, in addition to an extreme reduction of parathyroid hormone, suggesting the diagnosis of Fahr's syndrome caused by hypoparathyroidism. The patient was treated with calcium replacement and had a rapid improvement in symptoms. Final considerations: It is concluded that the knowledge of health professionals about the characteristics of brain calcifications, their clinical manifestations and appropriate treatment directly influences the patient's morbidity.
