“…The most common neurological symptoms are headache, vertigo, movement disorders (such as Parkinson's tremor, dystonia, and cerebellar ataxia), myoclonus and seizures [1]. Other neurological symptoms consist of stroke like events, speech disorders, coma, cognitive impairment, and syncope [1,6,7,15,16]. The psychiatric symptoms are usually more prominent than the neurologic symptoms in the onset of the disease [4,5].…”

“…The most common cause of HPT is inadvertent damage or removal of the parathyroid glands during thyroidectomy [6,8,19,20]. After total thyroidectomy, transient HPT can be observed in as high as 10% of patients.…”

“…Most of these patients recover parathyroid function within several months, however about 4.4% develop permanent HPT [8]. In postoperative HPT, BGC will develop in untreated patients after a median of 17 years [6].…”

“…The clinical manifestations can be paresthesias, seizures, myoclonus, tetany, parkinsonism, and neuropsychiatric disorders (such as cognitive and psychotic disorders) [1,[5][6][7]. Early treatment, if instituted correctly, can reverse neurological symptoms and prevent irreversible alterations thus emphasizing the need to recognize early clinical manifestations [1,2,5,6].…”

Fahr's syndrome is a rare, degenerative, and neuropsychiatric disorder characterized by seizures, extrapyramidal, and neuropsychiatric symptoms as a result of symmetric and bilateral calcifications of the nucleus pallidus, the putamen, the dentate nucleus of the cerebellum, and the hemispheric white matter at the base of the skull. The female patients, who has 53-year-old, was admitted in the intensive care unit with status epilepticus for 24 hours associated to acute respiratory failure due to aspiration pneumonia. She had undergone a thyroidectomy 22 years ago, when she started involuntary lasting muscular contractions of the upper extremities, which progressed to convulsions throughout the years. There were Chvostek and Trousseau signs. Laboratory tests showed ionic calcium of 0.55 mmol/L. Computed tomography scan of the brain showed intracranial symmetrical calcifications of the basal nuclei, semioval center, occipital, and cerebellar cortex. According to the clinical presentation, examination findings, and subsequent investigation exams, our case was diagnosed as Fahr's syndrome due to post-thyroidectomy hypoparathyroidism. Fahr's syndrome should be considered in patients with neuropsychiatric disturbances and seizure disorder, especially following thyroidectomy.
