Presented here is an unusual case of a 41-year-old man with idiopathic hypoparathyroidism strongly connected with dermatological, ophthalmological and neurological disorders. Since the age of 4 he had been treated ineffectively for mycosis resulting in complete baldness and atrophic nail plate changes. At the age of 35 he was diagnosed with idiopathic hypoparathyroidism. He underwent surgery twice due to bilateral cataract. CT scans of the head demonstrated numerous symmetrically located calcifications in both frontal lobes, subcortical nuclei, the paraventricular region, brain fornix, and both cerebellar hemispheres. The neuropsychological examination demonstrated the occurrence of psychosensory disorders under the form of hallucinations accompanied by a sense of fear and anxiety. It seems essential to investigate the parathyroid gland for any sign of pathology, especially amongst patients with servere dermatological and/or neuropsychological symptoms. Early diagnosis and treatment of patients with hypoparathyroidism may prevent the development of many serious complications or at least result in marked improvement of neurological manifestations.
