Glycogen storage diseases (GSD) are inherited metabolic disorders of glycogen metabolism. Different hormones, including insulin, glucagon, and cortisol regulate the relationship of glycolysis, gluconeogenesis and glycogen synthesis. The overall GSD incidence is estimated 1 case per 20000-43000 live births. There are over 12 types and they are classified based on the enzyme deficiency and the affected tissue. Disorders of glycogen degradation may affect primarily the liver, the muscle, or both. Type Ia involves the liver, kidney and intestine (and Ib also leukocytes), and the clinical manifestations are hepatomegaly, failure to thrive, hypoglycemia, hyperlactatemia, hyperuricemia and hyperlipidemia. Type IIIa involves both the liver and muscle, and IIIb solely the liver. The liver symptoms generally improve with age. Type IV usually presents in the first year of life, with hepatomegaly and growth retardation. The disease in general is progressive to cirrhosis. Type VI and IX are a heterogeneous group of diseases caused by a deficiency of the liver phosphorylase and phosphorylase kinase system. There is no hyperuricemia or hyperlactatemia. Type XI is characterized by hepatic glycogenosis and renal Fanconi syndrome. Type II is a prototype of inborn lysosomal storage diseases and involves many organs but primarily the muscle. Types V and VII involve only the muscle.

BACKGROUND Basal ganglia calcification (BGC) is a rare sporadic or hereditary central nervous system (CNS) abnormality, characterized by symmetric or asymmetric calcification of the basal ganglia. CASE REPORT We report the case of a 65-year-old Gypsy female who was admitted for a tetanic seizure, and who had a history of polyneuropathy, restless-leg syndrome, retinopathy, diabetes, hyperlipidemia, osteoporosis with consecutive hyperkyphosis, cervicalgia, lumbalgia, struma nodosa requiring thyroidectomy and consecutive hypothyroidism, adipositas, resection of a vocal chord polyp, arterial hypertension, coronary heart disease, atheromatosis of the aorta, peripheral artery disease, chronic obstructive pulmonary disease, steatosis hepatis, mild renal insufficiency, long-term hypocalcemia, hyperphosphatemia, impingement syndrome, spondylarthrosis of the lumbar spine, and hysterectomy. History and clinical presentation suggested a mitochondrial defect which also manifested as hypoparathyroidism or Fanconi syndrome resulting in BGC. After substitution of calcium, no further tetanic seizures occurred. CONCLUSIONS Patients with BGC should be investigated for a mitochondrial disorder. A mitochondrial disorder may also manifest as tetanic seizure.
