| Popis: | Epileptic seizures are defined as the transient appearance of signs or symptoms due to excessive or synchronous neuronal activity in the cerebral cortex. Pheochromocytomas and paragangliomas (PPGL) are tumors of chromaffin cells that arise from the medulla of the adrenal gland in 80-85% of patients and from the extra-adrenal sympathetic tissue of the abdomen, pelvis and chest in 10-20% of patients. The clinical picture of PPGL is variable and ranges from the absence of symptoms to severe clinical picture, depending on the biochemical profile. They are most often manifested by paroxysmal hypertension, followed by episodes of severe headache or diaphoresis, while epileptic attacks are rare. Neurological symptoms are present in many patients with PPGL. Also, paroxysmal neurological conditions such as vasodilating headache, intracranial tumors, diencephalic-autonomic epilepsy, hypertensive encephalopathy, focal arterial disease of the brain and anxiety state have been described, which may have similar clinical manifestations with pheochromocytomas. We present a 44-year-old woman, who has been diagnosed with pheochromocytoma as possible etiological basis of epileptic seizures. Pheochromocytoma, with its low incidence and "chameleon" clinical spectrum, should be considered as a potential etiological factor of convulsions. |
