Hypokalemic periodic paralysis one of the channelopathy disorders with low serum potassium level, clinically presenting as acute onset extremity weakness. In most cases, the cause of the hypokalemia is familial, but rarely hypokalemic periodic paralysis occurs secondary to other diseases including endocrinopathies, renal disorders, gastrointestinal loss. We report a patient with no known underlying diseases, who were diagnosed with sporadic hypokalemic periodic paralysis accompanied by neurogenic diabetes insipidus.

Contrast-induced encephalopathy (CIE) is a rare complication of angiography and endovascular intervention following administration of iodinated intravenous contrast agents. Neuroimaging findings of CIE usually show cerebral edema, leptomeningeal enhancement, and parenchymal signal abnormality on fluid-attenuated inverse recovery (FLAIR). Hyperintense acute reperfusion marker (HARM) generally implies an enhancement of the subarachnoid cerebrospinal fluid space on brain FLAIR imaging in cases of acute ischemic stroke or hyperperfusion syndrome. We report a case of possible CIE following cerebral angiography, accompanied by HARM sign.
