Abstract
Neurological findings and histopathology of the nervous system were studied in 30 patients with Kawasaki disease. As neurological manifestations, irritability, lethargy, meningeal signs such as nuchal rigidity, Kernig's sign, and opisthotonus, and facial nerve paralysis were present in 8 patients. In 9 out of 11 patients who had examination of cerebrospinal fluid, pleocytosis mainly consisting of lymphocytes and mononuclear cells was seen. Protein and glucose concentrations were within normal range. On histopathological investigation, aseptic chorio and/or leptomeningitis were present in 7 out of 14 patients. Severe edema, edema necrosis and localized status spongiosus were frequently observed. Atrophy, nonspecific degeneration and loss of neurons were detected, but pathognomonic changes were not evident. Marginal gliosis in the subpendimal region and superficial cerebral cortex and glial nodule formation surrounding the degenerated neurons were occasionally seen. Vascular changes such as endoarteritis, periarteritis and perivascular cuffing were present in 5 out 14 patients, though such lesions were geneally mild. Ganglionitis and neuritis in the various areas were seen in 13 patients.
