A retrospective review of charts for 650 children who had lumbar puncture for suspected meningitis was undertaken to determine the characteristics of patients with and without meningitis, identify other conditions suggesting meningitis, and evaluate the predictive value of signs and symptoms of meningitis. The incidence of positive lumbar punctures increased with patient age. Younger infants did not present with classical features of meningitis. Bulging fontanel, lethargy, and irritability were nonspecific symptoms. Vomiting and headache, although not specific, proved to be more sensitive indicators of meningeal infection. Most patients with meningitis (75%) had at least one sign of meningeal irritation, but so did 25% of patients without meningitis. Brudzinski's sign was not specific. In contrast, nuchal rigidity and Kernig's sign had high predictive value. Up to age five, the diseases most often suggesting meningitis were right-sided pneumonia, gastroenteritis, otitis, tonsillitis, exanthema subitum, and urinary tract infections. Of 171 patients with febrile convulsion, one (0.5%) had bacterial meningitis and four had aseptic meningitis.

Cerebrospinal fluid (CSF) involvement in myeloma is rarely seen. Recently we experienced a case with this lesion. A 70-year-old man developed consciousness level disorder during the course of bronchopneumonia. Neurological examination revealed stuporous consciousness, neck stiffness and Kernig's sign. Immunoelectrophoresis showed monoclonal IgG in serum. CSF which was obtained through lumbar puncture was clear and its pressure was 155 mm H2O. It contained 207 white cells/3 mm3; glucose, 54 mg/dl; and protein, 33 mg/dl. The differential count of the CSF was (in %) monocytes, 48.0; plasma cells, 25.5; neutrocytes, 15.5; and lymphocytes, 11.0. Cytoplasm and nucleus of the plasma cells were in various sizes. Some irregular multiple nuclei, flaming cells and grape cells were also observed in them. The cytoplasm of the plasma cells fluoresced with antisera against lambda chains IgG. The value of immunofluorescent technique in identifying plasma cells in the CSF is emphasized.

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.

Rathke's cleft cysts are sometimes associated with aseptic meningitis or metabolic encephalopathy due to hyponatremia. We treated such a case manifest by lethargy, fever and electroencephalographic abnormalities. A 68-year-old man was admitted to our ward after experiencing general malaise, nausea and vomiting and then high fever and lethargy. On admission, he was drowsy and had nuchal rigidity and Kernig's sign. Physically, he was pale with dry, thickened skin. He had lost 5.0 kg of body weight in the last month. His serum sodium was 115 mEq/l. He had a low serum osmotic pressure (235 mOsmol/l) and a high urine osmotic pressure (520 mOsmol/l). His urine volume was 1200-1900 ml/24 h with a specific gravity of 1008-1015. The urine sodium was 210 mEq/l. He did not have an elevated level of antidiuretic hormone. Electroencephalograms showed periodic delta waves over a background of theta waves. With sodium replacement, the patient become alert and symptom free, and his electroencephalographic findings normalized. However, the serum sodium level did not stabilize, sometimes falling with a recurrence of symptoms. Magnetic resonance imaging clearly delineated a dumbbell-shaped intrasellar and suprasellar cyst. The suprasellar component subsequently shrunk spontaneously and finally disappeared. An endocrinologic evaluation showed panhypopituitarism. The patient was given glucocorticoid and thyroxine replacement therapy, which stabilized his serum sodium level and permanently relieved his symptoms. A transsphenoidal approach was performed. A greenish cyst was punctured, and a yellow fluid was aspirated. The cyst proved to be simple or cubic stratified epithelium, and a diagnosis of Rathke's cleft cyst was made. The patient was discharged in good condition with a continuation of hormonal therapy. Rathke's cleft cyst can cause aseptic meningitis if the cyst ruptures and its contents spill into the subarachnoid space. Metabolic encephalopathy induced by hyponatremia due to salt wasting also can occur if the lesion injures the hypothalamus and pituitary gland.
