Abstract

A new and rapid vital-stain method for the diagnosis of CSF cells demonstrates not only red blood cells but also white blood cell types, predominantly by differentiating nuclear patterns. 20 microliter untreated CSF are put on the prestained slides and a cover slip put over it. Differentiation can be made after 15 minutes. The lower limit is at 3-4 WBC/ml of CSF. At room temperature the preparation keeps for about an hour. The method is reproducible and has the advantage also over other routine methods that the CSF volume is very small and there is neither loss of cells nor cell denaturation.

Cerebrospinal fluid dissecting into spinal epidural space after lumbar puncture causing cauda equina syndrome: review of literature and illustrative case.

OBJECTS: We report a case of epidural cerebrospinal fluid (CSF) leak after lumbar puncture caused by CSF dissecting into the spinal epidural space. The incidence of this phenomenon may be higher than suspected, although most cases may remain asymptomatic. MATERIALS AND METHODS: A 4-year-old girl with new-onset seizure underwent a diagnostic lumbar puncture, the results of which were normal; 3 h later, she began experiencing severe low-pressure headaches and lower back pain, bilateral lower extremity weakness, numbness, and pain, and urinary retention when upright. Spinal MRI demonstrated extensive epidural CSF collection posterior to the thecal sac extending from the cervicothoracic junction to the sacrum. After 48 h in the supine position and gradual mobilization, the patient had complete resolution of symptoms and no neurological sequelae. CONCLUSION: Patients usually recover without any neurological deficits after conservative treatment. Prone or lateral decubitus positioning immediately after lumbar puncture may decrease the incidence of this phenomenon.
