The authors describe a case in which 0.5 cc of 5% fluorescein diluted in 10 cc of cerebrospinal fluid (CSF) was injected at the L4-5 level for evaluation of nasal CSF leakage. Within minutes, tone increased in lower extremities accompanied by knee and ankle clonus and subjective numbness up to the waist. Non-preserved saline irrigation of the lumbar CSF was administered until it became clear, and the patient's head was elevated to retard the developing symptomatology. Although a transient temperature elevation was observed with negative CSF cultures, all signs and symptoms cleared within 48 hours. In a survey of the members of the Americal Association of Neurological Surgeons regarding frequency of use and complications stemming from intrathecal fluorescein, the response rate was 58.3% (1111) of the 1907 members, of which 6.8% (76) had used intrathecal fluorescein, and among those, 25% (19 of the 76) had observed complications involving lower extremity weakness, numbness, generalized seizure activity, opisthotonos, and cranial nerve deficit. No complications were permanent. The authors recommend caution if intrathecal fluorescein must be used. Means should be available to clear the CSF of the agent and elevate the head if complications arise.

A newborn male developed diffuse myoclonus. Right frontal craniotomy revealed a thin hemispheric mantle and a cyst communicating with the right lateral ventricle. In the biopsy of the cyst wall there were the characteristic findings of malakoplakia, granulomatous inflammation with von Hansemann histiocytes and Michaelis-Gutmann bodies. The child died at 1 1/2 years of age.

A limited access to the middle cranial fossa can be achieved by an opening created in the posterior portion of the lateral orbital wall. An intracranial foreign body was removed by this method.
