The authors describe side effects of Dimer X radiculography after premedication. The side effects in a study of hundred patients are divided in early complications (during the examination : dizziness, radicular pains and collapse) and in late complications (noted during the first day following the examination : headache, meningismus, myocloni, epileptic seizure, cauda syndrome, increase of radicular pains). After premedication with tiapride the rate of dizziness is decreased, the rate of headache is not diminished, but the headaches are very slight. Nausea and vomiting are suppressed by the premedication.

The adverse side effects in a series of 439 myelographies with metrizamide were analyzed. The most frequent side effect was headache, which could be differentiated as early onset headache, related to hydrodynamic modifications in the spinal fluid following lumbar puncture, and late onset headache related to a metrizamide effect. The frequency of late onset headache was at least 27%, but all together 46% of the patients had postmyelographic headache. Meningeal irritation was seen in 5%, sometimes in a severe form, mimicking a septic complication. Spinal irritation and epileptic fits were rarely seen. Striking was the occurrence of an acute psycho-organic syndrome, frequently observed after cervical myelography which was performed with a higher than usual dose of iodine. We can not confirm the general opinion that the central nervous system had a good tolerance for metrizamide.

Pathologic examination in a case of fatal intracerebral hemorrhage from a berry aneurysm showed that the "sentinel" or warning headache in this patient was due to the leakage of blood into the subarachnoid space through a previous small tear in the wall of her saccular aneurysm. Oribital pain, transient, dysphasia, dizziness and, later, meningismus might have prompted the performing of a lumbar puncture to determine the presence of blood in the cerebrospinal fluid. This type of event is the likely pathogenetic mechanism for the premonitory headache that may precede a lethal rupture of a saccular aneurysm.

Pituitary Apoplexy is a rare but sometimes life threatening condition which requires prompt recognition and timely medical intervention to avoid catastrophic consequences. From January 1979 to June 1989 and total of one hundred and ninety eight pituitary tumor patients were operated on our hospital. Eighteen cases (9.1%) were diagnosed "pituitary apoplexy" according to histopathological findings. The group consisted of twelve men and six women ranging in age from twenty two to sixty one years with a mean of forty. There were three cases of prolactin-secreting adenomas (16.7%), four growth-hormone secreting adenomas (22.2%), and eleven nonfunctional adenomas (61.1%) with an incidence of 6.1%, 8.3%, and 11.4% respectively (P > 0.05). Clinical manifestation occurred acutely in 66.7% and nonacutely in 33.3%. The patients presented with headaches (100%), visual impairment (83.3%), visual field defects (66%), disturbed consciousness (22%), fever and meningismus (11%). Radiological examinations able to demonstrate abnormalities included plain skull films (84%), computed tomography (84.6%), and angiography (93.8%). Various investigations of endocrine function pre and post operatively showed a deficient gonad axis (53%, 62.5%), adrenal axis (26.7%, 56.2%), and thyroid axis (20%, 43.8%). Sixteen cases received a transsphenoid operation and three cases underwent a transfrontal craniotomy. No case of mortality was reported. Postoperative radiotherapy was given to nine cases and nine cases were followed up on a regular basis. Therefore, our retrospective study suggests that pituitary apoplexy is not uncommon and has an acute clinical presentation. No particular tumor type was prone to occur. Various radiological examinations could define perisellar abnormalities. With a decreasing order of hormone deficiency, gonad, adrenal and thyroid axis were observed during the course of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of a dissecting aneurysm of the left posterior inferior cerebellar artery caused by giant cell angiitis is presented. A 22-year-old woman was admitted on August 30, 1990, with sudden onset of severe occipital headache and vomiting. Neurological examination on admission only showed severe meningismus. CT scan demonstrated subarachnoid hemorrhage and a small hematoma in the 4th ventricle. A left vertebral angiogram demonstrated that the left posterior inferior cerebellar artery was occluded at the lateral medullary segment. We diagnosed subarachnoid hemorrhage from a dissecting aneurysm. On the day following admission, the patient underwent a left suboccipital craniectomy. The posterior inferior cerebellar artery was enlarged for a distance of about 8 mm and there was typical purplish-red appearance in the dissecting aneurysm. This aneurysm was excised after trapping. The histological diagnosis was primary localized giant cell angiitis without systemic involvement. The etiology of the intracranial dissecting aneurysm is obscure, but this report suggests that cerebral angiitis can be considered as an important factor.

Cryptococcus neoformans is an important opportunist pathogen in human immunodeficiency virus (HIV) infection. Cryptococcal meningitis (CM) 3rd after primary HIV neuropathy an Toxoplasma gondii among infectious neurological diseases in AIDS patients. Extrapulmonary infection due to C. neoformans has occurred in up to 13% of patients. 86% of the Cryptococcus spp isolates in the US, Canada, and Japan are serotype A. Thousands of infection due to var neoformans have been reported in AIDS patients but only 3 cases of var gattii. Cryptococcal pneumonia meningitis appears in 63-84% of AIDS patients with symptoms of fever, headache, meningism, and photophobia. 17-37% of AIDS patients with Cm die during therapy, and only 18-30% live over 12 months. Treatment in patients without immunodeficiency deficit is with a combination of .3 mg/kg/day of amphotericin B and 150 mg/kg/day of flucytosine for 4 weeks. A dose of .5-.8 mg/kg/day amphotericin was most effective although renal toxicity occurred in 80% of patients. Fluconazole has been used since 1987: cerebrospinal fluid concentrations reached 60-80% in serum. Treatment in 8 of 14 patients receiving 400 mg/day fluconazole failed while it did not in 6 patients treated with .7 mg/kg/day of amphotericin for 7 days and flucytosine 100 mg/kg/day. 200 mg/bid itraconazole was given to 32 patients with cryptococcosis (24 CM cases and 26 AIDS victims) and 65% of CM patients improved clinically with negative cultures. The relapse of 2 of 106 patients taking 200 mg/day fluconazole and 13 of 77 patients taking 1 mg/kg/week amphotericin B occurred in maintenance therapy. CM was suppressed in 10 of 15 patients with 400 mg/kg itrazonazole. Prophylactic use of azole drugs in AIDS does not protect completely from CM although it reduced systemic fungal infections such as cryptococcosis.

In the immunocompromised patient, even mild forms of any combination of headache, meningismus, altered mental status, or focal neurologic signs should initiate an evaluation for possible CNS infection. The limited signs and symptoms of acute CNS infection are not due to specific organisms but to pathologic changes at the neuroanatomic site of infection. The initial clinical history, examination, laboratory, and neuroradiographic data will narrow the problem to one of several groups of agents, although it may not be possible to specify a single causative agent. It should be remembered that several concurrent infections (i.e., CMV and toxoplasmosis, aspergillosis, and bacterial sepsis) may be present. Thus, the clinician should rely on broad antibiotic coverage appropriate to the suspected causative agent or agents at the site of infection. It may be necessary to offer broad-spectrum antibiotic coverage for a CSF presentation that is subsequently found to result from a viral illness or from a noninfectious cause. However, one should avoid undertreating those infections for which specific therapy can be offered, and broad-spectrum treatment usually will not be regretted. Uncertainty in diagnosis following noninvasive procedures should lead to a brain biopsy. Although many of the infections discussed in this article have a poor prognosis, some of the most common pathogens, such as Cryptococcus, Listeria, and Toxoplasma, have effective specific therapies to which the patient should have access as rapidly as possible. The clinician who has successfully treated a patient with CNS infection should remain vigilant for late sequelae or recurrence of infection. Chronic treatment of some infections, such as toxoplasmosis or aspergillosis, may be necessary. The reintroduction of steroids for the treatment of an underlying cancer may reactivate previously treated disease, such as cryptococcosis, and periodic CSF surveillance is appropriate under these circumstances. Recurrence of the symptoms should raise the suspicion of recurrent or new infection, and the patient also should be evaluated with CT or MRI for the development of hydrocephalus or for new metastatic disease. In patients who have had varicella-zoster infection, postherpetic neuralgia and delayed arteritis may develop. Seizures, hearing loss, and neuropsychologic sequelae may follow any meningoencephalitis. The patient should always be reevaluated for the possibility of infection with a different opportunistic organism. CNS infections remain a major cause of morbidity and mortality in immunosuppressed patients with malignancies. In one series, 60% of such patients died as a result of their CNS infection, many at a time when the underlying disease had an otherwise good prognosis.(ABSTRACT TRUNCATED AT 400 WORDS)

Forty-eight cases of the Vogt-Koyanagi-Harada (VKH) syndrome occurring in patients residing in southern California were reviewed. Thirty-six patients were Hispanic and 12 of other racial groups. Symptoms of meningismus, predominantly headache, were present in 32 (67%) cases, but the other characteristic neurologic symptoms, i.e., tinnitus and dysacusis, were present in only eight (17%) and six (13%) cases, respectively. Dermatologic changes were rare; vitiligo occurred in five (10%) patients, alopecia in six (13%), and poliosis in three (6%). In this patient population, extraocular signs and symptoms of the VKH syndrome, other than headache, were unusual. The ocular manifestations of the VKH syndrome are more constant and include iridocyclitis, vitritis, diffuse swelling of the choroid, serous retinal detachment, and optic disc hyperemia. Procedures that may aid in the diagnosis include lumbar puncture, fluorescein angiography, and standardized echography. The ophthalmologist must be prepared to make this diagnosis and initiate treatment with high-dose systemic steroids based on the typical ocular findings even in the absence of other (extraocular) manifestations of this disease.

A 42-year-old man developed leptomeningeal carcinomatosis 6 years after treatment of a malignant melanoma. He was treated with two courses of recombinant interleukin-2, administered as a continuous intraventricular infusion (6 X 10E5 U/24 h) during 5 days. During the first day of the first course he also received 5 X 10E9 lymphokine-activated killer cells intraventricularly. This gave rise to a severe elevation of intracranial pressure, with headaches and meningismus. During the second course no LAK cells were administered. This course was tolerated much better. The neurological status did not change during the treatment. Recombinant interleukin-2 levels were maintained at about 300 U/mL during both courses.

A previously healthy 25-year-old woman suddenly developed right-sided facial numbness and a headache. The neurological examination was within normal limits with the exception of meningismus and right-sided facial sensory loss. A computed tomographic scan and a magnetic resonance imaging study demonstrated an acute hematoma in the right cerebellopontine angle. A 4-vessel cerebral angiogram revealed no abnormalities. Posterior fossa exploration disclosed a large, partially thrombosed, fusiform anterior inferior cerebellar artery aneurysm, which indented the pons at the trigeminal root entry zone. The aneurysm was excised, and the patient made an excellent recovery. She was left with a persistent trigeminal sensory deficit. Anterior inferior cerebellar artery aneurysms are rare lesions that generally present with a cerebellopontine angle syndrome; occasionally, facial sensory loss is also a feature. Isolated trigeminal sensory findings, as illustrated in this case, are extremely unusual in posterior fossa vascular lesions.
