Abstract

Uveitis Meningoencephalitis Vogt-Koyanagi-Harada disease Magnetic resonance imaging

A 40-year-old Japanese woman, formerly diagnosed as having Vogt-Koya­ nagi-Harada disease (VKH). developed a consciousness disturbance. There were nuchal rigidity and mild right facial weakness. Ophthalmological find­ ings were compatible with VKH. Lumbar puncture revealed moderate pleocy­ tosis. MRI showed multiple focal lesions. This case verifies parenchymatous involvement of CNS in VKH.

Vogt-Koyanagi-Harada disease (VKH) is a rare disor­ der of unknown origin [1. 2]. Its manifestations include uveitis and meningitis. Integumentary involvement, such as vitiligo, poliosis and alopecia, is also common [2, 3]. It is well documented mainly in the Japanese literature and to a lesser degree in other countries. Its neurological mani­ festations arc poorly understood, and its pathophysiologyleaves much to be elucidated. We present a case of VKH showing meningoencephalitis and discuss the clinicopathological correlation.

Case Report A 40-year-old Japanese woman was admitted because of con­ sciousness disturbance. She was healthy until 10 years before admis­ sion. when she developed bilateral impairment of visual acuity. A diagnosis of VKH was established. Cerebrospinal fluid was reported to have shown pleocytosis. She recovered spontaneously and subse­ quently remained well. Two weeks before admission, she noted gen­

eral fatigue and fever. One week later, she became disoriented and confused and was brought to our hospital. Her temperature was 39.2 "C, pulse 120 per minute and blood pressure 140/80 mm Hg. There was no lymphadenopathy, vitiligo, poliosis alopecia, erythema nodosum or thrombophlebitis. Genitalia were normal. On neurologic examination, she responded only to nox­ ious stimuli. The neck was stiff. The cranial nerves were normal except for mild right supranuclear facial weakness. There seemed to be no other overt motor dysfunction. Ophthalmologic examination revealed depigmentation of the chorioidea and a few Dalen-Fuchs’ spots, compatible with VKH. There was no physical finding suggest­ ing Behyet’s disease, tuberculosis, or toxoplasmosis. The white cell count was 22,800 (neutrophils 79%). A lumbar puncture, under an initial pressure of 200 mm H?0, revealed a pleo­ cytosis of 297/mm3 (28% monocytes and 72% polymorphonuclear cells), 65 mg/dl glucose and 61 mg/dl protein. CSF and blood cul­ tures were negative. The following laboratory tests were all normal: FTA-ABS, PPD skin test, antinuclear antibodies, latex agglutination test for toxoplasma and skin puncture test. An electroencephalogram showed prominent diffuse delta activity. Auditory brainstem re­ sponse and short latency somatosensory evoked potential were nor­ mal. Head CT scan revealed a low density lesion in the anterior limb of the left internal capsule with no contrast enhancement (fig. 1). Mag­ netic resonance was performed with a 0.5-tesla superconduction

Introduction

Fig. 2. Axial Ti-wcightcd (2.000/I00) MRI. Abnormal increased signal intensity in the region of the head of the left caudate nucleus, the anterior limb of the left internal capsule, the left putamen, the left temporoparieto-occipital region and the convex of the left cerebral hemisphere (a). High intensity is also noted in the tegmentum and the cerebellum (b).

magnet (Toshiba, Japan). Images were produced by a spin echo (SE) technique. A multislice multiecho technique was utilized to obtain axial images with an echo delay time (TE) of 30 and 100 ms and a repetition time (TR) of 2.000 ms. On the Ti-wcighted or proton den­ sity axial images, focal lesions of increased signal intensity were noted in the region of the anterior limb of the left internal capsule, the left temporoparieto-occipital region, the convex of the left hemi­ sphere. the tegmentum and the cerebellum (fig. 2). Bilateral carotid and vertebral angiography was negative. The patient had HL.A-tvpes A2, A24. Bw54, Bw55. Cwl and DR4. Only with general supportive care did her clinical condition steadily improve. We did not give her steroids. Follow-up lumbar puncture also revealed a decrease in CSF pleocytosis to 17/mm3 finally. During the course of recovery, it was difficult to evaluate the neuropsychological state because of associated consciousness distur­ bance. She became afebrile, alert and free of neurological deficit. She was discharged on the 30th hospital day. Convalescent serum showed no significant increase in the titers of viral antibodies, including herpes simplex, herpes zoster, mumps, measles, echo, coxsackie- and Japanese encephalitis virus. MRI, done 2 months after the acute episode, when she lived a healthy life, still revealed abnor­ mal intensity in the left caudate nucleus.

Discussion

This is a case of VKIT with meningoencephalitis. The uveomeningoencephalitic syndrome is caused by miscel­ laneous disorders [4], In this case, typical ophthalmo­ scopic findings, including Dalen-Fuchs’ spots and pleocy­

tosis in CSF, support the diagnosis of VKF1 [4], Labora­ tory data suggest no other disease such as Behcet's dis­ ease, toxoplasmosis or tuberculosis. Moreover, HLA typ­ ing is also compatible with VKH [5]. The patient presented with febrile illness and devel­ oped consciousness disturbance. Radiological examina­ tion verified the involvement of CNS compatible with meningoencephalitis. Many of the neurological features of VKH, such as hemiparesis. conjugate deviation of the eyes, ataxia and spinal cord signs, suggest not only menin­ geal but also parenchymatous involvement [6-11], How­ ever, there are only a few reports describing the radiologi­ cal findings of the brain in VKH. Lubin et al. [9] and Hiraki et al. [10] described cases with various neurologi­ cal signs, but CT were normal in all cases. To our knowl­ edge, MRI in this disorder have been evaluated in only 1 case. Nitta and Takamori [11] reported a case of VKH with Wallenberg's syndrome. MRI revealed high intensity area mainly in the cerebellum. Vertebral angiography dis­ closed occlusion of the right posterior inferior cerebellar artery1. They postulated vasculitis and/or demyelination in the central nervous system in VKH. In our case, CT revealed a low density lesion only in the anterior limb of the left internal capsule, but MRI disclosed more wide­ spread lesions extending from the cerebral cortex and white matter to the brainstem. In contrast with their case.

the distribution of'the lesion is not compatible with vascu­ lar origin in our case. Moreover, angiography was nega­ tive. Therefore, infarction is not likely. The variety of the location of the lesions appears like that of such myelin disorders as multiple sclerosis. However, the abnormal signal intensities on MRI involve not only the white but also the gray matter. The pathological character of the lesions is difficult to specify, but several findings suggest an encephalitis-like process. The clinical picture including consciousness dis­ turbance, EEG slowing, pleocytosis in CSF and the self­

limited course in this case is similar to that of benign viral encephalitis. Ocular pathology in VKH consists of an inflammatory process with or without granuloma [2, 12], Very few reports are available concerning the pathology of the central nervous system. Some equivocal cases involve an inflammatory process [1], We conclude that parenchymatous involvement of the CNS in VKH may not be rare, and careful neurological evaluation should be performed in all cases of VKH. MRI is the preferable imaging technique for the detection of the lesion.
