A 16-year-old boy with Fabry's disease had sudden onset of diplopia unassociated with any other neurologic symptoms. A right internuclear ophthalmoplegia characterized by optokinetic phenomena and ocular dysmetria was demonstrated. The diplopia resolved spontaneously in six weeks. This is the first reported case of internuclear ophthalmoplegia occurring with Fabry's disease and represents one of the youngest patients to have unilateral internuclear ophthalmoplegia presumably caused by vascular occlusive disease.

Fabry's disease (FD) is a rare, sex-linked disorder resulting from alpha-galactosidase deficiency. Cerebrovascular complications have been reported in the literature but have not been systematically analyzed. We report 2 patients and review 51 previously reported cases (descriptive meta-analysis) to clarify the clinical, radiologic, and pathologic features. The average age at onset of cerebrovascular symptoms was 33.8 years for hemizygous individuals (n = 43) and 40.3 years of heterozygotes (n = 10). The most frequent symptoms and signs were as follows (in descending order of frequency): hemiparesis, vertigo/dizziness, diplopia, dysarthria, nystagmus, nausea/vomiting, head pain, hemiataxia, and ataxia of gait, in the hemizygote group; and memory loss, dizziness, ataxia, hemiparesis, loss of consciousness and hemisensory symptoms, in the heterozygote group. The vertebrobasilar circulation was symptomatic in 67% of the hemizygotes and 60% of the heterozygotes. Intracerebral hemorrhage was found in 4 patients (3 hemizygotes and 1 heterozygote). Elongated, ectatic, tortuous vertebral and basilar arteries were the most common angiographic and pathologic features. For the hemizygotes, the recurrence rate for cerebrovascular disease was 76% and the death rate was 55%; 86% of the heterozygotes had recurrent cerebrovascular event(s) and 40% died. The cerebrovascular manifestations of FD, in both hemizygotes and heterozygotes, are predominantly due to dilative arteriopathy of the vertebrobasilar circulation, frequently recur, and portend a poor prognosis.

We describe four patients with cerebrovascular complications from two unrelated Italian families with Anderson-Fabry disease. Clinical examination, neuroimaging (MRI), biochemical and genetic analyses were carried out in all the patients. Alpha-galactosidase A activity was detected by fluorimetric assay and genetic analysis was performed by DNA sequencing. Family 1. A male patient presented recurrent strokes when he was 34 years old, albuminuria and subsequently progressive renal failure to renal transplantation. Family 2. A male patient, aged 32 years, had diplopia for a few days and then recurrent strokes with left spastic hemiparesis and internuclear ophthalmoplegia. A female patient, aged 48 years, presented L-dopa-responsive parkinsonism, and her sister had stroke when she was 55 years old. MRI was abnormal in all the patients and showed lacunar infarctions in the periventricular white matter, basal ganglia and pons. Lesions were detected by MRI even before stroke in a female patients. In patients with Anderson-Fabry disease, stroke is a frequent complication, and may be the first threatening clinical manifestation. In young people with undefined stroke, even without signs of renal involvement, it is important to consider the diagnosis of Anderson-Fabry disease and so to perform clinical examination and biochemical analyses. The pre-clinical stage of cerebrovascular involvement may be evaluable by MRI.

Fabry disease (FD) is an X-linked inborn error of metabolism resulting from the deficient activity of alpha-galactosidase A which leads to the widespread deposition of glycosphingolipids in lysosomes, and to ischemic complications involving kidneys, heart and brain. Among neurological symptoms, strokes and transient ischemic attacks (TIA) have been reported. A 30-year-old male patient, with FD, was referred to us for evaluation of a sudden episode of dizziness, with disequilibrium, and diplopia, in agreement with the diagnosis of a TIA. Head magnetic resonance imaging (MRI) showed no cerebrovascular involvement but revealed the presence of Chiari type I malformation (CMI). We subsequently performed head MRI in a cohort of 44 consecutive hemizygous male patients and seven heterozygous females affected with FD, and identified three additional cases (two males and one female) of CMI. Whether the association is coincidental or not will need further studies but our data suggest that CMI should be ruled out in all Fabry patients.

We present the case of a 36-year-old woman affected with Fabry disease (FD), with neuroradiologic and laboratory tests suggestive of a coexistent inflammatory demyelinating disease. Since the age of 23, she presented recurrent neurologic deficits, such as right limb paresthesias, diplopia, and right leg weakness. Magnetic resonance imaging revealed multiple demyelinating lesions in periventricular areas, corpus callosum, and spinal cord. Cerebrospinal fluid analysis showed the presence of oligoclonal bands, while visual-evoked potentials were delayed with preserved morphology. FD is usually considered as a differential diagnosis of multiple sclerosis, but we think that the best explanation of all pathological features in this case is the coexistence of the two diseases.
