Background:Progressive multifocal leukencephalopathy (PML) is a rare, sometimes fatal viral disease in patients with primary or secondary immunosuppression.
Case Description:A 57-year-old immunocompetent female with intractable Holmes tremor and elongated unique brainstem lesion reported to our hospital. The cerebrospinal fluid (CSF) screening for John Cunningham virus was negative and the diagnosis was established by brain biopsy. The course was rapidly fatal.
Conclusion:This atypical presentation of PML in an immunocompetent patient illustrates that diagnosis can be missed without brain biopsy.
Keywords: Brainstem, Holmes tremor, immunocompetence, JC virus, progressive multifocal leukencephalopathy
Progressive multifocal leukoencephalopathy (PML) is caused by the JC virus, a polymavirus discovered in 1971 and named using the initials of a patient with PML.[
We report about a female patient with PML, but without any known immunodeficiency. The fulminate clinical course was dominated by intractable Holmes tremor and fatal outcome.
A 57-year-old female had been evaluated in two other departments 4 months before admission to our hospital. She initially complained of weakness of the right hand and weakness in both legs. At the initial examination, she presented a palsy of the left abducens nerve as well as dysarthria and right-sided hemiparesis with dysmetria, ataxia, and loss of epicritic sensibility. She demonstrated intermittent tremor of unknown etiology of the right thumb and index. There was mild and reproducible lymphopenia of 0.860 G/L (normal values: 1.500-4.000 G/L), but the hematological work-up was normal. Human immunodeficiency virus (HIV) serology was negative. PCR screening in the CSF for Herpes simplex virus, tropherymawhippelii, and PML was negative. The initial MRI (Flair and T2-weighted sequences) showed a hyperintense lesion extending from the postero-lateral left portion of mesencephalon. Most characteristic sequences are shown in
MRI on admission (5 months before death). MRI on admission (a and b) transversal and sagittal Flair sequence; (c) Sagittal T2-weighted sequence. Demonstration of a hyperintense lesion extending on both side of the pons (arrow), predominantly on the left side beneath the red nuclei up to the right sided mesencephalon along the third ventricle
The patient received a 3-day-trial of high dosage steroids, without any benefit. Brain biopsy was considered too risky to be performed. This decision was reversed 4 months later, as there was further rapid deterioration. Therefore, the patient was admitted to our neurosurgical department. She had noted further progressive weakness and, in particular, constant “shaking” of the right hand. She complained of intractable pain in the right leg and constant diplopia. The neurological examination demonstrated divergent strabismus due to possible left-sided paresis of 3rd and 6th cranial nerve. At the paretic right arm, there was constant, spontaneous, rapid, mostly arrhythmic tremor both at rest and when the patient tried to move the extremity. Tremor abatement was only observed during sleep.
Mild lymphocytopenia was confirmed. Electroencephalography did not reveal focal epileptic discharges. MRI of the brain revealed further local brainstem extension; as for the initial MRI there was no detectable cortical lesion. After informed consent stereotactic brain biopsy of the left brainstem was performed. The tremor syndrome remained refractory to various therapeutic approaches. The patient died 6 months after the onset of the disease. The results of the histological examination (see below) were not yet known at the time of death. The biopsy specimen [
The present case with PML involving the brainstem and fatal outcome within 6 months is remarkable for several reasons. The patient had no overt signs of immunodeficiency. Only a few cases have been reported in immunocompetent patients.[
Screening for the JC antigen by PCR technique in the CSF had been negative 9 weeks before the positive brain biopsy. Due to the brainstem extension, no further CSF analysis was performed. Remarkably only a few PML cases have been reported where JCV was undetectable in the CSF, but detected by brain biopsy.[
The complex tremor best fits descriptively with Holmes tremor, and it was refractory to any treatment. This tremor was high-amplitude, but low frequency while extending to the arm. It was also present at rest and with intention, evoking this phenomenological classification.[
The fulminant course with rapidly fatal outcome is not unusual. We cannot exclude that steroids given twice may have hastened the course first, by initiating the immune reconstitution inflammatory syndrome (IRIS), second by slowing IRIS at an inappropriate time.[
This case report highlights several points. Immunocompetent persons may develop PML; diagnosis may be missed by CSF screening for JCV; localization can be exclusively in the brainstem, Holmes tremor can be the predominant clinical syndrome.
