Movement disorders following midbrain haemorrhage are infrequently encountered in rehabilitation, and are uncommonly corrected by pharmacologic means. This report describes a 20 year-old male with a prior history of cocaine abuse who presented with a 4 day history of dysarthria and blurred vision following methamphetamine abuse. Physical examination demonstrated hypertension, left facial hemispasm, bilateral upward gaze paresis and ataxic gait. Magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) showed multifocal parenchymal haematomas in the mesencephalic tegmentum, subcortical left front region and right anterior thalamus consistent with cavernous angiomas. The patient was transferred to rehabilitation on hospital day 5. The following day, he developed choreoathetoid movements, dystonia, and aphasia, secondary to an extension of the midbrain haemorrhage. Cogentin was initiated with slight improvement in choreoathetoid movements. The patient began intensive multidisciplinary rehabilitation therapy but after 18 days of therapy, the patient remained totally dependent in activities of daily living (ADLs), transfers, mobility and was unable to communicate in any manner. A trial of Sinemet was initiated, with resultant steady improvement in functional ability over the next month. By discharge, the patient was independent in ADLs and ambulation. By 9 months post discharge follow-up, the patient was fully independent with normal cognition, and had self tapered all medications without ill effect. Dopamine agonist trials of appropriate duration appear indicated in cases of movement disorder (paucity or excess) following midbrain lesions.

An 85-year-old female presented with a 3-month history of worsening hyperlacrimation and blurred vision following blunt head injury. Her past medical history was unremarkable. Her blood examination identified no abnormal findings. Neuroophthalmological inspection revealed extraocular movement disorder and mild exophthalmos on the affected side. Her visual acuity was not disturbed. Neuroimaging showed a cystic mass located extraconally in the superolateral compartment of the anterior orbit, without enhancement by contrast medium. Surgical exploration resulted in escape of chocolate-colored, liquefied hematoma during dissection. No vascular lesion was found. A grayish-white cyst wall was found adhering strongly to the lateral and superior rectus muscles. The lacrimal gland was not identified. The mass was totally resected. Histological examination indicated dermoid cyst with inflammatory interstitial hemorrhage. No component of vascular malformation or atypia was found. Hyperlacrimation and extraocular movement improved postoperatively. We thought that the previous blunt head injury might have induced intratumoral hemorrhage in the preexisting dermoid cyst and that the escaped contents caused inflammatory irritation, resulting in the hyperlacrimation. Dermoid cyst may show atypical presentation with intratumoral hemorrhage and should always be included in the differential diagnosis of orbital tumor.

A woman in her early 60s presented to our Movement Disorders Centre with a 5-year history of progressive peripheral neuropathy, gait instability with falls, blurred vision, cognitive impairment and tremors. The patient was found to have profound sensory ataxia, chronic ophthalmoplegia, dementia with significant deficits in registration and construction and bilateral resting tremor of the hands. Investigations revealed an unremarkable MRI of the brain, negative cerebrospinal fluid studies, and unremarkable chemistries. Nerve conduction studies found a severe sensorimotor axonal polyneuropathy. Genetic testing revealed a compound heterozygous mutation in the POLG1 gene consistent with the diagnosis of Sensory Ataxia Neuropathy Dysarthria and Ophthalmoplegia (SANDO) syndrome.
