A 36-year old male with a three year history of HIV infection and more recently, CMV retinitis, had several episodes of polyradiculitis with severe bilateral leg pain and urinary retention which resolved slowly over several months. He then presented with high fevers and severe dysphagia with dehydration. Examination showed oral thrush, dyarthric speech and mild memory impairment. Fundoscopic exam showed CMV retinitis and HIV retinopathy. Further examination revealed other cranial nerve signs and leg weakness. MRI scans showed several contrast enhancing abnormalities of cranial nerve roots. The patient died from massive barium aspiration. At autopsy the brain showed multiple CMV cranial neuritis, CMV polyradiculitis and CMV ventriculo-ependymitis. While spinal nerve root involvement by CMV may occur in up to 1% of AIDS patients, involvement of cranial nerves is unusual and CMV infection of multiple cranial nerves is distinctly rare.

Leptomeningeal carcinomatosis (LMC) is a diffuse or multifocal malignant infiltration of the pia matter and arachnoid membrane. The most commonly reported cancers associated with LMC are breast, lung, and hematological malignancies. Patients with LMC commonly present with multifocal neurological symptoms. We report a case of LMC secondary to gastroesopha-geal junction cancer present initially with cauda equina syndrome. A 51-year-old male patient with treated adenocarcinoma of the gastroesophageal junction presented with left leg pain, mild weakness, and saddle area numbness. Initial radiological examinations were unremarkable. Subsequently, he had worsening of his leg weakness, fecal incontinence, and urine retention. Two days later, he developed rapidly progressive cranial neuropathies including facial diplegia, sensorineural hearing loss, dysarthria, and dysphagia. MRI with and without contrast showed diffuse enhancement of leptomeninges surrounding the brain, spinal cord, and cauda equina extending to the nerve roots. Cerebrospinal fluid cytology was positive for malignant cells. The patient died within 10 days from the second presentation. In cancer patients with cauda equina syndrome and absence of structural lesion on imaging, LMC should be considered. To our knowledge, this is the first case of LMC secondary to gastroesophageal cancer presenting with cauda equina syndrome.
