The genome of the sparganosis tapeworm Spirometra erinaceieuropaei isolated from the biopsy of a migrating brain lesion.

Background: Sparganosis is an infection with a larval Diphyllobothriidea tapeworm. From a rare cerebral case presented at a clinic in the UK, DNA was recovered from a biopsy sample and used to determine the causative species as Spirometra erinaceieuropaei through sequencing of the cox1 gene. From the same DNA, we have produced a draft genome, the first of its kind for this species, and used it to perform a comparative genomics analysis and to investigate known and potential tapeworm drug targets in this tapeworm.

Rosette-forming glioneuronal tumor with dissemination throughout the ventricular system: a case report.

A 33-year-old female was found to have a rosette-forming glioneuronal tumor (RGNT) occurring within the fourth ventricle with multifocal extension to the third and lateral ventricles. She presented with headaches, blurred vision, nausea, and intermittent dizziness. A brain magnetic resonance imaging (MRI) scan showed hydrocephalus and multifocal nodules throughout the ventricular system with the largest mass occupying the fourth ventricle.
