It is possible to predict the surgical outcome from the radiologic characteristics of the diverticulum. We believe that our findings may have important clinical implications.

We report a case of temporal lobe epilepsy and incomplete Brown-Sequard syndrome of the thoracic cord. Computed tomography and magnetic resonance (MR) imaging showed multiple supratentorial masses with the classical radiological appearances of multifocal dysembryoplastic neuroepithelial tumour (DNET). Spinal MR imaging revealed intradural lipomas, not previously reported in association with multifocal DNET. Presentation and imaging findings are discussed along with classification and natural history of the tumour.

The Blom-Singer valve is a device for facilitating speech in patients who have undergone total laryngectomy. The valve is inserted into a surgically created tracheo-oesophageal fistula. Fitting the valve and determining the correct length and direction of the fistula, although usually straightforward, can be difficult. We describe two patients in whom MR imaging of the fistula tract has aided valve fitting.
