RT Journal Article SR Electronic T1 Spontaneous intralesional haemorrhage in dysembryoplastic neuroepithelial tumours: a series of five cases JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 97 OP 101 DO 10.1136/jnnp.67.1.97 VO 67 IS 1 A1 Maria Thom A1 Beatriz Gomez-Anson A1 Tamas Revesz A1 William Harkness A1 Ciaran J O’Brien A1 Rupert Kett-White A1 E Wyn Jones A1 John Stevens A1 Francesco Scaravilli YR 1999 UL http://jnnp.bmj.com/content/67/1/97.abstract AB Five patients with dysembryoplastic neuroepithelial tumour (DNT) showing extensive secondary haemorrhage, a finding not previously associated with these neoplasms, are described. The clinical presentations, neuroimaging findings, and histopathological features of these patients are reviewed. One patient, a previously asymptomatic 12 year old girl, presented with an acute intracerebral haemorrhage into a DNT. A further four young adults with histories of intractable partial and generalised seizures dating from childhood showed significant chronic haemorrhages within DNT, the MRI appearances in one patient giving a false impression of a cavernoma. Histopathology disclosed vascular abnormalities within these tumours which, together with other factors discussed, may have predisposed these tumours to haemorrhage.
