1/2. Early spontaneous regression of a hypothalamic/chiasmatic mass in neurofibromatosis type 1: MR findings.A patient with neurofibromatosis type 1 was found to have an enhancing mass in the hypothalamus and in the anterior optic pathway. A 3-month MR study showed a reduction in the size and enhancement of the mass. At a 9-month MR follow-up the mass disappeared and ceased to enhance. This report shows the unusual behaviour of a hypothalamic/chiasmatic mass confirming that in such asymptomatic cases the conservative management can be considered the treatment of choice.- - - - - - - - - - ranking = 1keywords = behaviour (Clic here for more details about this article) |
2/2. Thalamic tumour presenting as frontal lobe dysfunction.A 64-year-old man presented with a change in personality and behaviour but with no neurological deficits. He exhibited impaired executive functions, apathy, unsteadiness of gait and falling; he lacked insight and exhibited purposeless behaviour, making loud grunting noises. A CT scan at 6 months revealed no abnormality, but at 9 months CT and MRI showed a bilateral thalamic tumour. The presenting symptoms had similarities to frontal lobe dysfunction progressing to dementia.- - - - - - - - - - ranking = 2keywords = behaviour (Clic here for more details about this article) |
