[Megadolicobasilar, ulcerative colitis and ischemic stroke].

Megadolichobasilar (MDB) is a rare arterial anomaly consisting of excessive elongation, widening and tortuosity of the basilar artery. It may be associated with different neurological disturbances, including cerebral ischemic stroke, compression of the cranial nerves, hydrocephalus, headache and vertigo. Ulcerative colitis (UC) is an inflammatory bowel disease of unknown aetiology which may be complicated by arterial or venous cerebral illness, among others neurological anomalies.

[Aetiological diagnosis of cerebral infarction in a county hospital].

Introduction: Cerebral infarction (CI) can be classified aetiologically in several different ways using explicit diagnostic criteria. However, the extent to which these diagnostic criteria are actually implemented in clinical practice is unknown. Aims.

[Fever of central origin during stroke].

Introduction: Fever appears in a fourth of stroke, approximately. Its origins, (the most of them are infectious) are unknown in a minority of the cases. Some hypotheses indicate that central mechanisms like hypothalamic lesions or segregation of endogenous pyrogens may be implicated.

[Kinesigenic paroxysmal choreoathetosis: contribution of SPECT].

We report two unrelated patients affected of kinesigenic paroxysmal choreoathetosis (CPC), during a symptomatic period. Routine complementary exams were normal. The 99mTc-HMPAO cerebral SPECT showed hyperactivation in the basal ganglia opposite to the choreoathetosic symptoms and reduced untake in the near parietal and subcortical zones in one case.
