Introduction:

Cerebral venous thrombosis (CVT) is a serious disease that most frequently affects young adults, with an incidence of three cases per million adult inhabitants. It is the cause of 0.5% of cerebral vascular events. It is more frequent in women, is associated with childbirth, puerperium and the use of oral contraceptives.

Clinical case:

Female, 34 years old, with 8.2 weeks of gestation, which began seven days prior to admission with intense headache, nausea and vomiting, suggestive of hypertensive skull; went to hospital, where he was admitted with Glasgow 15 points, MRI was performed, which showed thrombosis of the left transverse venous sinus and left parietal temporo intraparenchymal hemorrhage, showed deterioration of neurological status, and required advanced airway management and transfer to Intensive Care Unit. CT (computed tomography) of the skull on admission to the Intensive Care Unit showed parenchymal left parietal temporo hematoma, cerebral edema, collapse of the ipsilateral lateral ventricular system and deviation of the midline. Neurosurgery assessed who ruled out surgical procedure and began osmolar therapy with hypertonic solutions at 7.5%. CT scan five days later showed cerebral infarction in the left hemisphere and old intraparenchymal bleeding in reabsorption process but severe cerebral edema, which required left parietal frontal craniectomy. The control CT scan with decreased edema, achieving weaning from mechanical ventilation, graduated to the floor of gynecology with Glasgow 14 points and pregnancy of 10.2 SDG.

Conclusions:

It is very important the correct diagnosis and not to confuse pregnancy alterations with neurological symptoms. MR is the study of choice.
