[The difficulties with the diagnosis of cerebral sinus thrombosis of a young woman - a case report].

UNLABELLED: Cerebral venous stroke is disfunction of brain cause by thrombosis of cerebral veins or thrombosis of sinus of the dura mater. This disease represents about 0,5-1% of all strokes. Women are ill more often. There are over 100 factors which cause this disease. The most often symptoms are headache, epileptic fit, oedema of optic nerve, loss of visual acuity, speech defects. Magnetic resonance proves the diagnosis. MRI with contrast is recommended.

A CASE REPORT: We show the case of a young woman taking the oral contraceptive pill whose only symptom of venous thrombosis for a few days was a strong headache. When the woman was admitted to hospital, she didn't have any other symptoms ( in neurology examine, tomography and blood tests). The severity of headache after lumbar puncture (because of suspected subarachnoid bleeding) suggested presented of post-dural-puncture headache, which delayed the correct diagnosis. It was not until after the symptoms of the focal brain damage appeared on the fifth day that we finally made the correct diagnosis confirmed by some additional tests/examinations. Thus we started causal and symptomatic treatment. The difficulties we had with making the correct diagnosis indicate that the recognition of cerebral thrombosis should be taken into account when treating every young woman taking contraceptive pills and suffering from strong headaches. Headaches can be the only symptom of venous stroke in 90% of cases.
