Cerebral venous sinus thrombosis (CVST) is a rare disease with a variety of symptoms, diagnosed primarily in imaging studies which allow early introduction of proper, causal treatment.

To analyze the epidemiological and clinical data and the results of imaging studies performed in patients diagnosed with this disease.

Material and Methods:
The analyzed material consisted of a group of 16 patients (11 women and 5 men) who were examined with CT and MRI in the Department of Radiology and Diagnostic Imaging at Provincial Hospital No. 2, named after St. Jadwiga the Queen, in Rzeszów during the period October 2000 – October 2012, and who were diagnosed with CVST. At least one of the following imaging examination was performed in these patients: head CT scan with or without intravenous contrast administration, CT angiography of the head, head MRI with intravenous contrast agent, MR venography.

CVST occurred most often in women in two age groups: 20 – 29 and 40 – 49-years-old. The most common risk factors were inflammatory lesions of the head and neck, and slightly less frequent in group of women, oral contraceptives and puerperium. In six patients (37.5%) co-existence of at least two risk factors was observed: 1) thrombotic lesions more often localized in large, paired sinuses, 2) blood clots, observed in multiple locations in the majority of patients, i.e. in 13 patients (81.25%). The greater number of risk factors was associated with a more extensive range of DVT. In eight patients, changes in the sinuses and cerebral veins were associated with various changes in the brain tissue. The level of D-dimers in CVST may be normal. Diagnosis was usually made on the basis of CT angiography examination and, in the second place, on the basis of MR venography.
