[Cerebral venous thrombosis: Clinical and radiological features, about 62 cases]

The work's purpose is to make a general review on the various clinical-radiological aspects and the management of cerebral venous thrombosis (CVT) in our hospital and compare them to those described in the literature.

MATERIAL AND METHOD

Our series included 62 patients aged over 18 years, collected over 7 years (2009-2016) in the radiology department of the CHU Hassan II of Fez (Morocco), in which the radiological diagnosis of TVC was retained. Our patients have benefited from a brain CT scan and brain MRI. Clinical and radiological characteristics and post-treatment progression were described.

RESULTS

The average age was 35 years with a female predominance; sex ratio 3.76 (49F/13H). The symptomatology was non-specific, made mainly of headaches, comic crises, disturbances of consciousness and focal signs. The upper longitudinal sinus was dominant topography (51.61%). The etiological factors were varied: infectious (sinusitis, chronic otitis media, oto-mastoiditis, bacterial meningitis, and septicemia), gyneco-obstetrical (oral contraception, pregnancy, and postpartum), systemic (Behçet diseases, polycythemia of Vaquez, paraneoplastic syndrome, antiphospholipid syndrome), local (head trauma), undetermined etiological factors. The CT scan, but especially the cerebral MRI, made it possible to make the diagnosis but also to direct towards the etiology.

CONCLUSION

Cerebral MRI is currently the best imaging in the diagnosis of CTV, allowing an accurate assessment of its location, extent and impact on the cerebral parenchyma. Multiple conditions are responsible for CTVs. Therapeutic management is based on heparinotherapy and etiological treatment.

[Aorto-cava fistula complicating abdominal aorta aneurysm]

We report here a case of aorto-cava fistula complicating the rupture of a sub-renal aortic aneurysm into the inferior vena cava, which is a rare complication of aortic abdominal aneurysms with often-fatal outcome. Abdominal computed tomography with multi-planar reconstructions remains the firstline-imaging tool allowing positive diagnosis and preoperative planning. Treatment may be surgical or endovascular.
