| Objective:To study the clinical and imaging features of cerebral developmental venous anomalies (CDVA) and
review the literatures.Methods:Nine cases of CDVA were retrospectively collected from November, 2011 to March, 2014. The clinical
features and imaging examination including computed tomography (CT), magnetic resonance imaging (MRI), and digital subtraction
angiography (DSA) were analyzed and the related literatures were reviewed.Results:(1) Symptoms: Of 9 cases, 4 cases with dizzy(4/9),
4 cases with headache(4/9), 2 cases with nausea(2/9), 1 case with astasia(1/9), 1 case with history of cerebellum hemorrhage, 1 case with
fortuitous findings by ophthalmologic examination (1/9); (2) Location: Of 9 cases, 4 cases with supratentorial lesion (4/9), 5 cases with
infratentorial lesion(5/9); (3) Images modalities: Of 9 cases, 6 cases with CT scan or contrast-enhancement CT( of these, 3 cases with CT
scan, 3 cases with CT scan+contrast-enhancement), 4 cases with MRI ( of these, 1 case with non-contrast MRI, 3 cases with non-contrast
and contrast-enhancement MRI), 3 cases with DSA; (4) Imaging features: The dilated medullary veins (forming a typical caput medusae
sign) and collector veins can be showed no matter contrast-enhancement CT and reconstruction techniques, contrast-enhancement MRI
and SWI image or venous phase DSA.Conclusion:The imaging modalities including CT, MRI and DSA can be employed for the
diagnosis of CDVA. But, the combination and optimal choice of these modalities for different cases is important to clinical practice. |
