Learning objectives: - To illustrate the MRI features of slow flow vascular malformations. - To emphasize the importance of recognizing the non-neoplastic nature of these lesions. - To highlight their natural history and the therapeutic indications.
Background: Types of vascular malformations are differentiated from one another on the basis of their gross and histopathologic characteristics. Traditionally, intracranial vascular malformations are grouped into the following four groups by Newton and Troost: 1. Arteriovenous malformations are by far the mos[...]
Findings and procedure details: Radiographically, high resolution MR imaging is the diagnostic tool of choice for detecting and identifying slow flow vascular malformations. Developmental Venous Anomaly Developmental venous anomalies (DVA) are the most commonly encountered cerebral vascular malformations. In a serie[...]
Conclusion: Despite the variable etiologies of slow flow vascular malformations of the brain, their MRI manifestations seem to indicate a final common pathway of chronic hematoma. These lesions are quite distinct from tumors, the usual clinical considerations in the differential diagnosis.
