A 1-month-old infant with history of bilateral hydronephrosis and sepsis associated with urinary tract infection was admitted at our institution. During the hospitalization, the patient presented seizures and lethargy. Electroencephalogram was normal. Brain magnetic resonance imaging (MRI) showed enlargement of the transverse and straight sinuses with abnormal high T1 signal and blooming artifact in the gradient-echo (GRE) sequence. Enlargement of the cortical veins suggestive of venous congestion and flow void in a patent falcine sinus was also noted (Fig. 1). MR venography (MRV) demonstrated a flow defect within the straight and right transverse sinus, consistent with venous sinus thrombosis and confirmed flow in a patent falcine sinus (Fig. 2).
Fig. 1
Sagittal and axial T1W images (a, b) show high signal within the straight sinus and right transverse sinus (arrows), axial GRE sequence (c) shows enlargement and blooming artifact in the right transverse sinus (arrow), axial T2W image shows enlargement of cortical veins (arrowhead). Notice the flow void in the falcine sinus (short arrow in e)
Fig. 2
Sagittal T1W post gadolinium (a) shows flow within the superior sagittal sinus and falcine sinus (arrows) and absence of flow in the straight sinus. MRV 3D coronal and sagittal reconstructions (b and c) showed absence of flow in the right transverse sinus and demonstrate flow within the recanalized falcine sinus (arrowheads)
