A 34 year-old woman presented with headaches and a mild receptive aphasia, two weeks following labor and delivery.

Magnetic Resonance Venogram (upper left); Coronal T1 MRI (upper right); Axial T1 MRI scans (lower left and lower right). In the MRV, note the absence of the left transverse and sigmoid sinus. In the coronal scan, a clot is seen within the left transverse sinus. In the lower images, a bright signal is seen in the posterior temporal lobe, indicated a subacute hemorrhage, explaining the patient's receptive aphasia. Venous infarcts are uncommon; they occur in patients who are hypercoagulable (post-partum, on hormone replacement, have an underlying malignancy, or are born with a genetic disorder). Venous infarctions are often hemorrhagic.
