Complete Heart Block with Diastolic Heart Failure and Pulmonary Edema Secondary to Enlarging Previously Diagnosed Thrombosed Aneurysm of Sinus of Valsalva in a Patient with History of Autosomal Dominant Polycystic Kidney Disease

Figure 5

CT of the head without contrast. The ventricles and sulci are prominent, most consistent with global cerebral volume loss. Hypoattenuation of the periventricular white matter is most consistent with chronic small vessel ischemic disease. There is no evidence for intraparenchymal mass lesion or hemorrhage. A large CSF-density space (blue line) is seen posterior to the midline cerebellum, measuring 5.0 × 2.9 cm in image 29 of series 2, most consistent with arachnoid cyst. The gray-white junction is intact. Mild polypoid mucosal thickening is seen within the left maxillary sinus. Mild mucosal thickening is also seen within the right sphenoid sinus. A large right mastoid effusion is seen.
