Abstract

The authors present a case of giant serpentine aneurysm (a partially thrombosed aneurysm containing tortuous vascular channels with a separate entrance and outflow pathway). Giant serpentine aneurysms form a subgroup of giant intracranial aneurysms, distinct from saccular and fusiform varieties, and in this case, too, the clinical presentation and radiographic features of CT, MR imaging and angiography were distinct.

  Fig. 1 A 50-year-old woman with giant intracranial aneurysm. A. Precontrast CT scan shows a large oval-shaped mass with increased attenuation representing thrombus (arrows) and slight peripheral calcification (arrowheads) in the right frontal region. Peripheral edema may also be observed. B. Postcontrast CT scan demonstrates peripheral and central enhancenment. The enhanced central tubular structure represents the serpentine vascular channel (arrow). C. T2-weighted sagittal image shows a large thrombosed aneurysm (arrows) with peripheral edema (arrowheads) in the right frontal area. D. Postcontrast T1-weighted sagittal image shows an enhancing tubular structure (arrow) indicating the serpentine vascular channel. E, F. Angiograms of the right internal carotid artery. Anteroposterior (E) and lateral (F) arterial-phase angiograms show the ectatic vascular channel involving the upper trunk of the right middle cerebral artery and corresponding to the vascular channel identified on MR images. G, H. Anteroposterior (G) and lateral (H) capillary phase angiograms more clearly demonstrate the tortuous vascular channel of the serpentine aneurysm and show delayed filling of normal cortical branches of the superior division (arrowheads).
