“…Dural arteriovenous malformations (AVMs), which arise following sinus thrombosis or occlusion, are acquired abnormalities. [28][29][30] The static bone cavity may be formed as a result of dilatation of the accessory foramen due to the vascular lesion derived from the branch of the facial artery mimicking dural AVM. A biopsy may be necessary to rule out other pathologic lesions in the static bone cavity of the anterior mandible.…”

This study presents the radiographic findings of two cases of static bone cavity in the inferior aspect of the condylar neck and mandibular notch of the mandible. On plain CT, a soft tissue mass was observed in each cavity. The submandibular gland and the other glands were not found in each cavity. On contrast-enhanced CT, the soft tissue in the cavity in the inferior aspect of the condylar neck had marked linear enhancement and dilated vasculature structure was observed in the cavity. On the contrast-enhanced MRI, the soft tissue in the cavity of the mandibular notch had marked enhancement and flow void was detected in the cavity. In the inferior aspect of the condylar neck, the cavity size had enlarged radiographically over a period of three years. Vascular lesions were found in the cavity located in the inferior aspect of the condylar neck and mandibular notch of the mandible by both CT and MRI. The vascular lesion might explain the enlargement of the static bone cavity.

“…Giant aneurysms usually present clinically as spaceoccupying lesions and differ from the presentation of the common and medium-sized aneurysms 6,19) . Thus, giant intracranial aneurysms may occasionally be mistaken for tumors 2,3,5,7,21) . Giant aneurysms typically appear on computerized tomography (CT) as rounded or oval-shaped masses with distinct outlines.…”

“…Giant aneurysms can cause osseous erosion of the skull base and may occasionally extend to the parapharyngeal space, paranasal sinuses, or infratemporal fossa. 133 Their imaging characteristics may be misleading, with heterogeneous signal intensities and incomplete enhancement owing to thrombosis and blood at various stages. Areas of profound T2 hypointensity within a skull base mass may represent a vascular flow void, and the lesion should be carefully scrutinized to rule out an aneurysm.…”

The skull base is a complex anatomical region that harbors many important neurovascular structures in a relatively confined space. The pathology that can develop at this site is varied, and many disease processes may present with similar clinical and neuroimaging findings. While computed tomography maintains a role in the evaluation of many entities and can, for instance, delineate osseous erosion with great detail and characterize calcified tumor matrices, magnetic resonance imaging (MRI) is the mainstay in the neuroimaging assessment of most pathology occurring at the skull base. Various MRI sequences have proven to be robust tools for tissue characterization and can provide information on the presence of lipids, paramagnetic and diamagnetic elements, and tumor cellularity, among others. In addition, currently available MRI techniques are able to generate high spatial resolution images that allow visualization of cranial nerves and their involvement by adjacent pathology. The information obtained from such examinations may aid in the distinction of these disease processes and in the accurate delineation of their extent prior to biopsy or treatment planning.
