“…These include the presence of homogeneous regions of T2 hyperintensity (venous lakes), phleboliths (seen as signal voids on MRI and calcifications on CT), sequential contrast enhancement, often in a centripetal manner, and the absence of any invasive features, which were all were present in our patient, strongly supporting a diagnosis of venous malformation. [2][3][4] Furthermore, increased blood pool activity as evidenced by focal increased activity on the technetium Tc 99m-labeled RBC SPECT study confirmed the diagnosis. Differential diagnosis of masticator space lesions can be broad and include vascular malformations, inflammatory, infectious, and neoplastic processes.…”

“…Other common locations of venous malformation in the head and neck include the periorbital space and the subcutaneous tissues. 3 Venous malformations can be identified reliably using a combination of clinical presentation and imaging features and are considered "do not touch" lesions not needing a biopsy to establish the diagnosis.…”

“…[1] Following further refinement by multiple contributors, the modern classification scheme for vascular anomalies was accepted by the International Society for the Study of Vascular Anomalies (ISSVA) in 1992. [123456] Understanding this classification is necessary for proper interpretation of imaging features of the lesions. While infantile hemangiomas represent vascular tumors evolving a few weeks after birth, vascular malformations (VMs) are present at birth and grow proportionally with the growth of the child.…”

Vascular lesions of the head and neck region in children constitute an interesting group of lesions that benefit immensely from imaging techniques. Imaging is essential for identification, characterization, and delineation of the extent of lesion and subsequent follow-up. Infantile hemangiomas, which are vascular tumors with a specific evolution pattern, constitute a large majority of these lesions. On the other hand, there are vascular malformations, which are anomalies of the vascular system, consisting of a range of vascular tissues associated with various flow patterns. When diagnosis is clinically evident, imaging should utilize non-radiation techniques and address the issues necessary for management. Timing and interpretation of imaging methods employed in assessing childhood vascular lesion should also take into consideration the natural history so that imaging is performed to address a specific question. This review highlights the typical appearance of a hemangioma and a group of vascular malformations of the head and neck. For descriptive purpose, an attempt has been made to group lesions into specific subsites, with each one having specific clinical significance. Cases included illustrate the spectrum of the disease ranging from classical form in young children to slightly differing manifestations of the disease in adolescents and adults. The illustrations also provide a novel way of presenting image data using volume-rendering techniques of 3D data. Multi-modality team interaction and management strategies of these complex lesions are also emphasized.

“…Hemangiomas tend to have a low signal on T1-weighted images and a bright signal on T2-weighted images. Flow voids of blood vessels within the mass and intense contrast enhancement are fairly characteristic [25].…”

“…High flow arterial malformations are uncommon in the masticator space. On MR imaging, it appears as multiple signal voids which represent dilated tortuous hypertrophied vascular structures [15,25]. Time resolved imaging of contrast kinetics (TRICKS) MRA better delineates the arterial feeder, venous drainage, and nidus of high flow arterial vascular malformations [34].…”

We aim to review the normal anatomy and imaging appearance of masticator space lesions. Because the masticator space is not amenable to direct examination, cross-sectional imaging with computed tomography and magnetic resonance imaging play an important role in diagnosis and characterization of lesions occurring there. Masticator space lesions can be classified on the basis of their origin into the following categories: inflammatory lesions, benign tumors, malignant tumors, vascular lesions, and developmental lesions. A diverse spectrum of malignant tumors and benign lesions are seen extending from the adjacent spaces. In addition, one should also be familiar with pseudolesions as well as post-treatment changes in the masticator space that can be mistaken for pathologic conditions.
