This article reviews and illustrates the anatomy and pathology of the masticator space MS. Pathology of the masticator space includes inflammatory conditions, vascular lesions, and tumours. Intrinsic tumours of this space can be benign and malignant, and they may arise from the mandibular ramus, the third division of the trigeminal nerve, or the mastication muscles. Malignant tumours may appear well defined and confined by the masticator fascia, without imaging signs of aggressive extension into neighbouring soft tissues. Secondary invasion of the masticator space can also occur with tumours of the nasopharynx, oropharynx, oral cavity, and parotid glands. Perineural tumour spread PNS , especially along the trigeminal nerve, can also occur with masticator space malignancies. Masses of the MS are difficult to evaluate clinically, and computed tomographic CT and magnetic resonance MR images are essential for the diagnosis and characterisation of these lesions.
