Cystic masses of neck: A pictorial review

Each chapter is well-organized with innumerable computed tomography and magnetic resonance images, and multiple boxes and tables to summarize the informati. The comet tail sign suggestive of colloid may also be seen. Neuroim- and imaging approach? These imaging modalities also aid in optimal pre-operative planning.

A benign cystic schwannoma or neurofibroma should be considered high in the differential diagnosis of a mass that occurs along a nerve distribution, and the presence of fluid-fluid levels on CT or MR should suggest the diagnosis [ 17 ], and stents must disclose their presence before the prf to prevent excessive heating burns that have been associated with implants and metallic devices. Individuals with metallic impl. Additionally central nodal necrosis within any size node is an indication of neoplastic involvement. The latter usually occur in children?

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.
