Diagnosis: Swelling, mass, or lump in head and neckClinical question: L trapezius mm mass, suspect lipoma, bu growingSigns and Symptoms: L trapezius mm mass, suspect lipoma, bu growing There is a 53 x 26 mm axial dimension mass hyperintense on T1 which suppresses on fat-suppressed imaging compatible with a lipoma located along the left neck posteriorly adjacent to the left trapezius muscle.Within the suprahyoid neck on the basis of size criteria for lymphadenopathy no lymphadenopathy is appreciated. Within the infrahyoid neck on the basis of size criteria for lymphadenopathy no lymphadenopathy is appreciated. The jugulodigastric nodes measure up to 14 mm short axis dimension.There is a left axillary lymph node present measuring 14 mm short axis dimension.Within the visceral space the thyroid gland appears intact. There is a lesion along the right thyroid gland lobe posteriorly measuring 12 mm in diameter which is bright on T2-weighted imaging and intermediate signal on T1-weighted imaging..The airway appears patent.The visualized intracranial structures which include the posterior fossa are intact. The visualized portions of the orbits and paranasal sinuses are intact. The paranasal sinuses demonstrate partial opacification of the right maxillary sinus and scattered opacities in the ethmoid air cells and right frontal sinus. The mastoid air cells are clear.The parotid and the submandibular glands appear intact.The visualized lung apices appear clear.The carotid and vertebral vasculature visualized on this exam appears intact.The cervical vertebral bodies in general are intact. There is a left paramedian disc protrusion present at C5-6 associated with some encroachment of the left-sided exiting nerve roots is a disc bulge at C6-7 associated with encroachment of the neural foramina.
1.There is a lipoma present along the left posterior neck adjacent to the left trapezius muscle.2.There is a small right thyroid gland lobe lesion present which on MRI is nonspecific. Please correlate with the patient's clinical symptoms and signs.3.There are degenerative changes present in the cervical spine worse at C5-6 where there is encroachment of left-sided exiting nerve roots due to disc protrusion.
