Strap muscles radiology. Differential Diagnosis: Thyroglossal duct cyst (by far most likely by location and Paramidline thyroglossal duct cyst. MANCUSO IMAGING APPROACH Techniques and Relevant Aspects Computed Tomography A discussion of the use of computed tom…. The hyoid bone is at vertebral level C3. The lesion is just below the level of the hyoid bone with a small suprahyoid extent into the pre-epiglottic fat. It surrounds the front and sides of the visceral space and is related posteriorly to the carotid space. Relations anteriorly: strap muscles posteriorly: thyroid cartilage, cricoid cartilage, trachea posteromedially: tracheo-esophageal groove (containing lymph nodes, recurrent laryngeal nerve, parathyroid glands), inferior thyroid artery posterolaterally: carotid space 3 Arterial supply superior thyroid artery (from the external carotid artery) The document discusses the anatomical spaces of the neck region. LARYNX: INTRODUCTION, NORMAL ANATOMY, AND FUNCTION ROBERT HERMANS AND ANTHONY A. They are all attached to the hyoid bone and look like a strap. 3). The anterior cervical space is located deep to the strap muscles and sternocleidomastoid muscle. Contrast-enhanced CT at the level of the thyroid cartilage reveals a cystic mass in the anterior neck (arrows), inseparable from the strap muscles (s), with septation and a lobular mural nodule (n). Papillary thyroid carcinoma of the thyroglossal duct. They act mainly to depress the hyoid bone and larynx during swallowing and speech. The infrahyoid muscles (a. Checking the security of your connection, please wait Dec 7, 2009 · It is a group of four pairs of muscles in the anterior part of the neck: the sternothyroid, sternohyoid, thyrohyoid and omohyoid muscles. The thymus descends from the third pair of pharyngeal pouches along with the inferior parathyroid gland. In this article, we shall look at the anatomy of the infrahyoid muscles – their attachments, actions and innervations. The sternocleidomastoid muscle is typically displaced posteriorly or posterolaterally. In some cases, thyroglossal duct cysts may be embedded in the infrahyoid (strap) muscles. Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. a Axial contrast-enhanced CT images of the infrahyoid neck demonstrate a well-circumscribed homogenous low attenuation mass located between the thyroid cartilage (arrowhead) and strap muscle (arrow). a. The thin, flat muscles connecting the ante- rior aspects of the hyoid bone, thyroid carti- lage, and sternum are collectively called the strap muscles (see Fig. The 2 most common complications of TDC are infection and malignancy, the latter of which occurs in 1-4% of cases. Thyroglossal duct cyst (TDC) is usually diagnosed clinically, but ultrasonography is the preferred imaging technique in children. It describes the key spaces in the suprahyoid and infrahyoid neck, bounded by layers of deep cervical fascia. k. Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Thyroglossal Duct Cyst Findings: Axial neck CT images with contrast demonstrate a fluid density lesion at midline embedded within the strap muscles, displacing the adjacent strap muscles. Lateral Pharyngeal Recess Parotid Gland (Superficial and Deep lobes separated by VII) Rectus capitis anterior Muscle Lateral Pterygoid Muscle Nasopharynx Longus Colli Muscle Lateral Pterygoid Plate Changes in and around the SCM muscle are routinely seen and include posterior and medial displacement of the muscle, distortion and flattening of the muscle, or atrophy, despite surgical preservation of spinal accessory nerve. MRI T1: variable Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Understanding these neck spaces fig 1. In rare case, enhancing solid components or calcification within the cyst may raise suspicion of malignancy, usually papillary carcinoma 11. Nov 6, 2025 · The arterial supply to the infrahyoid muscles is via the superior and inferior thyroid arteries, with venous drainage via the corresponding veins. Because the inferior parathyroid gland is most commonly located on the posterolateral aspect of the lower thyroid pole, deep in relation to the strap muscles, it is only natural that a remnant of thymus is seen deep in relation to the same muscles. This includes the parapharyngeal space, masticator space, buccal space, parotid space, carotid space, retropharyngeal space, perivertebral space, visceral space and anterior cervical space. the strap muscles) are four paired muscles located in the anterior neck, below the hyoid bone. b Coronal contrast-enhanced CT image shows the paramidline location and extension to upper pole of the left Deep and anterior to the sternocleidomastoid muscle are the thin, infrahyoid “strap” muscles that are named by their attachments: omohyoid (reflected on one side); sternohyoid; and deep to these, the sternothyroid and thyrohyoid muscles. m4xsec, c0ng, yqwzr, 2r92x, wdnru1, og5ie, jnrp, 6490hl, koyte, vrqkkl,
