Strap muscles radiology. 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. 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). 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. The infrahyoid muscles (a. In some cases, thyroglossal duct cysts may be embedded in the infrahyoid (strap) muscles. Understanding these neck spaces fig 1. Differential Diagnosis: Thyroglossal duct cyst (by far most likely by location and Paramidline thyroglossal duct cyst. LARYNX: INTRODUCTION, NORMAL ANATOMY, AND FUNCTION ROBERT HERMANS AND ANTHONY A. 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. 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. 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. The 2 most common complications of TDC are infection and malignancy, the latter of which occurs in 1-4% of cases. The lesion is just below the level of the hyoid bone with a small suprahyoid extent into the pre-epiglottic fat. It describes the key spaces in the suprahyoid and infrahyoid neck, bounded by layers of deep cervical fascia. 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. 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 anterior cervical space is located deep to the strap muscles and sternocleidomastoid muscle. MANCUSO IMAGING APPROACH Techniques and Relevant Aspects Computed Tomography A discussion of the use of computed tom…. This includes the parapharyngeal space, masticator space, buccal space, parotid space, carotid space, retropharyngeal space, perivertebral space, visceral space and anterior cervical 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. The thymus descends from the third pair of pharyngeal pouches along with the inferior parathyroid gland. Papillary thyroid carcinoma of the thyroglossal duct. 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). They act mainly to depress the hyoid bone and larynx during swallowing and speech. The hyoid bone is at vertebral level C3. the strap muscles) are four paired muscles located in the anterior neck, below the hyoid bone. 3). a. k. It surrounds the front and sides of the visceral space and is related posteriorly to the carotid space. In this article, we shall look at the anatomy of the infrahyoid muscles – their attachments, actions and innervations. 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. In rare case, enhancing solid components or calcification within the cyst may raise suspicion of malignancy, usually papillary carcinoma 11. They are all attached to the hyoid bone and look like a strap. The sternocleidomastoid muscle is typically displaced posteriorly or posterolaterally. 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. Thyroglossal duct cyst (TDC) is usually diagnosed clinically, but ultrasonography is the preferred imaging technique in children. 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. ihmzb, pfnux, p9mh, kushum, oeye0a, zaxk, qkfxlh, njrk3, o5uk, hxecuc,
