Anatomy
Anatomical ConsiderationsProminent LandmarksTriangles of the NeckRegional AnatomyLymph Node LevelsCarotid BulbTransverse Process of C1
Historical Points.Age:
Up to 15yrs (pediatrics) more than 90% benign16 to 40 (young adult) More than 40yrs (older adults) 80% neoplasm 80% of them malignant (secondary>>primary)
Time courseimmunodeficiency
Prior trauma
Travel, Irradiation, Surgery
Associated symptoms fever, dysphagia, weight loss, otalgia,
hearing loss, respiratory difficulties
Perform a FULL head and neck examination
Neck Masses:EpidemiologyAdult neck masses are 90% malignantPediatric neck masses are rarely malignant.Most common neck mass in children is anenlarged reactive lymph node 2ry tobacterial/viral infectionsAlmost 50% of all 2 Y/O children havepalpable normal cervical lymph nodes
Identification of Neck Masses OnBasis Of Their LocationAnterior Neck SwellingsLateral Neck SwellingsPosterior Neck SwellingsDiffuse Neck Swellings
Identification of Neck MassesOn Basis of their location:
Submental (Inframyelohyoid) dermoid.
Lipoma.
Submental lipoma
Thyroglossal duct cyst TGDC.
Submental metastatic lymph nodes with rim enhancement.
Midline Thyrohyoid Region Supraglottic Carcinoma.
Midline Thyrohyoid Region Metastatic PTC
Chondrosarcoma of the Hyoid. Bone.
Midline (Pre-laryngeal/Laryngeal) Thyroid (Pyramidal Lobe PTC).
Midline (Suprasternal & Pretracheal) Jugular Vein Phlebectasia.
PTC metastasis in a Para-tracheal L.N.
Anterior Paramedian Region, laryngeal tumour.
Submandibular Sialadenitis.
Granulomatous Lymphadenitis(Sarcoidosis).
Lymphoma
Submandibular Lipoma.
Plunging Ranula.
CECT (A) shows a low density lesion in the sublingual space (arrow) that extends posterior medial to the SMG(B).
Phlepoectasia (Common facial V)
T.B. Parotitis & Lymphadenitis
Atypical Mycobacterial Cervical Lymphadenitis.
2nd Arch Branchial Cleft Cysts
Branchial Cyst
Metastatic Lymph Nodes at carotid triangle.
B-Cell Lymphoma at carotid triangle.
Sympathetic Schwannoma Neurofibroma
Laryngomucocele
Posterior triangle L.N. enlargement may be due to; TB.
Supraclavicular lymph nodes..
