Cervical LNs And Neck Lumps session1 Flashcards
6 structures that drain directly into deep LNs
Infrahyoids, TG, larynx, trachea, Pharynx, oesophagi
5 superficial LNs draining the face scalp and neck
Auricle (era) pre and post auricular
Occiput (occipital bone)
Mental protuberance (chin) Submental
Mandible (jaw) submandibular
Sternocleidomastoid -superficial cervical (EJV) - posterior cervical (EJV) - anterior cervical (AJV)
Deep LNs neck 3
Jugular- digastric anterior to SCM
Jugular-omohyoid mid neck anterior SCM
Supraclavicular LNs within supraclavicular fossa
Deep SCM, closely related IJV and carotid sheath
Waldeyer’s ring
An annular collection of lymphoid tissue surrounding upper aerodigestive
Superior to inferior, Tonsils: 1 pharyngeal (back nasal cavity), 2 tubal, 2 palatine (back of throat), 1 lingual
PTPL protects the people lots
If lumps moves on swallowing/ sticking out tongue
Problem with thyroid gland - attached to pre tracheal fascia, hyoid
Causes of superficial neck lump (within superficial fascia/ skin)
Sebaceous cyst, dermoid cyst, lipoma (movable), skin abcess
Cause of congenital lesions
Thyroglossal cysts (movable, pea size, fluid filled), branchial cyst (anterior border SCM, fluid filled), laryngocoele, pharyngeal pouch
Lateral lumps
Upper 1/2 - branchial cyst (congenital)
Submandibular salivary gland - cancer/ blocked duct, pain eat
Anywhere- lymphadenopathy
Midline lumps
(C) High pea size- dermoid cyst, epithelial lined, movable -> surgery, child
Thryoglossal duct cyst (c), move stick tongue / swallow, child
Thyroid- goitre, move swallow (gland/ cancer/ lump), adult
Red flags for lymphadenopathy
Persisting >6 weeks, fixed/ hard/ irregular, rapidly growing, associated systemic signs, associated with persistent change voice/ hoarseness or difficulty swallowing
Deep supraclavicular LNs
Left node - abdomen and thorax drainage (virchow’s node)
Right node- mid section chest, oesophagus, lungs
