Differential Diagnosis of a Neck Lump (Based on Cervical Lymph Node Levels)
Evaluation of a neck lump with anatomical localisation according to cervical lymph node levels, as each region has characteristic differential diagnoses.

IA (Submental)
Common causes include:
-Reactive/enlarged lymph node
-Thyroglossal duct cyst
-Dermoid cyst
-Plunging ranula

IB (Submandibular)
Differentials include:
-Submandibular gland pathology (sialadenitis, neoplasm)
-Lymphadenopathy
-Cystic hygroma / lymphangioma (may involve extensive neck spaces)

II (Upper Jugular)
Important considerations:
-Metastatic or reactive lymph node
-Parotid gland pathology
-Branchial cleft cyst
-Parapharyngeal space lesions (e.g., paraganglioma, nerve sheath tumours)

III (Mid Jugular)
Possible causes:
-Lymph node enlargement
-Branchial cyst
-Parapharyngeal pathology
-Laryngocoele

IV (Lower Jugular)
Includes:
-Lymphadenopathy
-Virchow’s node (left-sided) suggesting possible abdominal/thoracic malignancy

V (Posterior Triangle)
Differentials:
-Lymph node enlargement
-Lipoma
-Cervical rib

VI (Anterior Compartment)
Usually related to thyroid and central neck structures:
-Thyroid gland pathology
-Thyroglossal duct cyst
-Parathyroid neoplasm
-Lymph node metastasis
-Direct extension of laryngeal malignancy

A structured approach based on neck level anatomy helps narrow the differential diagnosis and guides appropriate investigations such as ultrasound, FNAC, and cross-sectional imaging.
