DIFFERENTIAL DIAGNOSIS


Common

  • Foreign Body


  • Lipoma


  • Sebaceous Cyst


  • Metastases, Skull


Less Common

  • Epidermal Inclusion Cyst


  • Basal Cell Carcinoma


  • Squamous Cell Carcinoma


  • Edema/Anasarca


  • Hemangioma


  • Venolymphatic Malformations


  • Neurofibromatosis Type 1


  • Lymphoma


  • Langerhans Cell Histiocytosis


Rare but Important



  • Sinus Pericranii


  • Atretic Cephalocele


  • Sarcoma (Kaposi, etc.)


ESSENTIAL INFORMATION


Key Differential Diagnosis Issues



  • Density of mass on NECT helpful



    • Hyperdense: Acute subgaleal hematoma


    • Fat density: Lipoma, dermoid cyst


    • Fluid density: Sebaceous cyst, epidermal inclusion cyst


  • Enhancing mass + skull changes: Metastasis, squamous/basal cell carcinoma


Helpful Clues for Common Diagnoses



  • Subgaleal Hematoma



    • Not confined by cranial sutures


    • Traumatic, post-surgical


  • Lipoma



    • Well-defined fat density/signal intensity


  • Sebaceous Cyst



    • Often fluid density/intensity


  • Metastases, Skull



    • Destructive skull lesion with associated scalp mass


Helpful Clues for Less Common Diagnoses
