Intradiploic epidermoid cysts, often presenting as scalp lumps, can be diagnosed using plain films. Atypical features require CT and MRI for accurate assessment.

Area of Science:

  • Neurosurgery
  • Radiology
  • Pathology

Background:

  • Intradiploic epidermoid cysts are rare benign tumors.
  • Scalp lumps are the most common clinical presentation.

Purpose of the Study:

  • To review radiological features of intradiploic epidermoid cysts.
  • To discuss differential diagnoses.
  • To evaluate diagnostic imaging modalities.

Main Methods:

  • Retrospective review of 37 intradiploic epidermoid cysts.
  • Analysis of radiological findings on plain films, CT, and MRI.
  • Correlation with clinical presentation.

Main Results:

  • The most common clinical feature was a long-standing scalp lump (67.7%).

  • Plain films are cost-effective for diagnosis, showing well-defined lytic lesions with sclerotic borders (78%).
  • Atypical lesions (>5 cm and/or ill-defined edges, 22%) were best assessed by CT and MRI.

    • Conclusions:

    • Plain films are effective for typical intradiploic epidermoid cysts.
    • CT and MRI are crucial for evaluating atypical presentations.
    • Preoperative diagnosis is often suggested by typical radiological findings.
