ICD-10: M85.2

Clinical Description of ICD-10 Code M85.2: Hyperostosis of Skull

Overview of Hyperostosis of Skull

Hyperostosis of the skull, classified under ICD-10 code M85.2, refers to an abnormal thickening of the skull bones. This condition can result from various underlying factors, including metabolic disorders, trauma, or other pathological processes. The thickening can lead to changes in the shape of the skull and may potentially compress adjacent structures, including the brain.

Etiology and Pathophysiology

Hyperostosis can arise from several causes:

• Metabolic Disorders: Conditions such as Paget's disease of bone can lead to abnormal bone remodeling, resulting in hyperostosis.
• Trauma: Previous injuries to the skull may trigger localized bone growth as part of the healing process.
• Infections: Osteomyelitis or other infections affecting the skull can lead to reactive bone formation.
• Genetic Factors: Certain hereditary conditions may predispose individuals to abnormal bone growth.

The pathophysiology involves an imbalance between bone resorption and formation, leading to excessive deposition of bone tissue. This can result in increased density and thickness of the skull bones.

Clinical Presentation

Patients with hyperostosis of the skull may present with:

• Headaches: Due to increased intracranial pressure or irritation of surrounding tissues.
• Neurological Symptoms: Depending on the extent of the thickening and any associated compression of neural structures, symptoms may include visual disturbances, hearing loss, or cognitive changes.
• Palpable Changes: In some cases, the thickened areas of the skull may be palpable upon examination.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies:

• Imaging Techniques: CT scans or MRI can provide detailed images of the skull, revealing areas of hyperostosis and helping to assess any associated complications.
• Laboratory Tests: Blood tests may be conducted to identify underlying metabolic disorders or infections.

Management and Treatment

Management of hyperostosis of the skull focuses on addressing the underlying cause and alleviating symptoms:
