Total dural calcification with secondary hyperparathyoidism: a rare entity.

Area of Science:

• Neurology
• Endocrinology
• Radiology

Background:

• Secondary hyperparathyroidism can cause bone abnormalities, typically osteopenia and osteosclerosis in the skull.
• Skull manifestations often present as a "salt and pepper" or "grains of sand" granular bone texture.
• Extensive dural calcification is an exceptionally rare finding associated with this condition.

Observation:

• A case of total, dense dural calcification was observed in an adult female patient.
• The patient had a history of secondary hyperparathyroidism.
• The observation was documented over a 19-year follow-up period.

Findings:

• The study documents extensive dural calcification, a rare manifestation of secondary hyperparathyroidism.
• This finding contrasts with the more commonly reported "salt and pepper" skull appearance.
• The case provides evidence for the extreme end of skeletal involvement in secondary hyperparathyroidism.

Implications:

• Highlights the potential for severe and rare dural calcification in secondary hyperparathyroidism.
• Suggests the need for vigilance in recognizing diverse skeletal manifestations of endocrine disorders.
• Contributes to the limited literature on extensive dural calcification, aiding future diagnostic and research efforts.
