Tentorial and dural calcification with tertiary hyperparathyroidism: a rare entity in chronic renal failure

Abstract

A case of rare calcification of the tentorium cerebelli, the thoracal dura mater of the spine, and the sclera in an adult male patient with tertiary hyperparathyroidism is presented. The often reported feature in the skull is that of a combination of osteopenia and osteosclerosis giving a granular bone texture. Extensive dura calcification with this condition has very rarely been reported. It is the aim of this paper to document the latter in a patient with chronic renal failure and tertiary hyperparathyroidism.

Ectopic ossification in the cranial dura mater in dialysis patients with secondary hyperparathyroidism

“…Developed secondary hyperparathyroidism and soft tissue calcification in addition to that in the dura mater were observed in these cases. Dorenbeck [ 7 ] and Seyahi [ 8 ] have reported their cranial computed tomographic findings, which look quite similar to those of the present case except for subdural haemorrhage. The calcification may have been a potential risk for intracranial haemorrhage [ 4 ], since the adhesion of superficial arteries was observed (Figure 2 B).…”

A radiological study on intra‐ and extra‐cranial calcifications in adults with X‐linked hypophosphatemia and associations with other mineralizing enthesopathies and childhood medical treatment

“…A, D and F), the supplementary assessment of the frontal cephalograms revealed widespread and diffuse radiopacities inside the neurocranium on both sides of the midline. Sporadic cases with calcification of the falx cerebri or of other parts of the meninges have previously been reported in otherwise healthy patients, as well as in a patient with a tertiary hyperparathyroidism . According to the PA cephalograms of the previously mentioned three XLH patients (Fig.…”

“…The potential sites of calcification include the fibrous dura mater sheets, which include the falx cerebri. Extensive calcification of the falx cerebri is a rare condition, which in some cases has been associated with pathology . In addition to intracranial structures, a lateral cephalogram includes a number of extra‐cranial structures related to the cranium, for example the attachment site of the nuchal ligament.…”

New-onset headache in an elderly man with uremia that improved only after correction of hyperphosphatemia ("uremic headache"): a case report

“…His headache was global, persistent, and improved despite continued dialysis. Inadequately treated hyperphosphatemia in CRF leads to secondary hyperparathyroidism and extraosseous calcification of soft tissues [ 5 , 6 ]. Ingested calcium is deposited in extraosseous sites, possibly because it cannot be deposited in bones [ 7 ].…”
