Intracranial physiological calcifications evaluated with cone beam CT

Abstract

Intracranial physiological calcifications can be a common finding on CBCT scans, whereas pathological intracranial calcifications are rare.

Serum Prolidase Activity as a Biomarker for Choroid Plexus Calcification

“…Further, majority of physiological calcification occurs in a region occupying 12%-66.2% of CP (Daghighi et al 2007;Sedghizadeh et al 2012). We show here that CPC (which is considered as the physiological calcification) was independent of the calcification markers including Ca, vitamin D, and PTH.…”

“…An increase in the plasma concentration of Ca leads to the calcification of soft tissues (Bender 2009), and intracranial physiological calcification frequently occurs (approximately 35.2%) in adults (Sedghizadeh et al 2012). Further, majority of physiological calcification occurs in a region occupying 12%-66.2% of CP (Daghighi et al 2007;Sedghizadeh et al 2012).…”

Bilateral Extensive Ossification of the Posterior Petroclinoid Ligament: An Anatomical Case Report and Literature Review

“…21,22 Regrettably, the only descriptions of such findings have been obtained through radiologic studies. 13,15,16,21 A radiographic study of the calcification of the interclinoid and petroclinoid ligaments of the sella turcica in 255 subjects by Cederberg et al 15 found partial calcification of the interclinoid ligament in 39% of the subjects and complete calcification in 8%. The analysis of the pPCL revealed 67% of ligaments with no calcification, 23% with partial calcification, and 9% completely calcified ligaments.…”

“…1,12 Ossifications of petroclinoid ligaments are rarely described in anatomical literature, 7,8 with most descriptions of such findings based on radiologic studies. [13][14][15][16] So far, only Kimball et al, 4 Perumal and Gayathri, 11 and Rusu et al 17 have provided observations of ossification of the posterior petroclinoid dural folds on wet specimens. However, these authors focused mainly on the significance of a completely ossified posterior petroclinoid dural fold as a factor potentially relating to trigeminal neuralgia.…”

The need to develop a strategy for managing incidental findings on maxillofacial imaging studies: a call for action

“…6 The consequent need to distinguish clinically important subclinical disease entities having potentially serious medical consequences from benign findings and how to pursue the former has likewise perplexed oral and maxillofacial radiologists; but, unlike the American College of Radiology, the International Association of Dentomaxillofacial Radiology has not yet addressed these issues.…”
