Methods: The brain CT scans of consecutive patients (age range: 0\u201315 years) who had visited Sultan Qaboos University Hospital, Muscat, Oman, from January 2017 to December 2020 were retrospectively assessed for the presence of PICs. The presence of calcifications was identified using 3 mm-thick axial images and coronal and sagittal reformats. Results: A total of 460 patients were examined, with a mean age of 6.54 \u00b1 4.94 years. The frequency of PIC in boys and girls was 35.1% and 35.4%, respectively. PICs were most common in choroid plexus, observed in 35.2% (age range: 0.4\u201315 years, median: 12 years) of subjects, followed by the pineal gland in 21.1% (age range: 0.5\u201315 years, median: 12 years) and the habenular nucleus in 13.0% of subjects (age range: 2.9\u201315 years; median: 12 years). PICs were less common in falx cerebri, observed in 5.9% (age range: 2.8\u201315 years; median: 13 years) of subjects, and tentorium cerebelli, observed in 3.0% (age range: 7\u201315 years, median: 14 years) of subjects. PICs increased significantly with increase in age (P &lt;0.001). Conclusion: Choroid plexus is the most frequent site of calcification. Choroid plexus and pineal gland calcifications may be present in infants younger than one year. Recognising PICs is clinically important for radiologists as they can be mistaken for haemorrhage or pathological entities such as neoplasms or metabolic diseases.<\/jats:p>","DOI":"10.18295\/squmj.9.2022.058","type":"journal-article","created":{"date-parts":[[2022,9,21]],"date-time":"2022-09-21T23:55:52Z","timestamp":1663804552000},"page":"227-232","source":"Crossref","is-referenced-by-count":4,"title":["Physiological Intracranial Calcifications in Children: &lt;i&gt;A computed tomography-based study&lt;\/i&gt;"],"prefix":"10.18295","volume":"23","author":[{"given":"Faiza","family":"Al Hajri","sequence":"first","affiliation":[{"name":"Radiology Residency Program, Oman Medical Specialty Board, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Srinivasa R","family":"Sirasanagandla","sequence":"additional","affiliation":[{"name":"Department of Human & Clinical Anatomy, College of Medicine & Health Sciences, Sultan Qaboos University, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ammar","family":"Boudaka","sequence":"additional","affiliation":[{"name":"Department of Basic Medical Sciences, College of Medicine, Qatar University, Doha, Qatar; Department of Physiology, College of Medicine & Health Sciences, Sultan Qaboos University, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Humoud","family":"Al Dhuhli","sequence":"additional","affiliation":[{"name":"Department of Radiology & Molecular Imaging, College of Medicine & Health Sciences, Sultan Qaboos University, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eiman","family":"Al Ajmi","sequence":"additional","affiliation":[{"name":"Department of Radiology & Molecular Imaging, College of Medicine & Health Sciences, Sultan Qaboos University, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7681","published-online":{"date-parts":[[2023,5,31]]},"container-title":["Sultan Qaboos University Medical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/5278\/3525","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/5278\/3525","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,11,3]],"date-time":"2026-11-03T09:35:41Z","timestamp":1793698541000},"score":1,"resource":{"primary":{"URL":"https:\/\/mjournal.squ.edu.om\/home\/vol23\/iss2\/12"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,5,31]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2023,5,31]]}},"URL":"https:\/\/doi.org\/10.18295\/squmj.9.2022.058","relation":{},"ISSN":["2075-0528"],"issn-type":[{"value":"2075-0528","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,5,31]]}}}
