Investigating hyperostosis frontalis interna: a computed tomography analysis and predictive model for Hershkovitz classification.
Acta Radiol
February 2025
Department of Medical Imaging, University of Arizona College of Medicine, Tucson, AZ, USA.
Background: Axial computed tomography (CT) cross-sections offer an accessible model for assessing diverse pathologies associated with hyperostosis frontalis interna (HFI) based on the Hershkovitz classification.
Purpose: To delineate the CT characteristics of HFI, emphasizing a radiological description using the Hershkovitz classification. It investigated whether the Hershkovitz classification can be predicted using density, a variable unexplored in the literature.

Article Synopsis
- Uremic leontiasis ossia (ULO) is a rare condition linked to renal osteodystrophy in patients with end-stage chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPTH), causing bone deformities that can lead to a 'leonine' facial appearance.
- The case study focuses on a 39-year-old female patient undergoing treatment, who exhibited significant symptoms and had elevated parathyroid hormone (PTH) levels, confirmed by CT scans.
- Treatment involves a multidisciplinary approach including surgery and management of SHPTH to correct anatomical issues and prevent further complications.
Hyperostosis Frontalis Simulating Metastatic Deposits: Unmasked on SPECT-CT.

Skeletal scintigraphy has a pivotal role in detecting a number of bone pathologies, but it has its own limitations because of 2D image acquisition. Hybrid imaging acts as a savior in these cases where it is difficult to distinguish between benign and malignant lesions just on the basis of planar images. We present one such case of known breast carcinoma with abnormal increased radiotracer uptake in the skull which was difficult to characterize as benign lesion such as hyperostosis frontalis or metastatic osseous lesion.

Objective: The objective of this retrospective study was to identify the uptake patterns and suggest a quantitative method to detect hyperostosis frontalis interna (HFI) on fluorine-18 sodium fluoride ([ 18 F]NaF) PET/computed tomography (CT).
Methods: Between January 2019 and December 2021, patients who underwent [ 18 F]NaF PET/CT with a BMI of 30 and above, were included. Three nuclear medicine consultants reviewed the studies to determine the presence and identify the uptake patterns of HFI.
