“…While hyperostosis has been characterized as benign and not causal to clinical disease [2], excessive growth can present with clinical symptoms depending on extent and location. Overgrowth could potentially cause intracranial hypertension [1], localized headache [10], and cranial nerve entrapment [3].…”

“…An affected frontal bone, termed hyperostosis frontalis interna (HFI), comprises a majority of cases with particular prevalence in post menopausal females. HFI is usually an incidental finding and is not known to cause clinical disease [2], although excessive growth can be symptomatic upon brain tissue compression and/or cranial nerve entrapment [3]. Hyperostosis of the sphenoid bone or other bones comprising the floor of the cranium are rare and are generally seen unilaterally in association with intraosseous meningiomas [4,5].…”

Hyperostosis of the internal table of the frontal bone is not an uncommon phenomenon. However, such hyperostosis of the temporal and/or sphenoid bone is rarely discussed in the available literature, especially in the absence of meningioma. We report a case of hyperostosis of the frontal, temporal, and sphenoid bones found during routine cadaveric dissection of an 81 year-old female. Histology revealed thickening and increased density of the lamellar bone. The periosteum was unaffected. Possible etiology is discussed.

“…The presence of bilateral lesions, however, may suggest a more diffuse process, such as an underlying bone remodeling abnormality similar to the abnormalities observed in hyperostosis cranialis interna (HCI), hyperostosis frontalis interna, fibrous dysplasia, or Paget's disease. 6,17,18 HCI is an especially intriguing candidate to explain bilateral calvarial and skull base hyperostosis that is isolated to the cranium. Patients with HCI present with significant thickening of the inner table of the frontal, parietal, occipital, and temporal bones.…”

“…Radiographically, the hyperostotic lesions of the IAC found in HCI resemble exostoses. 17,18 Thus, in patients with diffuse thickening of the inner table across the calvarium there is likely a genetic predisposition to IAC hyperostosis that is compounded by phenotypical factors, such as local inflammation, and aberrant suture closure.…”

Background Exostoses and osteomas are benign, insidious lesions of the bone involving the internal acoustic canal (IAC). We present two cases of IAC exostoses managed with surgical decompression and review the clinical outcomes of previously reported cases in the literature. Methods A comprehensive search was conducted using PubMed Central, Web of Science Core Collection, and Google Scholar databases to identify previous reports of IAC exostoses and osteomas. A total of 26 reported cases were identified, and patient presenting symptoms, management strategies, and response to surgery was obtained when available. Results Of the 13 patients who underwent surgical decompression, 8 patients had resolution of vertigo symptoms, 10 patients had improvement of tinnitus symptoms, and all patients maintained some level of serviceable hearing. Conclusion IAC exostoses and osteomas are rare lesions that lead to insidious onset of debilitating symptoms from vestibulocochlear nerve dysfunction. Although the role of surgical decompression remains unclear, it appears that patients presenting with vertigo have more favorable response to surgical decompression as compared with those presenting with tinnitus and sensorineural hearing loss.

“…Moreover, the differential diagnosis of extensive osseous thickening in the ISFB ranges from such focal masses as meningioma and endosteal osteoma, subdural and dural calcification and to the diffuse skull process including Paget's disease, acromegaly and fibrous dyplasia (14,17,18,24).…”

AIm: Increased thickening of the internal surface of the frontal bone (ISFB) was investigated, regarding possible pressure application to the brain tissue and the changes in bone marrow structure. mATERIAl and mEThods: Morphological analysis of the ISFB was carried out in a total of 300 adult skulls.REsulTs: Type A, defined as normal appearance, has been detected in 243 cranium. In 57 cranium (19%), increased osseous thickening cases with different appearance were observed. The most frequent examples of osseous thickening were present in nodular types (Types B, C) and diffuse types (Types D, E), (29.8%). In fact, an irregular osseous thickening, which is in the form of plaques, was situated on both sides of the origin of sagittal sulcus. Types B and C were seen as small isolated nodules on the ISFB. In the histological analysis of ISFB, it is determined that the endocranium, normally present in a compact bone structure, changed its lamellar and had a nonwoven immature bone structure, in the areas with the characteristic of increased osseous thickening. The thickening of the diploe gap and increasing lamellar bone tissue in the endocranium revealed an increase in vascularization. CoNClusIoN:The nodular and widespread form of increased osseous thickening could apply pressure on to dura mater and the brain tissue.
