“…[ 1 , 11 , 14 ] The presence of a lucent dural line on CT scans could indicate a subdural origin, which is considered a key feature for the differential diagnosis between subdural osteomas and meningiomas. [ 22 ] On MRI examination, these tumors appear mostly as low-intensity lesions on T1-weighted images and show either a mixed low and high intensity or a homogeneous hyperintensity on T2WI. Adipose tissue within the lesion can sometimes cause a hyperintense appearance on T1WI and serve as an additional element in the differential diagnosis with meningioma.…”

Background: Subdural osteomas represent an extremely rare entity with only 20 cases described to date. Despite the typical benign behavior, these tumors can grow to compress the brain and occasionally detach from the dura mater. Methods: A systematic search of the literature was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After screening for duplicates, 179 publications met the eligibility criteria. Finally, 18 manuscripts were included in this review. Moreover, a detailed description of an illustrative case is provided. Results: The median age at diagnosis was 43.2 years, showing a female prevalence. The inner table of the frontal bone was reported as the most frequent location, and in six cases, the lesions did not show any relation with the dura, which appeared intact. Surgical resection appears to be an effective and safe management option. In the present work, the case of a 60-year-old female who presented with persistent, diffuse headaches which had first occurred 6 months earlier is described. On admission, the physical and neurological examinations were unremarkable, and her medical history disclosed no systemic disease, meningitis, or head injury. Computed tomography showed a homogeneous, high-density nodule attached to the inner table of the left middle cranial fossa. Conclusion: In addition to an in-depth case description, the first systematic and qualitative review of the literature on intracranial subdural osteomas using the PRISMA is provided.

“…All the eight reported subdural cases with clinical features [8][9][10][11][12][13][14][15] are discussed in Table 2. Out of these, most cases presented with age more than 50 years, including the present study, except three cases [9,10,14].…”

“…Most of them presented with headaches except three, out of which two presented with intermittent dizziness [ 13 , 15 ] and one with progressive altered mental status [ 12 ]. In the cases of headache, the meningioma was found to be at the anterior cranial fossa (either right or left side).…”

“…In the cases of headache, the meningioma was found to be at the anterior cranial fossa (either right or left side). Among the cases with intermittent dizziness, in one case, the mass was beneath the right parietal bone [ 13 ] whereas, in the other, it was in the middle cranial fossa [ 15 ] (exact location not mentioned). In the case showing altered mental status, the mass measuring 4.5 × 3.7 × 2.5 cm was located on the right side; the middle cranial fossa had a mass effect upon the right-side temporal lobe [ 12 ].…”

Osteomas are most common among all primary bone tumors of skull bones. They are usually asymptomatic due to their small size and slow growth. They are found incidentally on imaging studies for other neurologic symptoms. Osteoma may be single or multiple when present. They should be differentiated from meningiomas, chordomas, schwannomas, and parosteal osteosarcoma by using different diagnostic methods, including histopathologic study.During routine dissection for MBBS students in an 87 years old female cadaver, we found multiple (seven in number) irregular, lobulated bony masses/structures. Their positions were different with respect to the layers of meninges. Some were present between the dura mater and arachnoid mater compressing the adjacent brain tissues forming impressions on them, and some were outside the dura mater. So, into the previously existing classification, we want to add a new variety under the type b category, i.e., mixed type (intraparenchymal, dural, skull vault) as pointed under the subtype V, which is found in our case.

Osteomas are benign slow growing osteogenic tumors mostly arising in the craniofacial region and characterized by the deposition of differentiated and mature either or both cancellous and compact bone. Osteoma accounts for 2-3% of all bone primary tumors with an incidence of 10-12% among all benign skeletal neoplasms. Objective: The objective of this work is to describe a clinical case of an osteoma in the temporomandibular joint diagnosed in the maxillofacial surgery service of the General Hospital of Pachuca in the State of Hidalgo, Mexico. Clinical Case: A 39-year-old female patient who comes to the General Hospital Pachuca, Mexico due to pain and noises in the right preauricular region of 6 years of evolution, with facial asymmetry, mandibular deviation to the left and limited mouth opening. Clinically, facial asymmetry, mandibular deviation to the left, right posterior crossbite, anterior open bite mainly on the affected side, preauricular pain, joint sounds, and limitation of mandibular movements were observed. Radiographic examination revealed a trapezoidal mass measuring 2.5 by 2.0 cm, with alteration of the condyle-mandible anatomy on the right side. An insertional biopsy is performed, reporting an osteoma, and surgical intervention is continued. Conclusion: The osteoma in the temporomandibular joint is a rare lesion, its timely value is essential for its treatment. Surgical resection is the gold standard treatment, which is based on a radical excision that extends to the altered normal bone, with the contextual objective of achieving an optimal aesthetic result by choosing the least invasive surgical treatment possible.
