This case report deals with a 16-year-old girl, admitted for headache and Jacksonian seizures. The clinical examination showed no gross disturbances, but the neuropsychologic examination revealed difficulties in speech-linked abstract thinking. Extensive radiologic investigations revealed the presence of a frontal intracallosal bony tumor, protruding into the lateral ventricles. Histologic examination of the surgical specimen showed a large benign osteoma, without any connection with dura or skull. In view of the paucity of symptoms, a dysontogenetic etiology of the tumor seems obvious.

In seven patients with intracranial meningioma whose presenting signs and symptoms were ophthalmologic the underlying problem was initially misdiagnosed. Three patients had sphenoidal meningiomas with compression of the anterior visual pathways, but the initial diagnoses were acute optic neuritis, chronic optic neuritis and glaucoma. Two other patients had large frontal meningiomas causing in one case unilateral pain and swelling of the upper lid plus ptosis and hypotropia, and in the other case bilateral frontal morning headaches and intermittent blurring of vision in one eye; they were thought to have a frontal lobe osteoma and migraine respectively. A sixth patient had a large parietal meningioma causing unilateral papilledema in an eye with a corneal graft; the papilledema was not initially recognized because of severe astigmatism in that eye. The last patient had an occipital meningioma that had caused a fixed homonymous field defect and many years of "classic migraine".

A 20-year-old woman presented with a 4-month history of persistent right frontotemporal headache. There were no features of raised intracranial pressure. Plain radiographs of the skull showed a dense calcified mass in the right frontal area. Computed tomography revealed the lesion to be uniformly hyperdense and non-enhancing. Magnetic resonance imaging confirmed the dural origin of the lesion which was hyperintense and non-enhancing. At operation a bony hard intradural mass was confirmed and excised. Histology revealed it to be an osteoma.

A 21-year-old man was admitted to hospital because of recent anosmia and liquorrhoea. He also complained of moderate headache and concentration problems in the past few years. On CT scan and MRI scans a big subfrontal process was seen, partially solid and partially cystic. Neurosurgical and histological findings proved that the lesion was an osteoma of the anterior skull base, concomitant with an intradurally extending mucocele.

The paper reports two rare cases of sphenoidal osteoma which occur statistically in 1.9% of sphenoidal osteomas. Two women underwent computed tomography because of complaints of progressive headaches. The patients had recurrent unilateral exudative otitis media. CT localized the tumor spread into the cerebral cranium and promoted further treatment design. The authors state that indications to CT diagnosis in patients with headaches should be increased. It is also suggested to make CT-diagnosis more frequently in cases of recurrent unilateral exudative otitis.

A case of an eighteen-year-old student, complaining of frontal and periorbital headache is presented. Using conventional radiographies and CT Scan a frontal sinus osteoma is diagnosed, finding a hypodense image located in the left frontal cerebral lobe, without perilesional oedema or contrast uptake. During the surgical act, a destruction of the posterior wall of the left frontal sinus is found, penetrating the anterior cerebral fossa and connecting with the cerebral cavity in the left frontal cerebral lobe through a fistula of mucosal tissue that passes through the dura mater. Complete tumoral exeresis was undertaken as well as plastic reconstruction with excellent clinical and cosmetic results. We conclude that the early diagnosis and treatment of these benign lesions should be undertaken in order to avoid the potential complications they can provoke.

The authors report 10 cases of frontal sinus osteoma. The patient group consisted of 5 men and 5 women, ranging in age from 15 to 60 years. The most common revelating symptom was headache. Treatment depends on tumor size, its course, and complications. Transfacial incision was used in 3 cases and Cairns Unterberger approach in 5 cases. Post operatively anatomic and esthetic results were good, without recurrences.

A rare case of frontal sinus osteoma growing intracranially in a female of 38 is reported. The disease ran without any otorhinolaryngological or neurological symptoms until the sinus blunt injury followed by headaches resistant to analgetics and other neurological signs. Computed tomography discovered osteoma involving the cerebral cranium and pneumocephalus in the right cranial fossa. Management of patients with paranasal sinuses should account for possible intracranial complications and CT control of the tumor growth is very much desired.

A 28-year-old woman presented with 6 months of intractable left frontal headache that was proved to be due to an intracranial lesion. After successful surgical removal, it was found to be an intracerebral osteoma without a dural attachment. The literature of intracerebral osteoma is reviewed.

The imaging features of benign osseous lesions of the bone are often characteristic and suggestive of a specific diagnosis. This is particularly true for skeletal benign bone-forming lesions such as enostosis, osteoma, osteoid osteoma and osteoblastoma. Enostosis or bone island is an incidental finding in the axial skeleton (pelvis, spine, ribs) of asymptomatic patients; it appears as a small (0.2-2 cm) round to oval sclerotic area with irregular, radiating ('thorny') spicules peripherally. Osteoma is a benign slow-growth tumor and usually an incidental finding in cranial sinuses, vault and mandible, and presenting as a homogeneous, sharply defined bone mass arising from bone surface; its signs and symptoms are rare and depend on the tumor size and location--e.g. sinusitis, headache, exophthalmos, diplopia. Osteoid osteoma is a painful highly vascularized benign tumor usually affecting the long bone diaphysis cortex of young patients; it generally appears as a small radiolucent nidus with or without central calcification and surrounding bone sclerosis on radiographs, and as a 'hot' spot on scintigraphy. CT is the method of choice for the definite location of the nidus especially in sites of complex anatomy, such as the spine, pelvis and hindfoot. Osteoblastoma is a rare tumor, histologically similar to osteoid osteoma but with a significantly different clinical potential because of the possibilities of postoperative recurrence, of its locally aggressive behavior or, rarer still, malignant transformation; the spine and long bones are affected in more than half the cases. Its radiologic appearance is not always distinctive and usually characterized by a lytic lesion with varying bone production and expansile behavior; CT and MRI are required for the diagnosis of spinal osteoblastomas. When a bone-producing tumor or tumor-like lesion is suspected but no specific diagnosis can be made, the knowledge of the range of the imaging findings of these lesions will allow a suitably ordered differential diagnosis. Radiography is the single most effective imaging method in this respect. CT is required for the tumors in complex anatomical sites, such as the spine, pelvis and hindfoot, as well as for the optimal assessment of the tumor matrix. MRI is specifically required to study the lesion effect on the spinal canal.
