ABSTR AC TBackground Although a wide range of processes along the neurocranium are of a benign nature, there are often difficulties in the differential diagnosis.Method In the review CT/MRI scans of the head were evaluated retrospectively regarding solitary lesions along the neurocranium. The majority of the lesions were histologically proven.Results The purpose of the review is to present typical pathologies of the neurocranium and provide a systematic overview based on 12 entities, their locations, prevalence and radiological characteristics.Conclusion Processes, which primarily originate from the neurocranium have to be differentiated from secondary processes infiltrating the neurocranium. For this important diagnostic feature, MRI is typically essential, while the definitive diagnosis is often made on the basis of the medical history and the typical appearance on computer tomography. Key Points▪ There are often difficulties in the precise differential diagnosis of solitary lesions along the neurocranium. Typical solitary pathologies of the neurocranium based on 12 entities were presented. Both magnetic resonance imaging and computed tomography are often essential for an exact differential diagnosis. Schlussfolgerung Unterschieden werden müssen Prozesse, die primär vom Neurokranium ausgehen, von sekundären Prozessen, die das Neurokranium infiltrieren. Für dieses wichtige diagnostische Merkmal ist die MRT meistens unverzichtbar, während die definitive Diagnose dann unter Berücksichti-gung der Anamnese mit dem typischen Erscheinungsbild in der CT häufig gestellt werden kann.

“…Primary intraosseous meningioma has been hypothesized to arise from arachnoid cell rests caught within extradural tissues during embryologic development (Azar-Kia et al, 1974;Lee et al, 1988;Arana et al, 1996;Lang et al, 2000). These lesions are usually observed near the suture lines (most commonly at the coronal or pterion sutures) (Ito et al, 1992).…”

Primary intraosseous calvarial meningiomas are very rare entities in recent times. We present the first case in antiquity of a primary intraosseous meningioma in the frontoparietal bone associated with the coronal suture, and discuss its pathology. The skull derives from southwestern Germany and is dated to the 12th-14th centuries AD. The lesion is interpreted as a solitary osteoblastic neoplasm with hyperostosis on the outside, and osteolysis and radial spiculation in the central part of the lesion with an area of irregularity along the inner table. In cases of solitary osteoblastic skull lesions the differential diagnosis comprises: fibrous dysplasia, osteoma, osteoblastic metastasis, Pagets disease and meningioma with sheet-like growth along the dural surface with marked hyperostosis (called meningioma en plaque). We believe that a differentiation between hyperostotic meningioma en plaque and intraosseous meningioma cannot be made in skulls from antiquity.

“…Hyperparathyroidism or multiple myeloma cause a more ‘salt and pepper’ pattern due to multiple lytic defects. A hyperostosing calvarial meningioma can show a hyperostosis or – more often – a mixed pattern [8]. In sarcomatous degeneration of a meningioma, pagetic calvarium or in the case of a superinfection of a benign tumor (e.g.…”

We report a 15-year-old boy who suffered from calvarial sclerosing osteomyelitis and presented with painful head swelling. X-rays of the skull revealed areas of irregular radiolucency. MR imaging and CT showed a well-demarcated intradiploic lesion with thickening of the skull extending from the frontal to the parietal calvarium with a low signal on T1-weighted images, strong but heterogeneous enhancement after gadolinium application and a mixed signal on T2-weighted images. Computer-navigated neurosurgery was planned, and the craniotomy defect was reconstructed by a preformed titanium implant. Sclerosing osteomyelitis of the calvarium has to be included in the differential diagnosis of osteolytic and sclerosing lesions of the skull coinciding with persistent swelling of the head.
