“…The coexistence of different changes is typical of fibrous dysplasia but can result is problems regarding differential diagnosis on MRI and can resemble aggressive lesions. On T2w images, lesions can appear very hypointense or also extremely hyperintense depending on the relationship between fibrous tissue and bony matrix [27]. After contrast administration, enhancement with low signal intensity tends to be characteristic for these lesions but intense enhancement is also possible [1] (▶ Fig.…”

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.

“…All the sequences show a hypointense halo that corresponds to sclerotic margins. MRI is the modality of choice to demonstrate the internal structures of the lesion and evaluate disease extension, especially in cases due for surgical treatment 8 (Fig 9).…”

-Purpose:A variety of diseases affect the calvaria. They may be identified clinically as palpable masses or incidentally in radiologic examinations. There are many diagnostic possibilities, including congenital, neoplastic, inflammatory and traumatic lesions. The purpose of this study is to illustrate the main calvarial lesions through MR imaging, their signal intensity and extension to neighboring sites. Method: A retrospective analysis of 81 cases, from November 1996 to July 2001, was conducted. The examinations were performed on a 1.5 T equipment and each one of the cases was pathologically proven. Conclusão: A RM detecta precocemente as alterações que envolvem a medula óssea, bem como demonstra acuradamente o envolvimento dos tecidos adjacentes. Este método é fundamental na avaliação detalhada das lesões da calota craniana.

“…MR has variable presentation. Jee et all [4] in their study showed that fibrous dysplasia gives homogeneous hypo intensity on T1 weighted images throughout the lesion. On T2 weighted images MR images showed varying signal intensity, 62% in their study showed homogeneous hyper intensity and 38% showed relative homogeneous hyper intensity.…”

Unilateral maxillary swelling is a rare condition, however we being in tertiary care centre did see a large number of these cases. All patients presenting with unilateral maxillary seen during the last 3 years were included in this retrospective study and evaluated concerning histories, diagnostic and therapeutic approaches and achieved outcomes. A total of 31 patients were seen during this period. 27 of these were benign lesions and were subdivided as follows: odontogenic cystic lesions (11/ 27), fibro-osseous lesions (8/27), secondary to extensive allergic fungal sinusitis (5/27) and mucocele (2/27). The remaining five were malignant lesions, two each were squamous cell cancer and adenocarcinoma of the maxillary sinus, and one was rhabdomyosacroma. All patients received treatment with due merit of the underlying etiology. Understanding and recognizing key diagnostic features helps in appropriate management and reducing morbidity.
