“…Several intrinsic channels, intrinsic fissures, and extrinsic sutures are often apparent on CT images and can mimic fractures (pseudofractures) (1). The major anatomic landmarks of the temporal bones are depicted on axial and coronal CT images (Figs 1-5) and are described in the following subsections.…”

From a clinical-radiologic standpoint, there are a limited number of structures and disease entities in the temporal bone with which one must be familiar in order to proficiently interpret a computed tomographic or magnetic resonance imaging study of the temporal bone. It is helpful to examine the region in an organized and systematic fashion, going through the same checklist of key structures each time. This is the first of a two-part review that provides a practical approach to understanding temporal bone anatomy, localizing a pathologic process with a focus on inflammatory and neoplastic processes, identifying pertinent positives and negatives, and formulating a differential diagnosis.

Skull base fractures comprise a relatively common finding among trauma patients. Before the widespread use of computed tomography (CT), these lesions used to be misdiagnosed. Currently, with improved imaging technology, diagnosis of skull base fractures is no longer cumbersome. On the other hand, cranial fractures involving the foramen spinosum are rarely described in the literature. In this present article, we report on a patient affected by head trauma, who suffered from a vault fracture towards the foramen spinosum and acute epidural hematoma (EH) due to middle meningeal artery injury. We further discuss the clinical consequences of foramen spinosum fracture. KEywoRds:Cranial epidural hematoma, Foramen spinosum, Middle meningeal artery, Skull base, Skull fracture ÖZKafa kaidesi kırıkları travma hastalarında nispeten sık görülen bir bulgudur. Bilgisayarlı tomografinin (BT) yaygın kullanımı öncesinde bu lezyonlara yanlış tanı konabiliyordu. Gelişmiş görüntüleme teknolojisiyle kafa kaidesi kırıklarına tanı koymak artık zor değildir. Öte yandan foramen spinosumu içeren kraniyal kırıklar literatürde nadiren tanımlanmıştır. Makalede kafa travması sonrasında foramen spinosuma doğru bir kafatası kırığı yaşayan ve orta meningeal arter yaralanması nedeniyle akut epidural hematom bulunan bir hasta sunuldu. Foramen spinosum kırığının klinik sonuçları üzerinde duruldu.

“…Some of the known clinical signs of BSF include racoon eye, rhinorrhoea, rhinorrhagia, anosmia, visual impairment, otorrhoea, otorrhagia, hearing loss, neurovascular injuries, Battle sign, phonation problems, vocal cord paralysis and/or aspiration. 4,6,14 It is important to note that if a CSF leak secondary to BSF is missed, it may lead to meningitis and, ultimately, death. 14–17 Identification of these clinical signs in the setting of trauma should always prompt the treating clinician to arrange for an urgent computed tomography (CT) scan of the brain or make a referral to a centre with CT scan facilities for early diagnosis and management so that complications can be avoided.…”

BackgroundBasal skull fractures (BSFs) have been reported to be a major cause of morbidity and mortality in the literature, particularly in young male patients. However, there are limited data available on the aetiology, prevalence and patterns of such observed in South Africa.ObjectivesTo evaluate the prevalence and pattern of BSF in head injury patients referred to Dr George Mukhari Academic Hospital, Gauteng, South Africa.MethodsPatients of all ages with head injuries were considered for the study, and those who met the inclusion criteria were scanned using a 128-slice multidetector helical computed tomography (CT) machine after obtaining consent. Data were prospectively obtained over a 6-month period, interpreted on an advanced workstation by two readers and statistically analysed.ResultsThe prevalence of BSF in this study was found to be 15.2%. The majority of patients (80.5%) were under 40 years old, with a male to female ratio of 3:1. The most common aetiology of BSF was assault, which accounted for 46% of cases. The middle cranial fossa was the most frequently fractured compartment, while the petrous bone was the most commonly fractured bone. There was a statistically significant association between head injury severity and BSF, and between the number of fracture lines and associated signs of BSF (p < 0.001). The sensitivity of clinical signs in predicting BSF was 31%, while specificity was 89.3% (p = 0.004).ConclusionThe prevalence and pattern of BSF found were consistent with data from previously published studies, although, dissimilarly, assault was found to be the most common aetiology in this study.
