Coronal HRCT temporal (soft tissue algorithm)This CT scan depicts an opacified left middle ear and mastoid antrum with the appearance of an ovoid lesion occupying the left parapharyngeal space (arrowheads) in contrast with the normal right parapharyngeal space. The lesion is heterogeneous with predominantly fatty attenuation centrally, and a laminated soft tissue capsule. Curvilinear soft tissue traversing the fatty central matrix could represent septations. The floor of the left middle ear appears absent (arrow); this is due to the widening of the osseous Eustachian tube seen on axial images (Figure 3). The soft tissue capsule showed minimal enhancement post iodinated contrast administration (not shown)HRCT: high-resolution computed tomography
