Pediatric temporal fistula: Report of three cases

Figure 2 Computed tomography and three-dimensional imaging of the left frontotemporal. A: Computed tomography (CT) images. At the left frontotemporal junction, an irregular low-density mass with a size of about 15.28 mm × 5.64 mm × 14.16 mm was observed subcutaneously, and the density was uneven. The CT value was about 32 HU. After enhancement, the edge of the lesion was enhanced, and the CT value was about 61 HU in the arterial phase and 86 HU in the venous phase. The local tubular foci extended to the deep left frontal temporal bone, which seemed to penetrate the inner plate of the skull. Osteosclerosis was visible in the marginal bone. The boundary between the lesion and adjacent muscles was not clear, and local skin become thick with abnormal enhancement changes; B: Three-dimensional imaging. Orange arrows indicate the fistula.
