Figure 2: (a-d) Axial contrast enhanced computed tomographic sections in caudocranial direction showing the course of the sinus tract bilaterally. Tract on the right side was well-opacified with contrast and extended from external opening to just superior to hyoid bone (white arrow). On the left side, a small collection was seen beneath the skin surface (curved arrow in a) with unopacified hypodense tract extending superiorly from it (blue arrow)
