Case 1: Girl, 2 years six months old, with nontender right submandibular mass. Axial contrast-enhanced CT scan shows medial displacement of right submandibular gland (S) by right submandibular adenopathy (A). Suppurative granulomatous material represented by low-density ring-enhancing subcutaneous mass (arrow) extending from adenopathy to skin. Minimal stranding of adjacent subcutaneous fat is present.
fig 2. Case 7: Four-year-old girl with masses in left preauricular and submandibular regions. Axial contrast-enhanced fat-suppressed T1-weighted, 700/16/2 (TR/TE/excitations), conventional spin-echo MR image, demonstrates low signal intensity lesion (arrow) with ring enhancement, which corresponded to purulent material at surgery. Mass extends from superficial surface of left intraparotid lymph node (short arrow) to skin. No stranding of the adjacent subcutaneous fat is present.
