Ultrasound of the abdomen usually reveals abnormal cystic or tubular, anechoic, serpiginous
vascular structures communicating between portal venous structures and the systemic circulation.
The imaging appearance at this stage is that of intracystic serpiginous
linear filling defects known as the "water-lily sign.
6 mm within the walls of respiratory bronchioles and adjacent alveoli; nodules, defined as fibrotic lesions up to 1 cm in size with round, irregular, or serpiginous
borders and containing dust-laden macrophages; and interstitial fibrosis, defined as diffuse or irregular fibrosis of alveolar septa and/or alveolar ducts.
Deviation of the nose to the left, absence of serpiginous
flow voids and intense enhancement were noted.
6) On MRI, the varix appears as a dilated, serpiginous
flow void in the epidural space.
The large nodules that are typically present may not be evident in the other less common histologic subtypes including occasional cases with smaller nodules, less circumscribed nodules, a serpiginous
pattern, or older lesions that have been infiltrated by T cells.
Compatible radiologic features are capsular enhancement with contrast, hypodense nodular areas, and low-density serpiginous
7 At the site of parasite entry (usually the feet), local skin reactions can occur, including inflammation, pruritus, edema, petechiae, and serpiginous
and urticarial tracts.
20) Neurogenic tumors usually enhance intensely with gadolinium diethylenetriamine-penta-acetic acid (DTPA), whereas glomus tumors have the characteristic serpiginous
areas of flow void (salt-and-pepper pattern) on MRI.

Likewise, a serpiginous
mass may be seen with connections to vascular structures.
Gross findings included numerous serpiginous
and coalescing, raised, ulcerated-to-papillary nodules on the dorsum anterior to the dorsal fin and extending to the mid-body (Figure 1, panel A).
