- Fig 1.
Schematics and radiographs demonstrating the different grades of extent of LEA infiltration through the porcine rete. A and E, Grade I, <50% infiltration of the ipsilateral rete. B and F, Grade II, >50% but <100% infiltration of the ipsilateral rete. C and G, Grade III, complete infiltration through the ipsilateral rete with <50% of the contralateral rete. D and H, Grade IV, complete infiltration through the ipsilateral and >50% of the contralateral rete.
- Fig 2.
Microscopic pathology of the rete mirabile. Three different specimens are shown as examples of grade 0, no filling (A); grade I, incomplete filling (B); and grade II, complete filling of the proximal rete (C). (Hematoxylin phloxine saffron stain; original magnification × 50.)
