Abdominal neurenteric cyst

Figure 1 Axial CT scan showing a large bilocular cyst in the region of the body and tail of the pancreas (A) and a second more caudal axial CT slice (B).

Figure 2 Histological slides showing the full spectrum of epithelia within the cyst lining.

Figure 3 Histological slide showing elements of an abortive muscular layer and focal irregular neuronal hyperplasia in the cyst wall (A) and a more irregular configuration of the cyst with various ganglio-neuronal elements including Paccinian corpuscles (B).

Figure 4 Histological slides showing more specialized epithelia with consistent immunoreactivity to anti-cytokeratin 7 (A), anti-cytokeratin 18 (B), CA19-9 (C), and mixed abundant neuro-ganglionic/neuro-glial elements that were immunohistochemically verified (immunostaining is with the monoclonal antibody to glial fibrillar acidic protein) (D).
