The Pathology of the Endocrine Pancreas in Diabetes

Diabetes mellitus represents some of the most common and severe scientific syn­ dromes in modern medication. because the finish of the 19th century, the endocrine pancreas has been implicated within the pathogenesis of this disorder. a number of pathologists of the 20 th century detected a number of lesions and mor­ phologic adjustments within the pancreatic islets of diabetic sufferers, however the patho­ physiologic foundation in their findings remained lengthy imprecise.

F G Figure 7. (D) Coronal CT section with bone window setting T J -CW (and high SI on T2 -CW images). They are consistent with mucous retention cysts. S em). A mass of heterogeneous SI is located in the sphenoid sinus and posterior ethmoid cells, with extension to the middle ethmoid cells, posterior nasal cavity, superior nasopharynx, tuberculum sellae, and planum sphenoidale. The mass elevates the dura and frontal lobe without invasion of brain substance. The irregular, high SI areas within the mass are compatible with retained thick mucous secretions and/or blood degradation products.

Through the level of mid sphenoid sinus and posterior orbits shows a partially calcified mass extending into the upper third of both nasal cavities. There is elevation of the planum sphenoidale on the right, as well as irregularity and partial loss of the medial posterior wall of the right orbit. Note also a retention cyst in the lower medial right antrum. S em). A midline mass of intermediate SI invades the ethmoid cells bilaterally, and the superior part of the nasal cavity, obliterating the upper middle turbinates.

Radiologic findings Plain X-ray films of the sella and optic foramina showed dense opacification of the sphenoid sinus and posterior ethmoidal cells, as well as a poorly demarcated optic strut of the right optic foramen. A CT scan, with axial (Figure 7 A) and coronal (Figure 7D) sections, showed a heavily calcified mass, predominantly on the right, involving the sphenoid and ethmoid sinuses, with bulging into the posterior orbits, optic canals, sella, and intracranial cavity at the planum sphenoidale.
