I believe A = capsule

Which then means

B= glomerulosa -> aldosterone

C= fasiculata -> cortisol

D= reticularis -> androgens

E = adrenal medulla -> catecholeamines

Patient has pheochromocytoma -> increased catecholamines -> increased BP, headache, perspiration, palpitations + presence of catecholeamine breakdown (metanephrines)

Pheochromocytomas are tumors of the adrenal medulla, derived from chromaffin cells of the neural crest. In regards to the image, A is possibly the capsule allowing E to be the adrenal medulla? Here are some web images, sorry I can't solve this mystery, zoinks.
