Plain-English summary

A cat with suspected insulin resistance was diagnosed with pituitary dependent hyperadrenocorticism, a condition where the pituitary gland produces too much hormone, leading to various health issues. Tests including an ACTH stimulation test and a dexamethasone suppression test confirmed the diagnosis, and a tissue examination showed a tumor in the pituitary gland. Treatment options for this condition can vary, and it's important for pet owners to discuss the best approach with their veterinarian.
