A 24 year old female presented to her general practitioner with general malaise. She had a genetic diagnosis of hereditary non-polyposis colorectal cancer (Lynch syndrome), with no colonic lesions detected on screening. Routine biochemistry revealed a potassium of 2.1mmol/l, requiring admission for urgent investigation and intravenous replacement. Further clinical assessment found a past history of severe acute thoracic back pain (3-months prior to presentation), weight gain and muscle weakness. Clinical examination revealed clear Cushings syndrome, including: thinning of the skin, Cushingoid facies, proximal muscle weakness and hypertension (>180/110mmHg). Her inpatient investigations revealed a basal cortisol of >1,000nmol/l, which was not suppressed with an overnight dexamethasone test, and a fully suppressed ACTH. A thoracic spinal x-ray also diagnosed vertebral fractures. In addition to potassium replacement, upon confirmation of hypercortisolaemia the patient was treated with metyrapone, co-trimoxazole (prophylactic dose), antihypertensives and chemical thromboprophylaxis. The patient underwent multiple imaging modalities of the body, including MRI, CT and PET. She was diagnosed with a left adrenocortical cancer (~8 cm). Her metyrapone was titrated to attempt to control her hypercortisolaemia and she was referred for surgery.
