Cushing's Disease
Understanding how symptoms present, as well as tolerability for surgery, can help shed light on treatment.
Living with Cushing’s disease
Cushing’s disease, although rare, significantly impacts the lives of patients who are diagnosed with this condition. These profiles highlight typical patient concerns, and illustrate common symptoms associated with the manifestation of Cushing’s disease.
Patient
Teresa
Age: 55 years old
Patient Insight
Teresa has expressed embarrassment about her appearance due to weight gain, excessive bruising, hair growth on her face, and sweating. She consistently feels agitated and reports that she is unable to relax.
Treatment Naïve
Teresa has not had surgery; no history of medical treatment for hypercortisolism.
Disease
Cushing’s disease (severe, treatment naïve)
Diagnosed
Within the last year, 11 mm pituitary adenoma confirmed with MRI
Surgery
Not eligible for surgery (physician judgement); tumor extends into the cavernous sinus
Signs and Symptoms
Teresa has several signs/symptoms associated with high cortisol levels:
- Weight gain (17 lbs. over 6 months without changing diet or lifestyle); dorsocervical and supraclavicular fat deposits; central obesity
- Osteoporosis
- Edema in lower legs and ankles; thinning skin; bruises easily
- Hirsutism
Relevant Laboratory Parameters
- Current cortisol status: Uncontrolled
- 24 h UFC: 5.8 × ULN and 6.1 × ULN
- LNSC: 2 × ULN
- ACTH: 2 × ULN
Consider management options to control cortisol levels and improve clinical manifestations of hypercortisolism.

Patient
Andrea
Age: 47 years old
Patient Insight
Medical therapy for hypercortisolism was initiated 1 week after surgery. After 6 months on treatment, cortisol levels have reduced but remain persistently uncontrolled. Andrea is also experiencing gastrointestinal side effects that impact his adherence to the prescribed medication.
Treatment
Andrea has not had surgery; no history of medical treatment for hypercortisolism.
Disease
Cushing’s disease (moderate, persistent following surgery)
Diagnosed
Recently diagnosed; BIPSS confirmed pituitary source of ACTH secretion; 4 mm pituitary adenoma identified by MRI
Surgery
Transsphenoidal surgery to remove pituitary tumor; however, cortisol levels remained high and medical therapy was initiated
Signs and Symptoms
Signs and symptoms of hypercortisolism were noted by Andrea for at least 3 years prior to diagnosis:
- Increased central obesity and weight gain
- Rounded face
- Muscle weakness in upper limbs
- Increased appearance of striae
- Hypertension (137/89 mmHg)
- Hypokalaemia
- Diabetes
Relevant Laboratory Parameters
- Current cortisol status: Uncontrolled
- 24 h UFC: 3.0 × ULN and 3.3 × ULN
- LNSC: 2 × ULN
- ACTH: 2 × ULN
- Potassium: 3.0 nmol/L (normal: 3.6–5.2 nmol/L)
- HbA1c: 7.1%
Per treatment guidelines, consider adjusting medical therapy to improve adherence, or repeat surgery. If cortisol control remains insufficient, explore radiation therapy options. Bilateral adrenalectomy is a last resort if cortisol remains uncontrolled.

Patient
Mario
Age: 55 years old
Patient Insight
Mario has commented that because of his muscle weakness and tiredness, he is unable to go about his daily life, including playing with his young grandchildren.
Treatment
Despite attempts to optimize medical therapy since his surgery 5 years ago, Mario’s cortisol levels have not been controlled, nor have they stabilized.
Disease
Cushing’s disease (mild, persistent following surgery)
Diagnosed
Diagnosed 5 years ago; BIPSS confirmed pituitary source of ACTH secretion; 8 mm pituitary adenoma confirmed with MRI
Surgery
Transsphenoidal surgery to remove pituitary tumor, but cortisol remained uncontrolled
Signs and Symptoms
Without a consistent reduction in cortisol, Mario has not experienced improvements in his symptoms and comorbidities:
- Hypertension (160/90 mmHg)
- Diabetes
- Increased central obesity with weight gain (24 lbs. since diagnosis)
- Increased appearance of striae
- Osteoporosis
- Muscle weakness in lower limbs
Relevant Laboratory Parameters
- Current cortisol status: Uncontrolled
- 24 h UFC: 1.6 × ULN and 1.3 × ULN
- LNSC: 4 × ULN
- ACTH: 3 × ULN
- HbA1c: 6.9%
Per treatment guidelines, consider repeat surgery, radiation, or adding/adjusting meds. Bilateral adrenalectomy is a last resort if cortisol remains uncontrolled.
Case details adapted from: Antonini et al. 2022; Castinetti et al. 2021; Clayton et al. 2022; Fookeerah & McLean 2021; Frara et al. 2022; Gadelha et al. 2022; Moyers & Tiemensma 2020; Pivonello et al. 2016; Kamińska M et al. 2023; Pivonello et al. 2020; Santos et al. 2019; Valassi et al. 2022; Varlamov et al. 2021.
ACTH, adrenocorticotropic hormone; BIPSS, bilateral inferior petrosal sinus sampling; HbA1c, glycated haemoglobin; LNSC, late-night salivary cortisol; MRI, magnetic resonance imaging; UFC, urinary free cortisol; ULN upper limit of normal.
