Objective :

Cushing’s disease (CD) is the most common cause of endogenous cortisol excess. The magnitude of cortisol excess is associated with severity of disease. We present a case of CD without classical phenotype despite high cortisol, posing a diagnostic challenge.

Methods : NA

Results : NA

Discussion :

A 60-year-old female with vascular dementia was hospitalized for symptomatic anemia. Three months before this hospitalization she was diagnosed with type 2 diabetes, deep venous thrombosis (DVT), pulmonary embolism and non-healing wound over right ankle. Physical exam was remarkable for multiple ecchymoses on extremities, periorbital edema and hypertension. No evidence of moon facies, supraclavicular fat pad, striae or obesity. Hospital course was complicated by retroperitoneal hematoma. Discontinuation of anticoagulant led to new DVT requiring IVC filter. CT abdomen showed an incidental finding of L1 and L2 compression fractures. Refractory hypokalemia was notable. This in the context of hypercoagulable state, compression fracture and variable insulin requirements raised suspicion of cortisol excess.
Testing indicated ACTH-dependent hypercortisolism [random cortisol 122.2 ug/dl, ACTH 154.2pg/ml, loss of circadian rhythm and failure of low-dose dexamethasone suppression test (DST) with resultant cortisol of 111.6 and 151.1 ug/dl]. A high-dose DST showed a decline in cortisol to 38.5 ug/dl and elevated ACTH 67.5pg/ml. CT chest/abdomen/pelvis were negative. CRH stimulation test demonstrated a rise in ACTH (84.9 to 366 and 75.7pg/ml at 10 and 25 minutes). MRI brain showed no pituitary enlargement. Inferior petrosal venous sinus sampling (IPSS) revealed lateralization to the right. Transsphenoidal hypophysectomy was scheduled. While awaiting surgery, patient developed pneumonia. Her clinical status deteriorated and family decided on comfort care.
Initially, ectopic hypercortisolism was suspected given our patient’s age and rapid onset of symptoms but pan-CT was negative. This patient had an acute, severe and rapidly progressing clinical presentation with multiple metabolic consequences in the absence of a typical clinical phenotype. Adequate cortisol suppression was observed with high-dose DST. An unremarkable pituitary MRI added to the clinical dilemma. It is noteworthy that 40% of CD patients have no visible tumor on standard MRI. CRH stimulation and bilateral IPSS confirmed the diagnosis.


Conclusion :

Typically CD is considered an indolent disease compared to Cushing's syndrome due to ectopic ACTH secretion, clinical distinction is not always easy and rapidly progressing Cushing's disease results in significant morbidity and mortality without treatment.

I graduated from SMIMER (Surat Municipal Institute of Medical Education and Research) from Surat, India. I did my Internal Medicine residency training from Aurora Health Care, Milwaukee, WI (2014-2017). I was delighted to accept the position of a Chief resident at Aurora Health Care which helped to enhance my mentorship skills, time management and leadership skills. I was fortunate to start my fellowship in Endocrinology at SUNY Upstate Medical University in July 2018.
I strongly believe in Evidence based medicine and was involved in quality improvement project and committee during residency training. I also got opportunity to do poster presentation at American Geriatric Society Annual meeting (May, 2016) and Endocrine Society (March, 2018) as well as an oral presentation at American College of Physician (September,2015). I also wrote a book chapter on thyroid disease in the elderly which was published in "Encyclopedia for the Elderly".
As an Endocrine fellow, and ultimately a practicing internist, I plan on committing my life to the betterment of my patients, and the profession.
