Acromegaly After Surgery: Which Medical Therapy Fits a Borderline Glucose Tolerance

A single patient, six months past debulking surgery for a GH-secreting macroadenoma, with IGF-1 still elevated and a fasting glucose that is quietly drifting the wrong way. The disagreement is which of three real medical options actually fits a body that surgery has only partly fixed.

Case 0001
EndocrinologyPituitary
Trading the Injection for a Pill: Switching Acromegaly Control to Oral Paltusotine

A single patient, biochemically controlled for three years on monthly injectable octreotide, now asking about the newly approved oral alternative. The disagreement isn't about whether paltusotine works — it's about whether "already controlled" is a reason to leave well enough alone.

Case 0002

Three Years Normal on Cabergoline: Is a Residual Shadow Reason Enough to Keep Treating

A single patient, three years into normal prolactin on cabergoline, asking to stop. The disagreement isn't about whether withdrawal is ever reasonable — it's about whether a residual sliver still visible on her MRI is the specific fact that should keep her on the drug longer than the guideline's own general timeline suggests.

Case 0003
EndocrinologyPituitary
Cabergoline at the Ceiling: How Much Dose Is Worth the Heart Valve Question

A single patient, incompletely controlled on cabergoline despite two years of dose escalation, now facing a further increase that would put her cumulative exposure into range where echocardiographic monitoring guidance actually changes. The disagreement is whether to keep pushing the dose or change strategy entirely.

Case 0004
EndocrinologyPituitary
An Adenoma That Isn't Doing Anything Yet: Surgery or Watching, in a Patient With No Symptoms

A single patient, an 18mm nonfunctioning pituitary adenoma found incidentally, with normal vision, normal hormones, and no complaints. The disagreement is whether to operate before anything goes wrong, or watch and wait for a reason to.

Case 0005
EndocrinologyPituitary
A TSH That Won't Suppress: Choosing Between an Analog and the Operating Room

A single patient, a rare TSH-secreting microadenoma, biochemically eligible for either a somatostatin analog or transsphenoidal surgery, and a strong personal preference for the one guidelines treat as second-line. The disagreement is how much that preference should move a decision usually made on surgical-candidacy grounds alone.

Case 0006
EndocrinologyPituitary
Fatigue, a Confirmed Deficiency, and a Benefit Nobody Can Fully Prove

A single patient, biochemically confirmed adult growth hormone deficiency after pituitary surgery, weighing whether to start replacement. The disagreement isn't about the diagnosis — it's about how much weight to put on a benefit the literature itself hasn't fully settled.

Case 0007
EndocrinologyPituitary
Dosing Levothyroxine With No TSH to Trust

A single patient, central hypothyroidism confirmed after pituitary surgery, started on levothyroxine with no reliable TSH feedback to titrate against. The disagreement is where in the normal free T4 range the dose should actually land.

Case 0008
EndocrinologyPituitary
Replacing Cortisol Without a Second Hormone to Balance It

A single patient, confirmed ACTH deficiency after pituitary surgery, started on hydrocortisone with an intact renin-angiotensin system that makes her replacement genuinely different from primary adrenal insufficiency, not just a smaller version of it. The disagreement is how much smaller the dose should actually be.

Case 0009
EndocrinologyPituitary
He Wants Testosterone Fixed and a Baby Both — Only One Drug Does Both

A single patient, hypogonadotropic hypogonadism confirmed after pituitary surgery, wanting both symptom relief and a chance at fathering a child in the next year. The disagreement is whether the conventional first-line treatment is actually first-line for him at all.

Case 0010
EndocrinologyPituitary
His Insulin Doses Were Set for a Pituitary That No Longer Works the Same Way

A single patient, longstanding type 2 diabetes on a stable insulin regimen, now three weeks out from pituitary surgery that has left him GH- and cortisol-deficient. The disagreement is how far to cut his insulin before his numbers actually prove he needs it cut.

Case 0011
EndocrinologyPituitary
Three Phases in Two Weeks: Timing Desmopressin Against a Response That Keeps Changing

A single patient, two days out from pituitary stalk manipulation during surgery, now producing four liters of dilute urine a day. The disagreement is whether to start scheduled desmopressin now or dose only as symptoms demand, given what the same injury reliably does one week from now.

Case 0012
EndocrinologyPituitary
Twelve Years Stable on Desmopressin — and Quietly Trending Toward Low Sodium

A single patient, twelve years into permanent central DI after childhood cancer treatment, on a stable desmopressin dose with a sodium that has crept downward over the past two years. The disagreement is whether tighter dosing or a planned weekly gap in coverage is the safer long-term strategy.

Case 0013
EndocrinologyPituitary
A Sudden Headache, a Bleeding Adenoma, and a Visual Field That Hasn't Gotten Worse Yet

A single patient, hours into a sudden severe headache from a bleeding pituitary macroadenoma, with a real but stable visual field deficit and no reduced consciousness. The disagreement is whether stable is good enough to avoid the operating room tonight.

Case 0014
EndocrinologyPituitary
An Immunotherapy Side Effect That Won't Reverse, in a Drug She Needs to Keep Taking

A single patient, three months into combination checkpoint-inhibitor therapy for melanoma, now hypophysitis-confirmed with new adrenal and thyroid axis failure. The disagreement is how to sequence replacement and whether her cancer treatment needs to pause for any of it.

Case 0015
EndocrinologyPituitary
A Pituitary Mass That Isn't a Tumor: Steroids or a Closer Look First

A single patient, six weeks postpartum, with new headache, mild visual symptoms, and a pituitary mass that could be lymphocytic hypophysitis, IgG4-related disease, or an entirely unrelated nonfunctioning adenoma. The disagreement is whether to treat empirically or push for tissue first.

Case 0016
EndocrinologyPituitary
A Corticotroph Tumor That Keeps Coming Back: How Early to Reach for Chemotherapy

A single patient, on his third recurrence of a silent corticotroph adenoma despite two surgeries and radiotherapy, with imaging showing renewed growth. The disagreement is whether to try a third surgery first or move to temozolomide now, earlier than its traditional place in the sequence.

Case 0017
EndocrinologyPituitary
A Positive Pregnancy Test and a Question About the Pill She's Been Taking For It

A single patient, newly pregnant, on cabergoline for a macroprolactinoma close enough to the optic chiasm that standard discontinuation advice may not apply cleanly to her. The disagreement is whether to follow the usual rule or make an explicit exception.

Case 0018
EndocrinologyPituitary
An Empty-Looking Sella and Labs That Are Almost, But Not Quite, Normal

A single patient, an incidentally found empty sella with two borderline hormone axes, neither clearly failed nor clearly normal. The disagreement is whether borderline results in a structurally abnormal gland should be treated as deficiency now or watched until they resolve into a clearer answer.

Case 0019
EndocrinologyPituitary
Weight That Won't Respond to Willpower: Two Real Drugs for a Hunger the Surgery Left Behind

A single patient, two years past craniopharyngioma resection, with severe hyperphagia-driven obesity that hasn't responded to any lifestyle intervention. The disagreement is which of two real pharmacologic options — one repurposed, one built specifically for this problem — fits her mechanism better.

Case 0020
EndocrinologyPituitary
Better Tumor Control Would Cost Him His Glucose Control

A single patient, acromegaly inadequately controlled on first-generation somatostatin analog therapy, with established type 2 diabetes already imperfectly managed. The disagreement is whether switching to a more effective agent is worth its well-documented cost to his glucose control, and what to do about that cost if it isn't avoidable.

Case 0021
EndocrinologyPituitary
The Same Low Sodium, Two Opposite Treatments, and a Volume Exam That Has to Break the Tie

A single patient, five days out from suprasellar tumor resection, with hyponatremia and labs that fit both cerebral salt wasting and SIADH almost equally well. The disagreement is which one she actually has, since treating one as if it were the other risks real harm.

Case 0022
EndocrinologyPituitary
Diagnosed Two Years After the Delivery That Caused It

A single patient, two years past a postpartum hemorrhage severe enough to require transfusion, now presenting with a hormonal picture consistent with Sheehan syndrome. The disagreement is whether to complete full dynamic testing before treating, or start replacement now and test around it.
