This woman’s misdiagnosed migraine is a nightmare case that’ll keep docs up at night
Vital Signs
Female
Age 52
Presents with migraine headaches
MRI of brain performed
Cerebral edema and brain lesions visualized
A 52-year-old woman arrived at the emergency department convinced her worsening migraines were to blame for her confusion and balance issues. She’d battled headaches for years and chalked up her recent symptoms to stress.
But what began as a seemingly routine migraine case quickly unraveled into a devastating example of how fear, misinformation, and delayed care can transform a curable condition into a terminal diagnosis.
Neurosurgeon Betsy Grunch, MD, shared details of this case on Instagram to drive home a message physicians know too well: Early screening saves lives—but only if patients trust it.

The patient came to the ED with severe headaches that had intensified over several weeks, accompanied by confusion and subtle behavioral changes.
Her family said she “wasn’t acting like herself.” Otherwise healthy, she had no history of trauma, infection, or cancer. She mentioned a history of migraines but no other major conditions.
When asked about her medical history, she hesitated—then admitted she had discovered a lump in her breast more than a year earlier. She never told her doctor. She’d seen viral posts warning that mammograms could cause cancer and was too afraid to schedule one.
The Tests
Her MRI told a different story. Contrast imaging revealed extensive cerebral edema and too-many-to-count enhancing lesions throughout the brain—many clustered in the cerebellum. To Dr. Grunch, the pattern suggested multifocal metastases.
A CT scan of the chest, abdomen, and pelvis confirmed it: a 3-cm irregular mass in the left breast, axillary adenopathy, pulmonary nodules, and multiple bony lesions. The differential was narrowing fast.
The Diagnosis
A core biopsy confirmed grade 3 infiltrating ductal carcinoma (IDC)—ER/PR-negative, HER2-positive—with metastases to the brain, lungs, and bone.
IDC is the most common form of breast cancer, accounting for 75–80% of invasive cases. It originates in the milk ducts and becomes “infiltrating” when malignant cells break through the duct wall into surrounding tissue, gaining access to lymphatic and vascular channels.
In this case, what began as a localized and potentially curable lesion had evolved into stage IV breast carcinoma with brain metastases—a transformation driven not by aggressive tumor biology alone, but by hesitation born of misinformation.
The Treatment
The patient was started on high-dose steroids to reduce cerebral edema, followed by whole-brain radiation therapy and HER2-targeted systemic chemotherapy. Despite these interventions, her prognosis was poor.
Dr. Grunch used the case to underscore a critical public health truth: “Mammograms do not cause breast cancer. But fear and misinformation about them absolutely cost lives.”
A standard screening mammogram delivers just 0.4 mSv of radiation—about the same exposure as a few cross-country flights or seven weeks of background radiation.
There is no evidence linking mammograms to breast cancer development. Yet their life-saving potential is well-documented: early-stage IDC has a >99% five-year survival rate, while metastatic disease involving the brain carries an average survival of 6–18 months.
Had the patient sought care when she first felt the lump, her course might have included a diagnostic mammogram, ultrasound-guided biopsy, lumpectomy, radiation, and adjuvant therapy—a dramatically different trajectory.
The Takeaway
The US Preventive Services Task Force recommends screening every one to two years starting at age 40 for women at average risk, with earlier screening for those with family history or genetic predispositions (e.g., BRCA1, BRCA2, PALB2).
As Dr. Grunch reminds her audience: “Misinformation kills ... Mammograms don’t cause cancer—they find it when it’s curable.”
For clinicians, this case reinforces the need to proactively debunk viral medical myths during patient encounters. In an age when social media shapes beliefs faster than evidence can catch up, myth correction has become not just good communication—but essential preventive care.
