In a remarkable medical case highlighting the importance of early neurological evaluation during pregnancy, a 29-year-old woman carrying a 14-week precious pregnancy after two previous miscarriages was successfully treated for an exceptionally rare 1-in-9-million pituitary inflammatory disorder after her symptoms were initially mistaken for migraine.
The patient arrived with severe headache, persistent vomiting, progressive blurred vision, and worsening neurological distress, symptoms commonly linked to pregnancy-related migraines. Given her previous history of migraine attacks, she was initially treated conservatively at another facility. However, her condition continued to deteriorate despite medication, prompting specialists to suspect a more serious neurological cause.
After extensive counselling on imaging safety during pregnancy, doctors performed an MRI brain scan, which identified a sellar-suprasellar pituitary mass measuring several millimeters, compressing the optic chiasm, the structure responsible for transmitting visual information from the eyes to the brain. The compression had already caused bitemporal hemianopia, a visual defect resulting in loss of peripheral vision on both sides.
Doctors initially suspected pituitary apoplexy, a rare endocrine emergency affecting approximately 1 in 10,000 people globally, often caused by sudden bleeding or enlargement of the pituitary gland. Medical literature shows that delayed intervention in such cases can result in permanent blindness, severe hormonal collapse, adrenal crisis, and maternal-fetal mortality risks exceeding 20 percent in severe untreated cases.
The complexity of this case was amplified by pregnancy. Research indicates that non-obstetric surgeries during pregnancy account for only 0.75 to 2 percent of all pregnancies worldwide, while neurosurgical procedures during gestation are even rarer. The second trimester, between 13 and 28 weeks, is considered the safest surgical window, as fetal organ formation is complete and uterine size allows safer anesthesia and positioning.
A multidisciplinary team of Obstetrics, Endocrinology, Neurosurgery, and Ophthalmology specialists was assembled immediately. The patient was stabilised with high-dose corticosteroids and hormone replacement therapy before surgery.
Dr. Mridula Devi A, Consultant in Obstetrics and Gynaecology, said, “Managing neurosurgical emergencies during pregnancy demands precision and coordination. Timely diagnosis and close fetal monitoring were essential to ensuring both maternal recovery and pregnancy continuation.”

Due to rapidly worsening vision, surgeons performed an endoscopic endonasal transsphenoidal decompression surgery, a minimally invasive skull-base procedure performed through the nasal cavity using neuro-navigation guidance. The surgery was completed successfully with continuous fetal heart monitoring and maternal vital surveillance throughout the procedure.
Postoperatively, the patient developed diabetes insipidus, a recognised complication occurring in 10–30 percent of pituitary surgeries, which was identified early and controlled medically. Her vision improved significantly within days, and both maternal and fetal conditions remained stable.
Unexpectedly, final histopathology ruled out pituitary adenoma and instead confirmed necrotizing granulomatous hypophysitis, an inflammatory pituitary disease so rare that it is estimated to occur in just 1 in 9 million individuals worldwide.
The patient remains on long-term hormone replacement therapy and continues regular neurological and obstetric follow-up. Her pregnancy is progressing normally, and doctors plan reassessment after delivery.
The case underscores the critical need for timely neuroimaging, multidisciplinary coordination, and personalised maternal counselling, particularly when neurological symptoms during pregnancy deviate from typical migraine patterns.
