Низкий уровень кортизола выявил причину психоза у студента: редкий случай апоплексии гипофиза

One Abnormal Lab Value Turned a Student's First Psychotic Episode into a Hunt Inside a Pea-Sized Gland She was a university student with no psychiatric history and no family history of mental illness. Over three months, her grandiose ideas hardened into fixed delusions: that others envied her, that she had received a secret marriage proposal, that she was seriously ill. She stopped caring for herself, stopped sleeping, and stopped functioning academically. Then a routine blood test came back showing low cortisol, and the case turned into something else. The report, published August 24 in The Egyptian Journal of Neurology, Psychiatry and Neurosurgery by clinicians in Muscat, Oman, describes psychosis as the dominant presentation of what the authors classify as suspected pituitary apoplexy. That word, suspected, is doing real work. One Abnormal Number in an Otherwise Normal Panel Her mental status examination found a euphoric mood, grandiose, paranoid, and somatic delusions, and poor insight. Notably, she had no hallucinations. Attention, concentration, memory, and orientation were all intact. Endocrine testing was almost entirely unremarkable. Prolactin, thyroid function, luteinizing hormone, follicle-stimulating hormone, and estradiol all came back normal. Only morning cortisol was low. A dynamic test to confirm adrenal insufficiency was planned but could not be completed because she was too agitated to cooperate. A brain CT showed an enlarged pituitary gland containing hyperdense material, a pattern that raised suspicion for bleeding into the gland. Ophthalmological assessment then found a visual field defect despite normal visual acuity, consistent with pressure on the optic chiasm. She reported no headache, nausea, or visual complaints. That absence is what makes the case unusual. Pituitary apoplexy classically announces itself with abrupt severe headache, visual loss, eye movement problems, and hormonal failure, according to a StatPearls review maintained through the National Library of Medicine, which also describes acute adrenal insufficiency as the most immediate threat to life. This patient had almost none of that. What the Imaging Could and Could Not Confirm MRI is the gold standard for evaluating the pituitary, but it was not performed during her acute admission because she was unable to cooperate with the scan. That gap shapes the entire report. When an outpatient MRI was eventually obtained, it showed a well-defined lesion centered in the pars intermedia that the radiologists suggested might represent a Rathke cleft cyst, a benign remnant of embryonic development, rather than a hemorrhagic pituitary tumor. The authors do not paper over this. They write that the case is best interpreted as suspected pituitary apoplexy, acknowledging the limitations of CT in detecting small hemorrhages and distinguishing pituitary bleeding from other lesions in the same region. The initial CT appearance, the visual field defect, and the low cortisol all pointed in one direction. Definitive radiological confirmation never arrived. Treatment proceeded anyway. She received intravenous hydrocortisone, and her irritability dropped by roughly half within 24 hours, though the delusions persisted. Clonazepam and olanzapine were added for agitation and insomnia. She was discharged after about a week on oral hydrocortisone with endocrine and psychiatric follow-up. Over subsequent months, her psychotic symptoms resolved. Olanzapine at higher doses caused stiffness, slowed gait, and sedation, prompting a switch to cariprazine. At the last review, she was stable, euthymic, and planning to resume her studies. Why Missing Cortisol Can Look Like Psychiatric Illness Cortisol is not a peripheral player in brain function. The National Institute of Diabetes and Digestive and Kidney Diseases describes it as essential to life, helping control blood pressure, blood sugar, inflammation, and metabolism. When it runs short, the agency notes that the result can include fatigue, muscle weakness, loss of appetite, and weight loss. The authors propose three overlapping mechanisms for the psychiatric picture: disrupted feedback along the hypothalamic-pituitary-adrenal axis, impaired function in limbic structures such as the hippocampus and amygdala that cortisol helps regulate, and metabolic and inflammatory changes that accompany cortisol deficiency. They note that psychosis has also been described in Addison's disease, the primary form of adrenal insufficiency, which they treat as supporting evidence that low cortisol itself can drive symptoms. Their literature search, covering case reports published between 2000 and 2025, turned up 78 candidate articles and only seven that met the inclusion criteria. That number is the point. Psychosis as the leading feature of pituitary apoplexy is rare enough that most clinicians will never see it. Secondary adrenal insufficiency, the form that begins in the pituitary rather than the adrenal glands, is itself uncommon. NIDDK puts it at roughly 150 to 280 people per million in developed countries. What This Means for First-Episode Psychosis The recommendation the authors make is modest and testable: check an early morning cortisol in patients presenting with first-episode psychosis, and consider neuroimaging with attention to the sellar region when the presentation is atypical. They flag several features in this patient as potential red flags for an organic cause: the absence of hallucinations, unusual somatic delusions, and rapid functional decline. Adrenal insufficiency, they argue, is a treatable cause of psychosis when identified promptly. Two cautions belong alongside that. First, this is one patient with an incompletely confirmed diagnosis, and single case reports cannot establish how often organic causes underlie new psychosis or whether routine cortisol testing would change outcomes. Second, the overwhelming majority of first-episode psychosis is not caused by a pituitary problem. In the United States, the National Institute of Mental Health describes coordinated specialty care, a team-based approach combining therapy, medication, and support for work or school, as the standard of care for early psychosis. Nothing in this report argues for delaying that while hunting a rare endocrine explanation. She also received antipsychotic medication throughout, alongside hormone replacement. The authors credit both. Untangling which produced which improvement is not possible from a single case, and they do not claim otherwise. Anyone experiencing a first episode of psychosis, or supporting someone who is, should seek evaluation from qualified clinicians rather than pursuing specific tests based on a published case. Key Questions Answered What is pituitary apoplexy? It is sudden bleeding into or loss of blood supply to the pituitary gland, usually involving a pre-existing tumor. It is treated as a neurosurgical and endocrine emergency and typically presents with abrupt headache, visual problems, and hormonal failure. Why is this case labeled suspected rather than confirmed? MRI, the gold standard for pituitary imaging, was not performed during the acute admission because the patient was unable to cooperate. A later MRI suggested a possible Rathke cleft cyst instead of hemorrhage, so the diagnosis was never definitively confirmed. How common is psychosis as the first sign? Very rare. The authors' review of case reports from 2000 to 2025 screened 78 articles and identified only seven meeting their criteria, which is why the condition is easily missed in psychiatric settings. What made doctors look beyond psychiatry? An incidentally low serum cortisol on initial laboratory testing. Follow-up imaging then showed an enlarged pituitary, and an eye examination found a visual field defect that the patient had not noticed. Did the hormone treatment fix the psychosis? Not by itself. Intravenous hydrocortisone reduced her irritability by roughly half within 24 hours, but the delusions persisted, and antipsychotic medication was added. Her symptoms resolved over subsequent months on combined treatment. Should everyone with new psychosis get a cortisol test? The authors recommend basic endocrine evaluation, including morning cortisol, in first-episode psychosis, but that is a suggestion from a single case report, not established guidance. Decisions about testing belong with treating clinicians. Published by Medicaldaily.com
