What is Pituitary Apoplexy?

Pituitary apoplexy is an acute clinical condition that occurs as a result of sudden hemorrhage or infarction in a known or unknown pituitary adenoma. The mass effect produced by apoplexy causes visual loss and ophthalmoplegia by compressing the visual pathways and cranial nerves. Acute cortisol deficiency is directly associated with the risk of adrenal crisis.

Most cases harbor an underlying macroadenoma; triggers include anticoagulant therapy, surgery, radiotherapy, dynamic tests, and pregnancy.

For diagnosis, pituitary MRI (preferred) or CT imaging should be performed urgently. Management includes corticosteroids in all patients (to prevent adrenal crisis) and urgent surgical decompression in those with visual loss or altered consciousness.

Symptoms

Sudden severe headache ('worst headache of my life')
Blurred vision or sudden vision loss
Double vision and ocular muscle palsy
Nausea, vomiting, and neck stiffness
Altered consciousness and drowsiness
Hypotension and circulatory failure (adrenal crisis)

Risk Factors

Having a pituitary macroadenoma
Use of anticoagulants or antiplatelet drugs
Pregnancy
Surgery or general anesthesia
Bleeding disorders

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When sudden, severe headache and visual disturbance develop together (URGENT!)
  • When the above symptoms begin in a patient with a known pituitary tumor
  • If altered consciousness and hypotension are present

Treatment Methods

01
Emergency IV hydrocortisone 100 mg: started in all patients to prevent adrenal crisis
02
Neurosurgery consultation: urgent decompression in case of visual loss or altered consciousness
03
If vision is intact and consciousness clear: conservative monitoring possible (with cortisol replacement)
04
Comprehensive evaluation of pituitary function after surgery
05
Long-term hypopituitarism replacement (cortisol, thyroid, gonadal hormones, growth hormone)
06
Periodic recurrence monitoring with pituitary MRI

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
