Pheochromocytoma after Cesarean Section

Area of Science:

• Endocrinology
• Oncology
• Obstetrics & Gynecology

Background:

• Pheochromocytoma, a rare catecholamine-producing tumor, presents diagnostic challenges.
• Clinical presentation can mimic common postpartum conditions, delaying diagnosis.

Observation:

• A 27-year-old postpartum woman presented with headache, confusion, nausea, vomiting, anxiety, and palpitations.
• Physical examination revealed fever, tachycardia, tachypnea, hypertension, and a thyroid nodule.
• Initial management focused on presumed pregnancy-induced hypertension.

Findings:

• Laboratory tests showed elevated levels of epinephrine, norepinephrine, metanephrine, normetanephrine, and vanillylmandelic acid in 24-hour urine.
• Abdominal computed tomography confirmed an adrenal mass.
• Diagnosis of pheochromocytoma was established based on clinical and paraclinical findings.

Implications:

• This case underscores the importance of considering pheochromocytoma in postpartum patients with unexplained hypertension and symptoms.
• Prompt diagnosis and appropriate treatment, including adrenalectomy, are vital for favorable outcomes.
• Increased awareness among clinicians can improve the detection rates of this rare tumor.
