Recurrent pheochromocytoma in pregnancy, even after bilateral adrenalectomy, can be managed successfully. Close maternal and fetal surveillance is key to achieving good outcomes.

Area of Science:

  • Endocrinology
  • Obstetrics
  • Oncology

Background:

  • Pheochromocytoma recurrence is common and poses significant risks during pregnancy.
  • Adrenalectomy is the standard treatment; successful pregnancies post-bilateral adrenalectomy are documented.
  • Recurrent pheochromocytoma in pregnancy presents high risks for both mother and fetus.

Observation:

  • A primigravid woman with a history of bilateral adrenalectomy for pheochromocytoma was monitored throughout her pregnancy for tumor recurrence.
  • Signs of recurrence at 18 weeks' gestation included maternal tachycardia, elevated urinary catecholamines, and rising hematocrit levels.
  • Medical management and antenatal testing were initiated, with labor induced at 36 weeks due to decreased amniotic fluid.

Findings:

  • Recurrent pheochromocytoma was identified via tachycardia, elevated catecholamines, and hemoconcentration (rising hematocrit).

  • Hemoconcentration, alongside increased catecholamines, can lead to uteroplacental insufficiency.
  • A healthy infant was delivered vaginally at 36 weeks' gestation, with no postpartum maternal complications.

    • Implications:

    • Intense surveillance and timely medical intervention are crucial for managing recurrent pheochromocytoma in pregnancy.
    • Early detection of hemoconcentration and elevated catecholamines can help prevent severe maternal and fetal complications.
    • This case highlights the possibility of successful pregnancy outcomes with vigilant management of recurrent pheochromocytoma post-adrenalectomy.
