Summary
A patient experienced a perioperative crisis mimicking malignant hyperthermia, later diagnosed as phaeochromocytoma. This case highlights diagnostic challenges and potential misdiagnosis risks in critical care.
Area of Science:
- Anesthesiology
- Endocrinology
- Critical Care Medicine
Background:
- Malignant hyperthermia and phaeochromocytoma share overlapping clinical presentations, including hypertension and tachycardia.
- Perioperative crises require accurate differential diagnosis to guide appropriate management.
Observation:
- A 52-year-old woman developed intraoperative hypertension, tachycardia, acidosis, and hypoxemia during cholecystectomy, initially suspected as malignant hyperthermia.
- The patient subsequently experienced severe cardiogenic pulmonary edema and ventricular fibrillation leading to cardiac arrest, requiring resuscitation.
- Postoperatively, a phaeochromocytoma was identified as the underlying cause.
Findings:
- The clinical presentation of malignant hyperthermia and phaeochromocytoma can be remarkably similar, leading to potential diagnostic confusion.
- Prompt recognition and treatment of the underlying phaeochromocytoma are crucial for patient outcomes.
Implications:
- This case underscores the importance of considering phaeochromocytoma in patients presenting with perioperative hypermetabolic crises.
- Misdiagnosis can lead to delayed or inappropriate treatment, potentially exacerbating a critical event.
- Enhanced diagnostic vigilance is necessary to differentiate between these conditions and ensure optimal patient care.
