This case report involves an adolescent primigravida at term who was admitted with urinary complaints to the labor and delivery unit of a medical center. Within an hour, she suddenly began screaming and complaining of severe pain running from her anterior pelvis through her vagina and up her spine. Three days of very challenging comanagement of the patient, with several recurrences of acute pain, followed. Differential diagnoses that could explain this patient's symptoms are reviewed and discussed. Difficult management issues, including the stress of clinical management in the face of unidentified disease processes, are addressed. Lacking a certain diagnosis even retrospectively, the authors request comments from readers.
