Aim
The aim of this review was to evaluate the efficacy of magnetic resonance imaging (MRI) in determining appendicitis
during pregnancy.
Methods
We retrospectively reviewed the clinical course for all pregnant patients with suspected appendicitis from 2013-2018.
We evaluated the efficacy of MRI and Alvarado scoring and its impact on management.
Results
Twenty-nine pregnant patients with suspected appendicitis had an MRI. The majority (90%, n=26/29) had normal
diagnostics with two patients (10.3%) having findings consistent with acute appendicitis. Two other patients proceeded
to laparoscopy, one with an inconclusive MRI, and one patient with clinical appendicitis. We found no accurate
correlation between pregnancy and Alvarado scoring.
Conclusion
MRI is a safe adjunct in accurately diagnosing appendicitis in pregnancy. Its routine use could help reduce rates of
negative appendectomies and the potential risk to maternal and fetal health.
