primary dysmenorrhea due to mullerian duct anomaly . a diagnostic challenge in radiology

rabeea khan, Raisa Altaf Malik, bushra rehan, Mahum Zaidi


Mullerian duct dysgenesis results in various congenital anomalies including
unicornuate uterus with a rudimentary functional horn. This is a rare congenital
anomaly with a frequency of 1/100,000 (1) . However the true incidence and imaging
findings are largely undiscussed as according to studies only symptomatic cases are
reported (4) . Unicornuate uterus has an impact on the fertility of young females. Most
commonly presenting with dysmenorrhea, dyspareunia, endometriosis,
hematometra, UTI in severe cases torsion of the rudimentary horn (2) . Keeping in
view the anatomical variations of unicornuate uterus, the various symptoms
associated with it and fewer literature on this topic we present the imaging findings of
a young female who presented to the emergency department with severe lower
abdominal pain and a palpable mass. On imaging she had a unicornuate uterus with
a non-communicating functional rudimentary horn.
