Type II Robert's Uterus Presenting as Long-Standing Secondary Subfertility: Diagnosis Confirmed by Combined Laparoscopy and Hysteroscopy in a Bangladeshi Patient.

Robert's uterus is a rare congenital Müllerian duct anomaly characterized by an asymmetric septum dividing the uterine cavity into a communicating and a blind hemicavity despite a normal external contour. Although fewer than 200 cases have been reported globally, the incremental novelty of individual case reports lies in unique clinical presentation and diagnostic challenges rather than rarity alone. We report a case of Type II Robert's uterus in a 30-year-old Bangladeshi woman presenting with long-standing (12 years) secondary subfertility in the absence of classical symptoms such as dysmenorrhea or hematometra, which is uncommon. Initial hysterosalpingography suggested a unicornuate uterus with bilateral tubal obstruction. Advanced imaging modalities (MRI and 3D ultrasonography) were not performed due to limited availability and financial constraints, necessitating definitive evaluation by combined laparoscopy and hysteroscopy. This revealed a normal external uterine contour, an asymmetric septate uterus with a blind left hemicavity, right tubal patency, and unilateral tubal obstruction. This case highlights two key contributions: (1) the potential for prolonged asymptomatic secondary subfertility in Type II Robert's uterus, and (2) the diagnostic value of combined endoscopy in the absence of advanced imaging in low-resource settings. Early recognition is essential to avoid misdiagnosis and enable appropriate fertility-preserving management.
