  ABSTRACT: Background: A genital outflow tract obstruction is an uncommon cause of primary amenorrhea. If ovulation occurs, menstrual bleeding is prevented. Patients typically present with abdominal/pelvic pain due to hematocolpos. Absence of significant hematocolpos could indicate a secondary source of primary amenorrhea and be challenging to the clinical diagnosis. Case: 17 year-old patient with primary amenorrhea, appropriate Tanner staging secondary sex characteristics, and transverse vaginal septum presents with virtual absence of hematocolpos. After vaginal septum resection, the patient began menstruating, although only evidenced by two cycles of vaginal spotting. Conclusion: Significant hematocolpos is an expected sequella of distal outlet obstruction when collated with secondary sexual characteristics. Absence of such along with suboptimal return of menstruation reflects pathophysiology which may be attributed to a coexistent disorder of the hypothalamus or higher central nervous system function.
