Introduction: Phenotypically normal pre-pubertal girl presenting with only a little delay in onset of puberty and emotional lability is seldom thought to be suffering from a serious underlying congenital defect at the outset. Amongst different congenital causes for such presentation, Mayer-Rokitansky-Küster-Hauser syndrome is scarcely reported so far. This condition usually manifests with primary amenorrhoea and infertility in phenotypically and karyotypically normal 46, XX females. In the atypical form of this syndrome additional congenital malformations involving mostly renal and skeletal systems are noticed along with Mullerian dust dysgenesis.
Case description: A 12-year-old girl attended the adolescent clinic with complaints of generalised weakness, inadequate height gains and emotional lability. Initial clinical examination recorded genu valgus and absence of pubertal growth spurt. Subsequently, blood hormonal assay depicted hypergonadotropic hypogonadism state. Bilateral absence of gonads and Mullerian duct anomalies were detected further in an otherwise normal female karyotype (46, XX). No additional structural anomaly noticed. Developmental quotient assessment suggested intellectual disability.
Conclusions: A stepwise approach incidentally revealed a rare condition like atypical form of MRKH syndrome where bilateral gonadal agenesis and Mullerian duct dysgenesis were present but without any additional congenital malformations. Assessment of cognitive function in such cases should be sought for. Early detection of such rare case helps in building the emotional support of the family members in advance, long before the time when the patient might eventually present with primary amenorrhoea or infertility.
