MISSED DIAGNOSIS OF DERMOID CYST IN EARLY PREGNANCY CAUSING OBSTRUCTED LABOUR: CASE REPORT

Abstract :

INTRODUCTION: Adnexal masses in pregnancy are common with a prevalence rate of 0.19–8.8%. Adnexa should always be assessed at routine ultrasound examination in early pregnancy so that early identification of a mass can be valuable in subsequent management of the pregnancy. The enlarging uterus gradually displaces the adnexa and obscures its view, especially as pregnancy advances, making radiological assessment of adnexal masses difficult. CASE PRESENTATION: We report a rare case of a large dermoid cyst, misdiagnosed as fioid at 14 weeks of gestation. Later on as the diagnosis was indeterminate, MRI was done at 34 weeks and a large dermoid cyst was reported. Patient had to undergo LSCS for obstructed labour and fear of rupture of cyst. CONCLUSION: Dermoid cysts less than 6 comes are generally asymptomatic in pregnancy. Cysts greater than 6 cms. are prone to torsion. When ultrasound scans reveal indeterminate masses, magnetic resonance imaging (MRI) is helpful for identifying features that suggest ‘fat content’, which is diagnostic of a mature dermoid cyst. A dermoid cyst more than 10 cms can cause obstructed labour and needs to be removed at 16–18 weeks of gestation.
