Massive Cystic Degeneration Of Neglected Leiomyoma Mimicking An Ovarian Tumour In A 48 Year Old Woman

Abstract

Introduction: Leiomyomas are common benign tumours of the female pelvis with growth and extension not limited to pelvis. The occurrence of solitary or multiple nodules are initially asymptomatic except when it is occurring within the cavity of the uterus. Symptoms would however develop with time if not properly treated or ignored, which could lead to live-threatening complications. Case Presentation: This is a report of a 48-year-old woman with neglected leiomyoma who presented with an enormous abdominal distension due to massive cystic degeneration of the leiomyoma mimicking an ovarian tumor. An abdominal ultrasound scan performed revealed a large solid-cystic abdominal mass on which account an exploratory laparotomy where total abdominal hysterectomy left salpingectomy and bilateral oophorectomy was performed. The histopathology report of the tumour revealed it was a benign fibromyoma (leiomyoma) with degenerative changes. The ovaries and left tube were all normal. Conclusion: Leiomyoma though a benign tumour, can grow disproportionately and undergo degenerative changes if neglected. This can result in life-threatening sequelae, mimicking a malignant tumour.
