We present the unusual case of a woman presenting with an incarcerated umbilical hernia. Intraoperatively, the contents of the hernia were found to be an ovary. We outline the clinical presentation of our patient, investigations and management as well as a discussion on unusual contents of umbilical hernias. To our knowledge, this is the first case of a non-malignant ovary incarcerated in an umbilical hernia.
KEYWORDSHernia -Umbilicus -Surgical mesh -Ovary Accepted 6 September 2013; published online XXX CORRESPONDENCE TO Usama Ahmed, E: usama.x@hotmail.fr Umbilical hernias are common, occurring in 10% of all infants.1 In adults, however, they often represent an acquired defect, possibly related to intra-abdominal pathology. We present our own experience of unusual contents of an umbilical hernia, its management and a brief literature review.
Case HistoryA 45-year-old nulliparous woman of Zimbabwean origin presented to our emergency department complaining of a 5-day history of an increasingly tender, swollen, irreducible mass at the umbilicus. On further enquiry, it transpired that this previously reducible mass had been present for approximately one year's duration, tender during her periods but otherwise asymptomatic. She reported regular, heavy periods with clots and flooding, and denied possible pregnancy. Her only past medical history was of a myomectomy for a uterine fibroid 11 years earlier. She denied a previous history of a childhood umbilical hernia. On systems review, she had no weight loss or loss of appetite. She had been opening her bowels normally, had not vomited, and was eating and drinking normally. On examination, the patient was haemodynamically stable and clinically well. Her abdomen was distended and a tense umbilical mass visible with overlying inflammatory hyperpigmented skin changes. Palpation of the abdomen revealed a tender, irreducible umbilical mass with a negative cough impulse. Abdominal ascites were absent. An irregularly contoured, 20-week sized fibroid uterus reaching the umbilicus and more palpable in the right abdomen was discovered.Blood tests revealed raised inflammatory markers and severe anaemia. The patient was transfused with two units of blood preoperatively and iron supplements were commenced. Erect abdominal radiography revealed no acute obstruction or perforation.Our main differential diagnosis was that of an incarcerated umbilical hernia with a differential of an abscess. The patient was consented for repair of umbilical hernia and operated on later that evening. A curvilinear subumbilical incision was used to approach the hernia. A true umbilical hernia coming through the umbilical stalk was visualised. The hernial sac was opened at the neck to reveal an ovary (Fig 1). The ovary was seen to be viable and so reduced through the defect. The defect was closed with an onlay polypropylene mesh and a suction drain left in situ. Postoperative ultrasonography showed multiple uterine fibroids with the largest measuring 8.6cm in diameter (Fig 2). The patient was disch...
