Rare Form of Femoral Hernia: Femorocele in a 63-Year-Old Woman

Strategic Insights

— 1 min read

Researchers at Kanto Central Hospital of the Mutual Aid Association of Public School Teachers in Tokyo, Japan have reported a rare case of femorocele, a form of femoral hernia. According to the study, the condition was initially misdiagnosed as a ganglion, highlighting the need for careful interpretation of imaging findings to avoid misdiagnosis. The patient underwent elective surgery, where the hernia sac was reduced into the abdominal cavity, and the hernia was repaired using a mesh placed in the preperitoneal space.

Key Takeaways:

  • Femorocele is a rare form of femoral hernia characterized by a hydrocele originating from the peritoneum and protruding into the femoral canal.
  • The condition is often misdiagnosed, with most cases identified intraoperatively or postoperatively, or initially misdiagnosed as other conditions.
  • The patient, a 63-year-old woman, presented with a right-sided groin swelling, which was initially suspected as a ganglion.
  • Physical examination revealed a non-reducible and painless mass lateral to the pubic tubercle.
  • CT scan revealed a hydrocele, measuring 57.4 mm in max, medial to the common femoral vessels and caudal to the inguinal ligament.
  • Elective surgery via the anterior approach revealed a hydrocele originating from the peritoneum and protruding into the femoral canal, consistent with a diagnosis of femorocele.
  • The hernia sac was reduced into the abdominal cavity, and the hernia was repaired using a mesh placed in the preperitoneal space.
  • The patient had an uneventful recovery and was discharged on postoperative day 3.
  • Femorocele requires careful interpretation of imaging findings to avoid misdiagnosis and treatment with surgery is the only mean for establishing a definitive diagnosis and providing curative treatment.

Statistics:

  • 63-year-old woman presented with a right-sided groin swelling.
  • The hydrocele measured 57.4 mm in max, medial to the common femoral vessels and caudal to the inguinal ligament.
  • The hernia sac was reduced into the abdominal cavity.
  • The hernia was repaired using a mesh placed in the preperitoneal space.
  • The patient had an uneventful recovery and was discharged on postoperative day 3.
