Spigelian hernia.

Abstract

Introduction: Spigelian hernia is a rare type of abdominal wall hernias which are often diagnosed when incarcerated. These hernias typically develop at the crossing point of the arcuate line and lateral portion of rectus abdominis muscle.

Case report: We present the case of a 44-year-old female patient admitted to our surgery unit for a painful lump in her right mesogastrium. Incarcerated atypical hernia in the right mesogastrium was suspected based on completed imaging assessments. Spigelian hernia was confirmed by preoperative findings. Interestingly, the patient applied interferon (multiple sclerosis therapy) at the site of the lump, which is why the diagnosis of lipodystrophy had been considered.

Conclusion: In general, the diagnosis of Spigelian hernia is difficult. From the anatomical point of view the clinical finding is not always specific. The risk of incarceration is relatively high, and thus even clinically silent findings are indicated for surgery.
