Introduction:

Ilioinguinal nerve entrapment syndrome is an abdominal muscular pain, characterized by the clinical triad of muscular type iliac fossa pain with a characteristic radiation pattern, an altered sensory perception in the ilioinguinal nerve cutaneous innervation area, and a well-circumscribed trigger point medial and below the anterosuperior iliac spine.

Clinical case:

A 19 years old male with eight months of evolution characterized by chronic burning abdominal pain located on right iliac fossa with radiation to internal fifth of inguinal ligament, right root of penis and upper zone of scrotal bag, on 7 in analogue visual scale, permanent, and exacerbated by Valsalva maneuver. Physical: Positive Carnett sign, allodynia and hyperesthesia on ipsilateral scrotal bag and penis root.

Conclusion:

Ilioinguinal nerve entrapment syndrome can be treated by infiltration of a local anaesthetic confirming the diagnosis. Knowledge of this syndrome prevents unnecessary investigation.
