Traumatic rupture of hydatid cysts

Objective

To stress the relation between rupture of hydatid cysts and trauma.

Design

A case series.

Setting

A university-affiliated hospital for emergency medicine.

Patients

Four college students who suffered traumatic rupture of hydatid cysts. All injuries were sustained during sporting activities.

Interventions

Resection or unroofing of the cysts with careful removal of all hydatid elements, and suture-plication of the residual liver cavities.

Results

The ruptured cysts were located in the liver, spleen and splenic flexure of the colon. At exploration, additional hydatid cysts were found, usually in the liver. Treatment resulted in complete recovery in all patients.

Conclusions

Traumatic rupture of hydatid cysts related to sporting activities may be commoner than indicated by the rarity of reports. Increased awareness of this possibility in areas where hydatid disease is endemic is encouraged.
