Hydatid cyst of the psoas: case report and review of literature.

UNLABELLED

Hydatid disease (HD) is a parasitic pathology that remains endemic in Morocco and poses a public health problem. Its location in the psoas muscle is a rare entity. We report this case highlighting the diagnostic challenges, therapeutic modalities as well as prognosis.

CASE PRESENTATION

We report the case of a 40-year-old male patient without a notable pathological history, referred to our department for management of a paravertebral hydatid cyst mass with fluid density and scalloping on the verteral body on thoraco-abdomino-pelvic computed tomography scan. After a pretherapeutic assessment, the patient underwent an exploratory laparotomy which objective a deep right laterovertebral mass. The patient underwent a resection of the protruding dome, lavage using hydrogen peroxide and drainage of the residual cavity. The patient recovered well and was discharged 5 days later on albendazole 10 mg/kg/d. The anatomopathological analysis of the specimen confirmed the diagnosis of hydatid cyst. The evolution was satisfactory for the patient with a recall of 6 months.

DISCUSSION

Hydatidosis is an anthropozonosis caused by the larval form of . It can reach the psoas muscle by great circulation. The diagnosis of HD in the psoas is often difficult. Biology and imaging confirm the diagnosis and the standard treatment remains surgery.

CONCLUSION

HD of the psoas is a rare entity. The diagnosis is based on biology and imaging, and radical treatment is surgery.
