Abstract

Primary hydatid cyst of the spinal canal is extremely rare. We reported a 42-year-old Kazakh man with right lower back pain and weakness in both lower limbs for 2 months, who lived in the pastoral area. Clinical examination revealed that the patient had no cysts on other organs and no previous medical history except for a huge cyst inside and next to the vertebrae. MRI examination revealed a huge dumbbell-shaped primary cyst across the intervertebral foramen. Pathological examination after operation confirmed a fine-grained hydatid cyst disease. Therefore, in the pastoral area, doctors should be alert to the occurrence of hydatid cyst disease if patients complained about progressive back pain and lower limb weakness or other spinal cord compression symptoms. Once hydatid cysts in other organs or systems were detected, the occurrence of the disease could be highly suspected. Complete resection is an effective treatment for hydatid cyst disease.

Highlights

Hydatid cyst disease, known as echinococcosis, is a parasitic disease that affects humans and other mammals such as sheep, dogs, mice, and horses, relatively common in livestock areas
We found that after Hematoxylin and Eosin (H&E) staining of the tissue, granulomas and inflammatory granulation tissue could be seen, consisting of proliferative fibers, vascular epithelioid cells, and multinucleated giant cells
The main infectious source of this disease is livestock, most of which are caused by the invasion of Echinococcosis Granulosa into the human body, and a few are caused by Echinococcosis Multilocularis

Summary

INTRODUCTION

Known as echinococcosis, is a parasitic disease that affects humans and other mammals such as sheep, dogs, mice, and horses, relatively common in livestock areas. To the best of our knowledge, primary hydatid cyst of the spinal canal across the intervertebral foramen has been rarely and seldom reported in the literature This case report describes a rare presentation of primary extradural intraspinal and paravertebral connected primary hydatid disease. It was the Dumbbell-Shaped Primary Hydatid Cyst first time that the initial diagnosis of the patient was the hydatid cyst disease, but no hydatid involvement was found in other organs except the spinal area, the serological test (ELISA) of echinococcosis was negative. The oval solidcystic cavity with clear boundaries located at extradural (across the intervertebral foramen and the dumbbell extension was intraspinal) and had compressed the spinal cord to the left ventral side. We advise the patient to take the medication on time and to review for further imaging every 6 months
