An Uncommon, Extensive Involvement of Hydatid Cyst-Cervical Spine to Brachial Plexus

Hydatid cyst usually involves liver and lung. But it has been reported in uncommon locations like the spine and brain. There are few reports of cervical spine to brachial plexus. This report is about such extensively involved hydatid cyst management.

A 32-year-old male had complaints of neck pain, left-hand weakness, and atrophy. MRI of cervical spine and thorax revealed a multicystic lesion involving the cervical spine, vertebrae, brachial plexus, and lung apex. The lesion was removed in two stages.

Due to scarcity of literature, dense adhesions with dura and surroundings, risk of rupture, anaphylactic shock, and its management require proper planning. Excision of cervical, followed by plexus lesion, might help. Long-term use of albendazole prevents recurrence as suggested by other reports.

Extensive spinal hydatid cyst is exceptionally challenging. These behave like malignant lesions. To get the best results, surgical planning is as essential as medical management.
