Case Report: Sparganosis of the Cauda Equina.

Spinal sparganosis of the cauda equina has been rarely reported. A 54-year-old man presented at the hospital after having experienced lower back pain for 10 months, progressive weakness and numbness of the left leg for 4 months, and urinary incontinence for 3 weeks. Magnetic resonance imaging of the lumbosacral spine revealed a heterogeneous enhancing mass at the T12-S1 level. Spinal sparganosis was diagnosed by histological examination and molecular identification of the parasite in the tissue section. The patient was treated with a high dose of praziquantel because the parasitic mass was only partially removed and symptoms worsened following surgery.

Dual Cestode Infection in a Thai Patient (Spinal Sparganosis and Racemose Neurocysticercosis): A Case Report.

BACKGROUND Spinal sparganosis and racemose (grape-like) neurocysticercosis are rare diseases. Co-infection with spinal sparganosis and racemose neurocysticercosis has never been reported in the English-language literature. CASE REPORT A 41-year-old male presented after having experienced left hip pain with radiation to the leg, progressive weakness and numbness of the left leg, and difficulty urinating for 4 years, all of which was caused by spinal sparganosis. He had also experienced progressive vision and hearing loss on the right side for 3 years, which were caused by racemose neurocysticercosis. Magnetic resonance imaging (MRI) of the lumbosacral spine and the brain revealed intrinsic spinal cord lesion and racemose neurocysticercosis, respectively. Spinal sparganosis was diagnosed by histological examination and an immunochromatographic test. It was treated with a high-dose of praziquantel (75 mg/kg/day) combined with cimetidine; without clinical improvement. Treatment consisted of racemose neurocysticercosis with albendazole for 2 months. A follow-up MRI of the brain revealed a minimal reduction in the amount of racemose neurocysticercosis. Repeat treatment with albendazole was administered. However, further MRI examination of the brain revealed the condition to be unchanged. Vision and hearing loss had also not improved. CONCLUSIONS In this case report, we describe a middle-aged man who presented with spinal cord symptoms (hip pain, progressive weakness and numbness of the leg, and difficulty urinating) and cranial nerve palsies (vision and hearing loss) caused by spinal sparganosis and racemose neurocysticercosis, respectively. Neurological symptoms did not improve with anthelmintic drugs.
