Case Report: Sparganosis of the Cauda Equina.

ABSTRACT: 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.

Sparganosis presenting as cauda equina syndrome with molecular identification of the parasite in tissue sections.

Project description:A 52-year-old woman presented with lower back pain, progressive symmetrical paraparesis with sensory impairment, and sphincter disturbance. Magnetic resonance imaging (MRI) of the whole spine revealed multiple intradural extramedullary serpiginous-mass lesions in the subarachnoid space continuously from the prepontine to the anterior part of the medulla oblongata levels, C7, T2-T8, and T12 vertebral levels distally until the end of the theca sac and filling-in the right S1 neural foramen. Sparganosis was diagnosed by demonstration of the sparganum in histopathological sections of surgically resected tissues and also by the presence of serum IgG antibodies by ELISA. DNA was extracted from unstained tissue sections, and a partial fragment of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene was amplified using a primer set specific for Spirometra spp. cox1. After sequencing of the PCR-amplicon and alignment of the nucleotide sequence data, the causative agent was identified as the larva of Spirometra erinaceieuropaei.

Primary spinal Non-Hodgkin Lymphoma presenting as impending cauda equina syndrome: A case report.

Project description:IntroductionMalignant lymphoma (ML) can involve the central nervous system either primarily or by secondary spread, which tends to occur late in the disease as part of widespread dissemination. Lymphoma presenting as primary tumors of the spinal cord is extremely uncommon. Primary spinal lymphoma if detected early can have a good prognosis with no relapse after effective treatment.Case presentationA 32 years old male patient presented with the symptoms of impending cauda equina syndrome which was managed with surgery and chemotherapy. The patient was successfully treated without the relapse of his condition at his 6 months follow-up scan.Discussion: Primary spinal non-Hodgkin lymphoma is a rare entity among extranodal non-Hodgkin lymphoma. MRI is usually non-confirmatory and needs immunohistochemistry for the correct diagnosis. R-CHOP regimen is the standard chemotherapy regimen. Surgical decompression is required in cases of impending neurological injury along with radiotherapy.ConclusionPrimary spinal epidural diffuse large B-cell lymphoma should be considered as a differential diagnosis in patients presenting with back pain and symptoms of impending cauda equina syndrome. It is important to early detect and treat the disease to prevent permanent neurological injury and metastasis.

Foix-alajouanine syndrome presenting as acute cauda equina syndrome: a case report.

Project description:Study Design Case report. Objective Present a case of Foix-Alajouanine syndrome that presented as acute cauda equina syndrome and discuss the pathophysiology and management. Methods An adult male patient developed sudden onset of back pain and leg pain with weakness of the lower limbs and bladder/bowel dysfunction typical of cauda equina syndrome. Emergency magnetic resonance imaging revealed no compressive lesion in the spine but showed tortuous flow voids and end-on blood vessels in the peridural region suggesting spinal arteriovenous malformation resulting in Foix-Alajouanine syndrome. Results The case was managed by endovascular embolization with excellent results. The pathophysiology, imaging features, management, and literature review of the syndrome is discussed. Conclusion The authors conclude that this condition may be an important differential diagnosis for cauda equina syndrome.

Surgical treatment of progressive cauda equina compression caused by spontaneous spinal subdural hematoma: A case report.

Project description:RationaleSpontaneous spinal subdural hematoma (SSDH) without an underlying pathology is a very rare condition. The treatment protocol for SSDH is early diagnosis and treatment before irreversible damage to neural tissue. However, there is no agreement on the etiopathogenesis, as well as the need for surgery to treat spontaneous SSDH. Here, we report a rare case of spontaneous SSDH with progressive deterioration and symptoms of cauda equina syndrome after ineffective conservative treatment.Patient's concernA 38-year-old male patient presented with sudden lower back and bilateral leg pain.DiagnosisA magnetic resonance imaging (MRI) scan on the third day after the onset of symptoms revealed a subdural hematoma from L1 to S1, presenting as hyperintensities on T1 weighted sequences and hypointensities to isointensities on T2 weighted sequences.InterventionLaminectomy and subdural evacuation were performed immediately.OutcomesAn abnormal ligamentum flavum was observed intraoperatively. A histological examination revealed extravasation of blood in the degenerated ligamentum flavum. Postoperatively, the lower limb pain improved immediately. At the 6-month follow-up, the pain and numbness of the lower limb disappeared, and the muscle strength of both legs recovered completely with normal gait.LessonsSpontaneous SSDH with ligamentum flavum hematoma was caused by a sudden increase of intravenous pressure, resulting from a marked surge in the intra-abdominal or intrathoracic pressure. Consecutive MRI scans provided valuable information, leading to a diagnosis of spontaneous SSDH. The treatment protocol for spontaneous SSDH should be determined based on the location and stage of the hematoma, as well as the subject's neurological status.

Isolated neurocysticercosis of the spine presenting with low back pain and cauda equina syndrome: a case report.

Project description:IntroductionCysticercosis, caused by Cysticercus cellulosae, is one of the common parasitic diseases that can affect the central nervous system (neurocysticercosis, NCC). Isolated involvement of cysticercosis of the spine, without the involvement of the brain, has been very rarely reported.Case presentationThis report presented a case, who was presenting with low back pain with radiation and cauda equina syndrome (CES). On MRI, the patient was found to have a subarachnoid cystic lesion at the level of lumbosacral vertebrae. Under neurosurgery, the patient underwent L5/S1 laminectomy, decompression, and excision of the cyst. On histopathological examination, the patient was diagnosed of having Cysticercosis. Immediately after surgery, the patient had neurological deterioration. However, at the end of 1 year, the patient had significant improvement both neurologically and functionally.DiscussionSpinal NCC should be considered in the differential diagnosis for a patient, who presents with a cystic lesion in the spinal subarachnoid space. Surgical exploration and excision of the cysts should be conducted not only to establish the diagnosis but also to decompress the cord and peripheral nerves.

Bullet retrieval from the cauda equina after penetrating spinal injury: A case report and review of the literature.

Project description:BackgroundWhen gunshot injuries occur to the spine, bullet fragments may be retained within the spinal canal. Indications for bullet removal include incomplete spinal cord injury, progressive loss of neurologic function including injury to the cauda equina, and dural leaks with impending risk of meningitis.Case descriptionHere, we present a 34-year-old male with a missile penetrating spinal injury to the cauda equina. In addition to the computed tomography scan demonstrating retention of a bullet in the left L1/2 disc space, the scan suggested likely dural injury. The patient underwent a decompression/instrumented fusion with retrieval of the retained bullet fragment. A laminectomy was performed from T12 to L3, and at L1 and L2, a large traumatic durotomy was identified and repaired. The patient, unfortunately, continued to have bilateral lower extremity plegia with neurogenic bladder/bowel dysfunction at 1-year follow-up.ConclusionWe discuss the operative management and provide an intraoperative video showing the bullet extraction and dural closure.

Microsurgical resection of giant T11/T12 conus cauda equina schwannoma.

Project description:In this video, we highlight the anatomy involved with microsurgical resection of a giant T11/T12 conus cauda equina schwannoma. Spinal schwannoma remains the third most common intradural spinal tumor. Tumors undergoing gross total resection usually do not recur. To our knowledge, this is the first video case report of giant cauda equina schwannoma resection. A 55-year-old female presented with paraparesis and urinary retention. Lumbar spine MRI revealed a contrast-enhancing intradural extramedullary tumor at the T11/T12 level. Surgery was performed in the prone position with intraoperative neurophysiology monitoring (somatosensory and motor evoked potentials-SSEPs and MEPs). T11/T12 laminectomies were performed. After opening the dura and arachnoid, the tumor was found covered with cauda equina nerve roots. We delineated the inferior pole of the tumor, followed by opening of the capsule and debulking the tumor. Subsequently, the cranial pole was dissected from the corresponding cauda equina nerve roots. Finally, the tumor nerve origin was identified and divided after nerve stimulation confirmed the tumor arose from a sensory nerve root. The tumor was removed; histological analysis revealed a schwannoma (WHO Grade I). Postoperative MRI revealed complete resection. The patient fully recovered her neurological function. This case highlights the importance of careful microsurgical technique and gross total resection of the tumor in the view of favorable postoperative neurological recovery of the patient. Intraoperative use of ultrasound is helpful to delineate preoperatively tumor extension and confirm postoperative tumor resection.
