Intramedullary neurenteric cyst of the conus medullaris without associated spinal malformation: a case report and review of the literature

Spinal neurenteric (NE) cysts are rare congenital anomalies that may occur either alone or in the context of a complex malformative disorder. They are usually intradural-extramedullary lesions. Intramedullary NE cysts not associated with other congenital anomalies are very rare and only a few cases have been reported in the conus medullaris region. Intramedullary neurenteric cysts not associated with other spinal anomalies are very rare especially in the conus medullaris region. MRI is useful to define the cyst and the osseous anomalies associated with this lesion. The goal of treatment of an intramedullary neurenteric cyst is total excision at the first operation, if possible. Life-long follow-up with annual MRI is recommended due to the risk of cyst recurrence. We report an intramedullary NE cyst of the conus medullaris without associated malformation and the relevant literature is briefly reviewed.     

Intramedullary conus medullaris metastasis of periurethral adenocarcinoma

Intramedullary spinal cord metastasis to the conus medullaris is very rare. We report a 44-year-old woman with an intra-axial conus medullaris metastasis from periurethral adenocarcinoma. To our knowledge, this is the first report in the literature. We also discuss the clinical features, possible pathophysiological mechanisms and treatment options for intramedullary spinal cord metastasis to the conus medullaris.

Sparganosis presenting as a conus medullaris lesion: case report and literature review of the spinal sparganosis

BACKGROUND: Sparganosis is a rare parasitic infection affecting various organs, including the central nervous system. In rare cases, sparganosis may involve the spinal cord, usually at the thoracic area. We herein report, to our knowledge, the first case of sparganosis presenting as a conus medullaris lesion and review the literature of sparganosis involving the spinal cord. OBSERVATION: A 42-year-old man presented with progressive perianal paresthesia and sphincter disturbances. Results of enzyme-linked immunosorbent assay of the cerebrospinal fluid and surgical biopsy were consistent with sparganum infection affecting the conus medullaris. We reviewed 7 other cases of spinal sparganosis. CONCLUSIONS: Sparganosis may present as a conus medullaris lesion. This possibility should be considered when clinicians encounter patients with a conus medullaris lesion or cauda equina syndrome with uncertain diagnosis.     

Intramedullary spinal cysticercosis

Intramedullary cysticercosis of the spinal cord is rare; there have been only 26 previous cases. We describe a patient with low back pain, paraparesis, lumbosacral sensory loss, and signs of meningeal irritation. The clinical diagnosis was spinal cord tumor, but at surgery there was a cysticercus cyst within the lumbosacral cord. Careful search did not reveal the parasite in any other part of the body. This is the first case of spinal cysticercosis reported in Japan.     

Early vesico-ureteral reflux following conus medullaris injury: case report

The authors describe severe vesico-ureteral reflux and simultaneous renal insufficiency which occurred after a spinal cord injury to the conus medullaris. They point out the misleading character of these injuries when there are only minimal neurological signs in the trunk and limbs. The main clinical consequence may be an isolated neuropathic bladder which, if not detected, delays treatment. Additionally, they underline the role of mixed bladder and sphincter lesions in the development of renal insufficiency; also the role of increased intravesical pressure during filling and emptying with bilateral vesico-ureteral reflux.     

Coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation in an adult: a case report

The coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation (AVM) is exceptional, which has not been reported previously in the literature. The precise mechanism of the coexistence of these conditions is not known, however, the dysembryonic origin of spinal cord teratoma and AVM seems to play a part in this process. A 34-year-old male patient was admitted with lower back pain, bilateral lower extremity numbness and weakness, and sexual disturbance. Magnetic resonance imaging (MRI) showed an AVM extended cranially from the top of a heterogeneous expansile lesion of the conus medullaris. Surgical exploration and histopathological examination revealed a mature teratoma associated with the AVM. A literature review supported the dysembryonic origin of spinal cord teratomas and AVMs. This unique case may provide insight into the etiopathogenesis of the coexistence of spinal teratoma of the conus medullaris and AVM.     

Intramedullary spinal cord abscess: a case report

An 11-year-old boy presented with pain in the back, urinary retention, paraplegia and loss of sensations below L1. Investigations revealed an intramedullary lesion. An intramedullary spinal cord abscess was found at surgery. The pus was evacuated and abscess was excised. Minimal recovery was seen following surgery. Early intervention and a high index of suspicion is required in such cases.
