Abstract OBJECTIVE: Ependymomas of the conus medullaris-cauda equina-filum terminale region are typically solitary lesions. In this report, we describe the clinical presentation, radiographic findings, operative details, and pathological features of a patient with a conus medullaris ependymoma and a filum terminale lipoma. CLINICAL PRESENTATION: A 40-year-old woman presented with increasing low back pain and bowel and bladder dysfunction. Magnetic resonance imaging revealed a partially cystic enhancing lesion at the conus medullaris and a T1-weighted hyperintense mass within the filum terminale. INTERVENTION: An L2-L3 laminotomy/laminoplasty was performed for gross total resection of the mass. Histopathological examination demonstrated a conus medullaris ependymoma and filum terminale lipoma. The patient experienced complete resolution of her preoperative symptoms. CONCLUSION: Spinal cord ependymomas are almost exclusively single lesions and their coexistence with other pathological entities is rare. In this report, we describe a patient with a concomitant conus medullaris ependymoma and filum terminale lipoma.

Abstract OBJECTIVE Huge intradural ossifications in the spine are quite rare. We report for the first time a patient with a huge intradural ossification caused by a mature teratoma at the conus medullaris. CLINICAL PRESENTATION A 68-year-old woman presented with low back pain and gait disturbance. Computed tomographic and magnetic resonance imaging revealed a huge ossification at the tip of the conus medullaris. INTERVENTION We performed L1 and L2 laminectomy and removed the mass completely. The pathological diagnosis was mature teratoma with remarkable ossification. CONCLUSION This unusual case of intradural ossification demonstrated regressive changes in a mature teratoma. Despite its tight adhesion to the conus medullaris and cauda equina, the ossified tumor was atraumatically removed with an ultrasonic aspirator.

We present a rare case of cavernous angioma of the cauda equina and review the eleven cases available in the literature. A 44-year-old woman presented with low back pain and sciatica associated with bowel and bladder dysfunction and motor weakness of the lower extremity. The MRI revealed an enhancing, heterogeneous and hyperintense intradural lesion compressing the cauda equina roots at the L4 level. Laminectomy at L3-L4 and total removal of the tumor were performed without additional neurological deficit. Pathology revealed a cavernous angioma. The literature, clinical presentation, technical examinations, and treatment are reviewed.

Abstract OBJECTIVE Myxopapillary ependymoma is a subclassification of ependymoma that is thought to be nearly exclusive to the conus medullaris or filum terminale. Primary intracerebral or brainstem myxopapillary ependymomas are rare. CLINICAL PRESENTATION An 8-year-old child presented with a 5-month history of nausea and vomiting and a 1-week history of headache. Magnetic resonance imaging revealed a nodular mass in the medulla with an associated cyst extending into the fourth ventricle. INTERVENTION A suboccipital craniotomy was performed, and a gross total resection of the lesion and cyst was achieved. Histological examination confirmed the diagnosis of myxopapillary ependymoma. A discussion of other reported cases of extraspinal myxopapillary ependymomas is presented. CONCLUSION This is the first report of a case of myxopapillary ependymoma, confirmed by histology, in the medulla. Although rare, myxopapillary ependymomas outside of the filum terminale do exist.

Cauda equina syndrome (CES) is defined as the constellation of symptoms that includes low-back pain, sciatica, saddle anesthesia, decreased rectal tone and perineal reflexes, bowel and bladder dysfunction, and variable amounts of lower-extremity weakness. There are several causes of this syndrome including trauma, central disc protrusion, hemorrhage, and neoplastic invasion. In this manuscript the authors reviewed CES in the setting of both primary and secondary neoplasms. They examined the various primary tumor types in this region as well as those representative of metastatic spread. Both surgical and nonsurgical management in this setting were studied.

Arteriovenous malformations (AVMs) of the spine display a variety of different locations, angioarchitectures, and clinical presentations. The authors describe an exceptional case of a filum terminale AVM that is not described in any classification and discuss the origin and management of this malformation. A 59-year-old woman was admitted in June 2012 for cauda equina syndrome. Magnetic resonance imaging and spinal angiography revealed an AVM of the filum terminale, located below the conus medullaris, fed by the anterior spinal artery. After an unsuccessful attempt to reach the nidus with a microcatheter, the AVM was resected. At 20 months after surgery, the patient was fully independent and radiological images confirmed the exclusion of the malformation. AVMs that originate from the filum terminale are exceptional. According to updated classifications, AVMs of the filum terminale should be categorized as a separate entity.

Nasosinus metastases from kidney cancer are an unusual clinical presentation although some cases are reported in the literature. Among these cases, sphenoidal metastases are even rarer. Here we report a case of lone sphenoid metastasis in patients with papillary renal cell cancer. Eight months after radical nephrectomy, the patient presented with progressively worsening diplopia. Magnetic resonance imaging showed a mass in the right sphenoid sinus. Histopathological examination of the biopsy sample confirmed diagnosis of sinonasal metastasis from papillary renal cell carcinoma. The patient was declined for surgical management and received stereotactic body radiation therapy. Reassessment MRI at 4 months showed a complete response of the treated sphenoid lesion.

✓ This is an analysis of 10 cases of dermoid tumor occurring in the spinal canal (8 lumbar and 2 thoracic). Low-back pain was the commonest presenting symptom, especially if the tumor was adherent to the conus medullaris. Other complaints included urinary dysfunction and motor and sensory disturbances of the legs. Clinical and radiological evidence of spina bifida was found in about half of the cases and suggested the diagnosis of a developmental type of tumor when patients presented with progressive spinal cord compression. At operation, the tumors were often found embedded in the conus medullaris or firmly adherent to the cauda equina, thus precluding complete removal. Evacuation of the cystic contents, however, gave lasting relief of the low-back pain and did not cause any deterioration in neurological function. In a follow-up study, ranging from 1 to 15 years, virtually no improvement in the neurological signs was observed. On the other hand, only one case has deteriorated due to recurrence of tumor growth.

✓ A case of a cavernous angioma of the cauda equina is presented. The patient was a 28-year-old man who experienced sudden low-back pain and headache without neurological symptoms. Lumbar puncture revealed subarachnoid hemorrhage. He had suffered a similar episode 3 years previously. Selective spinal angiography did not demonstrate any abnormal vascularity. Metrizamide myelography and magnetic resonance imaging were useful in demonstrating the presence of a tumor. Laminectomy at L1–3 and total removal of the tumor were performed without neurological deficit.

Abstract Introduction: Myxopapillary ependymoma (MPE) is a benign and slow growing tumor that originates exclusively from the conus medullaris and cauda equina nervous tissue. It occurs more commonly in young patients. In addition, clinical presentations are non-specific and may mimic benign conditions. Magnetic resonance imaging (MRI) is the imaging modality of choice for evaluating this tumor. We hereby report on two young patients with long-lasting non-specific symptoms, which were clinically attributed to benign conditions. However, cauda equina tumor was revealed on MRI in both patients. Case report: Two cases of cauda equina MPE, a 19-year-old female and a 38-year-old male, with different clinical manifestations are reported. The first patient presented with paresis and paresthesia of the lower limbs, and the second patient’s complaint was chronic low-back pain and urinary incontinence. In both cases, MRI detected a tumor originated from the cauda equina, and histopathologic examination was compatible with MPE. Conclusion: Cauda equina tumors should be considered as a differential diagnosis in the young patients presented with neurologic deficits in the lower limbs, sphincter or erectile dysfunction, and even a simple low-back pain (particularly when symptoms are long-lasting and/or progressive).
