Acute bleeding into a filum terminale ependymoma

Cervicomedullary Ependymoma with Hemorrhage: A Case Report and Review of Literature

Ependymoma is a rare tumor central nervous system that arises from the ependymal lining of the ventricles or the central canal of the spinal cord. They are of neuroectodermal in origin and constitute about 30%–86% of tumors arising in the spinal cord. The occurrence of these tumors in the cervicomedullary region is very rare. Sudden symptomatic neurologic presentations due to hemorrhage in cervicomedullary ependymoma is very rare and so far have never been reported. Mostly presenting as neurologic deficits involving limbs, these tumors pose a technical challenge in their removal. We present a patient who presented with sudden-onset dysesthesia of the upper and lower limbs. On imaging, he was found to have a cystic medullary tumor extending to the cervical region with hemorrhage. We discuss the epidemiology, surgical challenges, and outcome along with review of literature of these rare tumors located in this precarious location.

Hemorrhagic Spinal Schwannoma in Thoracolumbar Area with Total Paraplegia

Hemorrhagic schwannoma in the medulla spinalis is a rare occurrence. It is a variant of the slow-growing nerve sheath tumor that usually has subtle clinical symptoms. Injury to the spinal schwannoma that was previously suspected by spinal manipulations may accelerate the progression of symptoms and cause an acute presentation of paraplegia. We report a case of a patient that was suspected of an intradural tumor with paraparesis that initially refused treatment. Spinal manipulation procedures were performed outside of the hospital setting with subsequent advancement of paraparesis. A surgical intervention was performed, which found that the tumor mass has grown along with hemorrhage within the schwannoma. The bleeding within the mass may have caused the acute paraplegia that is rarely reported. The patient had a fair improvement on her lower motor extremity function from 1-2 to 3-4 out of 5 at six-month follow-up.

Acute Paraplegia as a Result of Hemorrhagic Spinal Ependymoma Masked by Spinal Anesthesia: Case Report and Review of Literature

Ependymomas are the most common intramedullary spinal cord tumors in adults. Although a hemorrhage within spinal ependymoma on imaging studies is not uncommon, it has rarely been reported to bea cause of acute neurological deficit. In the present report, we describe a case of a 24-year-old female patient who developed acute paraplegia as a result of hemorrhagic spinal ependymoma immediately after a cesarean delivery under spinal regional anesthesia. We review the literature of hemorrhagic spinal ependymomas presenting with acute neurological deficit and discuss the most appropriate treatment for a good neurological recovery.

Spontaneous Hemorrhage of a Spinal Ependymoma in the Filum Terminale Presenting with Acute Cauda Equina Syndrome: Case Report

We present a rare case of spontaneous hemorrhage of a spinal ependymoma in the filum terminale presenting with acute cauda equina syndrome. A 16-year-old male presented with a sudden onset of severe back pain that began 10 days before hospitalization. This symptom progressed, followed by development of decreased sensation in the lower extremities, bladder dysfunction, and motor weakness that advanced to an inability to walk. Spinal magnetic resonance imaging revealed a hemorrhagic mass from Th12 to L2 and L4 to L5, and clinical signs indicated acute cauda equina compression. One day after admission to the hospital, emergency surgery was performed. A spinal tumor in the conus portion with a spinal subarachnoid hemorrhage was seen. Gross total excision of the massive hematoma mixed with the underlying tumor was performed. Pathological findings of the excised tumor demonstrated a WHO Grade II cellular ependymoma of the non-myxopapillary type. The patient made a significant recovery. The ability to walk was restored, and impaired bladder function improved at follow-up. Early diagnosis and suitable treatment are associated with a more favorable outcome.

Spinal Intradural Schwannoma with Acute Intratumoural Haemorrhage: Case Report and Review

Schwannomas account for around half of all intradural spinal tumours, with chronic progressive symptoms as the most common presenting features. Intratumoural haemorrhage as a presenting feature of spinal schwannoma is very rare and only 11 cases have been reported till date. Authors here report a previously asymptomatic 40-year-old male who presented with acute onset paraplegia 12 hours after a minor trauma. MR imaging revealed a C7-D3 intradural-extramedullary lesion with features of acute blood and showing no enhancement. Emergency laminectomy and complete removal of the mass was performed and histopathology revealed features of schwannoma with haemorrhage. Patient had modest improvement of his neurological deficits at a follow-up of 6 months. Pertinent literature is reviewed in brief.

Acute neurological deterioration as a result of two synchronous hemorrhagic spinal ependymomas

Background:

Ependymomas are the most common intramedullary tumors in adults and are the most common in mid-adult years. The presence of synchronous ependymomas in different sites of the spine is not common and it is even more infrequent to find hemorrhage from a spinal ependymoma as a cause of neurological deterioration.

Case Description:

A 32-year-old man presented with back pain and progressive paraparesia. Magnetic resonance (MR) showed two intradural extramedullary lesions on spinal canal with signs of acute hemorrhage. The patient underwent emergent surgical decompression and resection. Pathology revealed myxopapillary ependymomas.

Conclusion:

To our knowledge, we report the first case of a patient with acute neurological deterioration as a consequence of synchronous bleeding of two spinal ependymomas located at different levels in the spinal cord. This study illustrates the importance of recognizing the rare, but known occurrence of acute neurological deterioration after spontaneous hemorrhage in spinal ependymomas.

Acute paraparesis from hemorrhagic spinal ependymoma: diagnostic dilemma and surgical management

✓Spinal ependymomas are a common type of primary spinal cord neoplasm that frequently occurs in the lumbar spine. The authors report on two patients who presented with acute neurological decline after hemorrhage into ependymomas of the filum terminale. Both were transferred to the authors' institution because of diagnostic uncertainty and a concern about possible intradural vascular abnormalities. Both patients underwent lumbar laminectomies for tumor resection. The pathological finding in each case was myxopapillary ependymoma. Both patients made a significant recovery and were ambulatory and continent at follow-up review. These cases illustrate the rare but clinically significant incidence of acute neurological decline caused by hemorrhagic cauda equina ependymomas, including the potential for delayed diagnosis and treatment.

Spontaneous hemorrhage of a spinal ependymoma: a rare cause of acute cauda equina syndrome: a case report

STUDY DESIGN

An interesting case of spontaneous bleeding from an ependymoma of the filum terminale is presented.

OBJECTIVES

To document a rare case of rapid neurologic deterioration as a consequence of spinal tumoral hemorrhage and to highlight important issues regarding tumor histologic subtype and the impact of anticoagulation that have emerged from an illuminating review of the literature.

SUMMARY OF BACKGROUND DATA

To our knowledge, there have been only 8 reported cases of hemorrhage from an ependymoma of the filum terminale or conus medullaris causing acute cauda equina syndrome. Bleeding is described in the pathology texts as being a consequence of the vascular architecture of the myxopapillary subtype and so postulated to be more common in this group. Anticoagulation is recognized to increase the frequency of tumoral bleeding, but no studies report its effect of severity of clinical presentation.

METHODS

We report the case of a 57-year-old woman who developed nontraumatic acute cauda equina syndrome, including sphincter compromise. She underwent a lumbosacral laminectomy for evacuation of a hematoma, at which stage a filum terminale ependymoma was excised. Histopathologic analysis demonstrated it to be of a nonmyxopapillary subtype.

RESULTS

The patient demonstrated gradual improvement of the neurologic deficit. At 12-month follow-up, her saddle area sensory deficit has resolved, her right lower limb is much stronger allowing her to walk long distances, and she is successfully performing intermittent self-catheterization of her bladder.

CONCLUSIONS

The possibility of an underlying tumor should always be borne in mind so that adequate preoperative planning can be undertaken. The presence of the myxopapillary subtype should not prevent a clinician from excluding other reasons for hemorrhage, and counseling when reinstituting anticoagulation must include warning against a worse prognosis from any future hemorrhage.

Traumatic intratumoral hemorrhage as the presenting symptom of a spinal neurinoma. Case report

Intratumoral hemorrhage as the presenting symptom of spinal tumors is rare. The authors describe a patient who presented with rapidly progressing paraplegia 24 hours after sustaining a minor traumatic injury of the thoracic spine. Radiological evaluation demonstrated a low-thoracic intradural tumor that was resected and found to be a neurinoma in which severe intra- and peritumoral hemorrhage was revealed. The radiological, surgical, and pathological findings are presented and discussed.

Subdural hemorrhage of the cauda equina. A rare complication of cerebrospinal fluid shunt. Case report

We describe the case of a 16-year-old boy with idiopathic hydrocephalus, who developed cranial subdural hygromas and subsequent cranial subdural hemorrhage after a shunting procedure. Sciatica and radicular lumbar pain initially seemed to be unrelated to the proceeding implantation of a ventriculoatrial shunt. CT scan revealed a sharply demarcated hyperdensity in the lumbar subdural space with compression of the cauda equina. Differential diagnosis considerations included vascular malformations, vascular tumors, benign tumors of meninges or nerve sheets, ependymoma, lymphoma, and metastases. MR investigation did, in fact, clearly recognize this hyperintense space-occupying lesion as blood in the subdural space which outlined the cauda equina. We believe that the spinal subdural hematoma in our case represented an extension of intracranial subdural haemorrhage fluid into the spinal subdural space.

Spinal tumors and subarachnoid hemorrhage: pathogenetic and diagnostic aspects in 5 cases

The authors report 5 cases of spinal tumor associated with subarachnoid hemorrhage. Histologically, the tumor was an ependymoma in 2 cases, a neurinoma in 2 cases and a hemangioblastoma in 1 case. The pathogenetic and diagnostic characteristics of these 5 cases are analyzed in the light of other published reports.

A cauda equina syndrome in a patient treated with oral anticoagulants. Case report

The authors report a patient who was on oral anticoagulants because of mitral valve disease and who developed paraplegia from subarachnoid bleeding involving the cauda equina. The differential diagnosis, investigations and treatment of the cauda equina syndrome are described.

Spinal subarachnoid hemorrhage due to a filum terminale ependymoma

We present a case of spinal subarachnoid hemorrhage due to an ependymoma of the filum terminale in a 23-year-old male. Clinical signs indicating a spinal origin of the subarachnoid hemorrhage are discussed. Subarachnoid hemorrhages are only rarely caused by an intraspinal tumor, most of which are located in the cauda equina. Our findings in this case proved the value of MRI examination in tumors of the cauda equina.
