Subependymoma


Presentation

  • By presenting our case report, we hope to draw attention to this rare but potentially life-threatening presentation of subependymoma.[ncbi.nlm.nih.gov]
  • Clinical presentation, radiological, and pathological studies of this case of subependymoma are presented. The incidence of spinal subependymoma was also discussed in light of a literature review.[ncbi.nlm.nih.gov]
  • They often present clinically with pain and neurologic symptoms, including motor, sensory, urinary, and sexual dysfunction.[ncbi.nlm.nih.gov]
  • The tumor presented here is unique in that several atypical pathological features were found in an otherwise typical subependymoma.[ncbi.nlm.nih.gov]
  • This 39-year-old man presented with a 6-month history of occipital headaches. Magnetic resonance imaging revealed an irregularly shaped fourth ventricle mass.[ncbi.nlm.nih.gov]
Spontaneous Hemorrhage
  • A spontaneous hemorrhagic event within an asymptomatic lateral ventricle subependymoma can result in a surgical emergence as a consequence of sudden obstruction of cerebrospinal fluid pathways.[ncbi.nlm.nih.gov]
Asymptomatic

  • The patient's tumor was asymptomatic for many years. Imaging findings included asymmetry of the lateral ventricles.[ncbi.nlm.nih.gov]
  • They usually occur in elderly men and often are asymptomatic and discovered incidentally. We report a case of a 6-year-old girl with a symptomatic subependymoma in the third ventricle with MR imaging.[ncbi.nlm.nih.gov]
  • To the authors' knowledge, this is the first reported case of rapid, nonhemorrhagic expansion associated with necrosis in a previously asymptomatic subependymoma.[ncbi.nlm.nih.gov]
  • Subependymomas are benign intraventricular tumors with an indolent growth pattern, which are usually asymptomatic, and most commonly occur in the fourth and lateral ventricles.[ncbi.nlm.nih.gov]

Myelopathy
  • The patient experiencing myelopathy symptoms underwent a surgical resection of cervical spinal cord subependymoma that resulted in return to normal function.[ncbi.nlm.nih.gov]
  • Most of the intraventricular subependymomas are subclinical and thus incidentally encountered at autopsy, whereas the spinal ones are inevitably accompanied by myelopathy and are often diagnosed clinically as ependymomas or astrocytomas.[ncbi.nlm.nih.gov]
  • CONCLUSIONS: Subependymomas are indolent tumors that when symptomatic can present with cerebrospinal fluid (CSF) obstructive symptoms in the brain and myelopathy in the spinal cord. There is no one symptom diagnostic for subependymomas.[ncbi.nlm.nih.gov]
  • Conclusions: Subependymomas are indolent tumors that when symptomatic can present with cerebrospinal fluid (CSF) obstructive symptoms in the brain and myelopathy in the spinal cord. There is no one symptom diagnostic for subependymomas.[jhu.pure.elsevier.com]
Meningism
  • The autopsy showed brain and pulmonary edema, numerous small meningeal meningiomas, bilateral and symmetrical juxtaventricular meningiomas, and a well-demarcated gray tan tumor in the medulla oblongata and upper cervical spinal cord.[ncbi.nlm.nih.gov]

Altered Mental Status
  • The patient developed sudden onset of headache and altered mental status followed by complete resolution, likely due to intermittent hydrocephalus.[ncbi.nlm.nih.gov]

Workup

  • Conclusions: The case is an educative example about the necessity to keep possible intracranial lesions in mind when starting the workup of a patient presenting with erectile dysfunction.[endocrine-abstracts.org]
  • 4th ventricle, symptoms are related to obstruction and subsequently increased intracranial pressure In spinal ependymomas, presentation is typically with sensory deficits (compared with astrocytomas, which tend to present with pain and motor symptoms) Workup[en.wikibooks.org]
HLA-DR2
  • She was positive for HLA-DR2. At autopsy there was a tumour dorsal to the fourth ventricle which involved the midbrain tectum and rostral pons. Histologic examination of the tumour confirmed it to be a subependymoma.[ncbi.nlm.nih.gov]

Treatment

  • Consequently, we explore the SEER database to evaluate prognostic and treatment factors associated with intracranial subependymoma.[ncbi.nlm.nih.gov]
  • After a careful review of the literature, the optimal treatment of this spinal tumour is debated.[ncbi.nlm.nih.gov]
  • The child may have had treatment to relieve signs or symptoms caused by the tumor. Subependymoma Treatment of newly diagnosed subependymoma (WHO ... 4 ...[familydiagnosis.com]
  • Surgical extirpation is one of the treatment options to establish the correct diagnosis and to prevent symptoms.[ncbi.nlm.nih.gov]
  • We document a successful case of radiosurgical treatment of a multiply recurrent subependymoma.[ncbi.nlm.nih.gov]

Prognosis

  • The pathology, the clinical findings and the prognosis of this tumour are discussed.[ncbi.nlm.nih.gov]
  • Although radical removal is considered the rational goal of treatment, larger experience is necessary to know both the rate of growth and prognosis of subependymomas when these tumors arise within the spinal cord.[ncbi.nlm.nih.gov]
  • They are biologically benign with low proliferative index, hence postoperative prognosis is very good. We present a case of a 42-year-old male patient with an intramedullary Subependymoma located within the central canal of thoracic region cord.[ncbi.nlm.nih.gov]
  • Recognition of subependymoma should prompt the surgeon to attempt radical tumor removal because it can be achieved without sacrificing contiguous tissue and carries a good prognosis.[ncbi.nlm.nih.gov]
  • Tumors, attached to the floor of the fourth ventricle carry the worst prognosis, because of the location. A mixed ependymomasubependymoma carries a worse prognosis than a pure subependymoma.[ependymomas.com]

Etiology

  • This case lends support to the notion that some subependymomas are reactive in etiology.[ncbi.nlm.nih.gov]
  • Subependymomas have been described with features identical to this case, however, since these commonly present as non-enhancing intraventricular lesions [5,7], it was felt to be a less likely etiology.[sciforschenonline.org]
