Multiple spinal intramedullary cavernous angiomas with bleeding episode mimicking an intramedullary tumor.

J Radiol Case Rep 2022 Mar 1;16(3):15-22. Epub 2022 Mar 1.

Anatomical Pathology Department, Faculty of Medicine, Universitas Airlangga, Indonesia.

Intramedullary cavernous angioma is a rare vascular malformation compared to cerebral cavernous malformation. The incidence of cavernous angioma is about 3 - 5% of all central nervous system lesions, 5 - 12% of all spinal vascular lesions, and 1% of all intramedullary lesions in pediatric patients. Although intramedullary cavernous angioma has the same histological picture as cerebral cavernous angioma, the natural history, and surgical approach are different from cerebral cavernous angioma.

A rare tumor case in an adult patient with neurofibromatosis: Lumbar ependymoma.

Niger J Clin Pract 2022 Feb;25(2):197-199

Department of Neurosurgery, Fırat University, Elazığ, Turkey.

In patients with type 1 neurofibromatosis (NF1), there is an increased susceptibility to tumor development in the central nervous system due to the loss of neurofibromin, an inactivator of the protooncogene Ras. NF1 has a broad clinical spectrum,which includes spinal tumors. Although the most common intramedullary tumor of the spinal cord in adults is ependymoma, few patients with NF1 accompanied by spinal ependymoma have been reported to date, and the localization of the tumors is cervical and thoracic in these cases.

Multisegment Intradural Extramedullary Ependymoma.

Cureus 2021 Dec 10;13(12):e20329. Epub 2021 Dec 10.

Neurosurgery, Vasal Hospital Neuro and Trauma Centre, Jalandhar, IND.

Ependymomas are commonly reported at an intradural intramedullary location and more frequently at the conus medullaris or filum terminale. In comparison to this, the incidence of spinal tumors being reported at an intradural extramedullary site is less. We describe a young patient who presented with urinary retention and a long-standing history of back pain radiating to the right lower limb.

Myxopapillary ependymoma with interval postoperative CSF seeding: A report of an unusual case.

Radiol Case Rep 2021 Dec 10;16(12):3838-3843. Epub 2021 Oct 10.

Radiology Department, Rush University Medical Center, Chicago, Illinois, USA.

Myxopapillary ependymoma (MPE) is a unique slow-growing benign (WHO grade 1) subtype of spinal cord ependymoma arising predominantly in the filum terminale. Despite its benign nature, it occasionally disseminates through the cerebrospinal fluid and metastasizes to distant sites. Here, we report an extremely rare case of MPE with interval CSF seeding and metachronous metastasis in a 47 -year-old female presented as a gradually increasing low back pain for three months with bilateral radiculopathy down to the knees.

Tanycytic ependymoma: highlighting challenges in radio-pathological diagnosis.

Indian J Pathol Microbiol 2021 Oct-Dec;64(4):633-637

Department of Neurosurgery, GIPMER, Jawaharlal Nehru Marg, New Delhi, India.

Background: Tanycytic ependymoma (TE) (WHO grade II) is a rare and morphologically distinct variant of ependymoma with only 77 cases reported worldwide so far. Variable clinical and radio-pathological features lead to misdiagnosis as WHO grade 1 tumors. On imaging, differentials of either schwannoma, meningioma, low-grade glial (like angiocentric glioma), or myxopapillary ependymoma are considered. Read More

Spinal Ependymoma Identified Following Spinal Anesthesia for Cesarean Delivery.

Cureus 2021 Jan 7;13(1):e12558. Epub 2021 Jan 7.

Anesthesiology, McGovern Medical School, University of Texas Health Science Center, Houston, USA.

Neuraxial anesthesia is preferred over general anesthesia for cesarean delivery when appropriate because the latter is associated with a higher incidence of airway complications and an increased need for neonatal resuscitation. Common complications of neuraxial anesthesia include backache and headache, whereas feared but rare complications include paraplegia, intraspinal hemorrhage, cauda equina syndrome, nerve injury, and epidural hematoma. This case report presents a 40-year-old female with undiagnosed and asymptomatic ependymoma who presented with concerning neurological symptoms after receiving spinal anesthesia for elective cesarean delivery.

BMJ Case Rep 2020 Dec 17;13(12). Epub 2020 Dec 17.

Medical Oncology, The Queen Elizabeth Hospital, Adelaide, South Australia, Australia.

Myxopapillary ependymoma (MPE) is a rare glial tumour mainly located in the areas of the conus medullaris, cauda equina and filum terminale of the spinal cord. Ectopic MPE tends to behave more aggressively and distant metastases are often seen. Unfortunately, no standard treatment options are established as only small series of treated patients and a few reported cases are available in the literature. Read More

MRI characteristics and resectability in spinal cord glioma.

Clin Neurol Neurosurg 2021 01 19;200:106321. Epub 2020 Oct 19.

Department of Neurosurgery, University of Iowa Carver College of Medicine, Iowa City, IA USA. Electronic address:

Objective: The histopathology of intramedullary spinal cord tumors (IMSCT) can be suspected from the MRI features and characteristics. Ultimately, the confirmation of diagnosis requires surgery. This retrospective study addresses MRI features including homogeneity of enhancement, margination, and associated syrinx in intramedullary astrocytomas (IMA) and ependymomas (IME) that assist in diagnosis and predict resectability of these tumors.
