Intradural Extramedullary

ABSTRACTAstrocytomas of Conus‑Cauda equina region are rare. Astrocytomas, which are intramedullary tumors, may rarely have an extramedullary component. However, primary intradural extramedullary astrocytomas are extremely rare, with very few cases reported in the literature. We describe a giant extramedullary pilocytic astrocytoma of Cauda equina in a 20‑year‑old male. To the best of our knowledge, this is the first report of such a case in the available literature. This case highlights the fact that astrocytomas can be primarily extramedullary and emphasizes the need to consider pilocytic astrocytoma in the differential diagnosis of cystic Cauda equina tumors.

Extradural Space

Neoplasms of the spinal column and spinal cord, depending on their localization relative to the spinal cord and its membranes, are classified into extradural, intradural extramedullary and intramedullary. Extradural tumors are located outside the dura mater. This category includes tumors of the vertebral bodies and tumors lying in the extradural space of the spinal canal. Intradural extramedullary tumors are found within the dura but outside the spinal parenchyma. Intramedullary tumors originate within the spinal cord and are the rarest group of spinal tumors. The aim of the study is to determine the criteria for the differential diagnosis of studied pathology.

Considerable Experience

Although there has been considerable experience with anterior approaches to ventral intradural, extramedullary, and pial-based spinal lesions, there is no information in the literature regarding the safety and feasibility of the resection of an intramedullary tumor via an anterior approach. The authors report on the gross-total resection of an intramedullary cervical pilocytic astrocytoma via a C-7 corpectomy and anterior myelotomy. The surgery proceeded without complication, and postoperatively the patient maintained the preoperative deficit of mild unilateral hand weakness but had no sensory deficits. Follow-up MR imaging at 6 months showed gross-total macroscopic resection. Selected intramedullary tumors can be safely removed via an anterior approach. This approach avoids the typical sensory dysfunction associated with posterior midline myelotomy.

Technological innovations in spinal intradural tumor surgery simplify treatment. Surgical treatment of cranial benign and malignant pathologies under microscope with sodium (Na)-fluorescein guidance has often been reported, but few studies have focused on spinal intradural tumors. We aimed to investigate the usefulness of Na-fluorescein under yellow filter in intradural spinal tumor surgery by retrospectively reviewing cases involving intramedullary and extramedullary tumors operated under the guidance of Na-fluorescein. Forty-nine adult patients with a diagnosis of spinal intradural tumor operated under a yellow filter (560 nm) microscope using Na-fluorescein dye were included in the study. Demographic data, such as age and sex, neurological status, extent of tumor resection, histopathological diagnosis, Na-fluorescein staining pattern, and its usefulness during surgery were noted and statistically analyzed. Of all recruited patients, 26 women (53.1%) and 23 men (46.9%), were included for analysis. The age range of the patients was 18–64 years, with a mean age of 41.6 ± 13.9. An intradural intramedullary mass was found in 30.6% (n = 15) of the patients, and an intradural extramedullary mass in 69.4% (n: 34). While Na-fluorescein staining was homogeneous in all intradural extramedullary tumors, 73.3% (n: 11) of intradural intramedullary tumors were homogeneous, and 13.3% (n: 2) moderately heterogeneous. In the whole study group, the Na-fluorescein staining pattern was helpful in surgical resection in 47 cases (95.9%). While 34/34 (100%) found it helpful for extramedullary tumors, 13/15 (86.7%) did in intramedullary tumors, and for 2/15 (13.3%) it was not. In conclusion, Na-fluorescein helps in distinguishing tumor from healthy tissue in intradural extramedullary and intramedullary tumor surgery under a yellow filter microscope in most cases, thus providing convenient assistance to surgeons.

Due to its rarity, a complete understanding of the clinical behavior, pathogenesis, and diagnostic definition of anaplastic pilocytic astrocytoma (APA) is currently lacking. The optimal clinical management and use of adjuvant therapies has yet to be defined. We present a 64 year-old-female with progressive headaches, dysarthria, and ataxia, who was found to have right cerebellar mass. A gross total resection was achieved through two staged operations. Pathology demonstrated focal areas of necrosis, tumor infiltration, and increased mitotic activity most consistent with APA. Adjuvant chemotherapy and stereotactic radiosurgery were administered. Approximately two years later, the patient presented with symptoms of cauda equina syndrome, and lumbar spine imaging demonstrated a large intradural mass at the conus medullaris with diffuse leptomeningeal enhancement. A biopsy was performed and was consistent with metastatic APA. APA may rarely progress to metastatic disease, most frequently involving the leptomeninges of the posterior fossa and cervical spine. This report represents the first case of metastases distal to the cervicomedullary junction.

Plasmacytomas are solitary tumours characterized by neoplastic proliferation of plasma cells and can be found isolated or in associated with multiple myeloma. Plasmacytomas uncommonly occur intracranially, and dural plasmacytomas without involvement of the calvarium are exceedingly rare. Reported cases indicate durally-based plasmacytomas mimick the appearance of meningioma, lymphoma or sarcoma of the dura. The authors report a case of a 77-year-old male with known multiple myeloma who presented with a 3-week history of confusion, speech impediment, and right sided weakness. A non-contrast CT scan revealed a dense extra-axial mass in the left frontal lobe with initial concerns of an extra-axial hemorrhage. A subsequent MRI demonstrated a contrast enhancing mass with a broad-based dural tail and no underlying calvarial lesion. Differential diagnosis included meningioma or intracranial plasmacytoma. The patient underwent surgical resection and was found to have intratumoural hemorrhage, with pathology confirming plasmacytoma. In the published literature, there are only 20 prior reports of dural plasmacytomas (with and without primary calvarial infiltration), of which only five previous cases reported associated intratumoural hemorrhage. Our case, along with this literature, suggests that new onset of focal neurologic deficits in patients with a history of multiple myeloma merits careful investigation, and that intracranial plasmacytoma should be considered on the differential diagnosis even when imaging reveals masses consistent with hemorrhage or meningioma.

Primary synovial sarcoma originating from the cauda equina is extremely rare. Only one case, involving an 11-year-old girl, has been reported. The authors describe the case of a 23-year-old woman with a primary synovial sarcoma of the cauda equina. The patient visited a local hospital and described a 2-month history of low-back pain. She was referred to the authors' hospital for further evaluation. On physical examination, she had a straight–leg raising result of 70° bilaterally. Motor examination revealed Grade 4/5 strength in the bilateral extensor hallux longus muscles. There was normal sensation to light touch and vibration in the lower extremities. Sagittal Gd-enhanced T1-weighted MR imaging demonstrated an intradural, extramedullary, and uniformly enhancing mass that extended from L-3 to L-4. The mass was totally resected and adjuvant local radiation therapy was administered. Reverse transcriptase polymerase chain reaction (RT-PCR) of a paraffin-embedded tissue sample revealed SYT-SSX fusion transcripts, and the diagnosis of synovial sarcoma was confirmed. Five and a half years after surgery, the patient is free of local recurrence and metastatic disease. The RT-PCR detection of SYT-SSX fusion transcripts played a key role in establishing the diagnosis of synovial sarcoma of the cauda equina. Complete resection of the mass with adjuvant local radiation therapy proved to be effective.
