Low-Grade Astrocytoma of the Tectal Region as an Unusual Cause of Knee Pain: Case Report

Abstract A 12-year-old boy was investigated for knee pain and contractures, and was found to have an intraspinal tumor of a lumbar nerve root and a tumor in the tectal region, both low-grade astrocytomas, We postulated that the tectal region astrocytoma metastasized to the lumbar intraspinal region. After surgery, the child underwent focal irradiation to the posterior fossa supplemented by craniospinal irradiation and a boost dose to the region of the lumbar spinal tumor. A low-grade astrocytoma rarely presents as spinal metastasis. This case may represent the first of a primary tectal low-grade astrocytoma manifesting as a symptomatic spinal mass.

Cranial Metastasis

OBJECTIVESolitary posterior fossa low-grade glial tumors (SPFLGT) in children are rarely associated with leptomeningeal dissemination (LMD). To date, there are no clear guidelines regarding the role of screening and surveillance spinal MRI (sMRI) in children with SPFLGT, at diagnosis or during follow-up periods. The current study reviews a cohort of children with SPFLGT, focusing on sMRI findings.METHODSIn this binational retrospective study, the authors analyzed 229 patients with SPFLGT treated and followed over 13 years. One hundred twelve children had at least 1 total sMRI screening or surveillance examination. One hundred seventeen had no sMRI, but did not present with clinical spinal signs or symptoms. Collected data included demographics, disease characteristics, radiology, pathology, and clinical follow-up data.RESULTSFor the 112 children with at least 1 sMRI, the mean duration from diagnosis to first sMRI was 11.73 ± 28.66 months (range 0–165 months). All sMRI scans were conducted as screening examinations, with no spinal-related symptoms. One patient was found to have a sacral intradural lesion concurrent to the brain tumor diagnosis. Over the course of 180 radiological and 533 clinical follow-up years for the 112 patients with sMRI, and 582 clinical follow-up years for the 117 patients with no sMRI, there were no additional cases with spinal tumor spread.CONCLUSIONSThe yield of screening sMRI in the absence of cranial metastasis, or spinal symptoms, is extremely low. Because preoperative sMRI is recommended for medulloblastomas and ependymomas, it may be logical to acquire. During the follow-up period the authors recommend limiting sMRI in patients without symptoms suggesting a spinal lesion, in patients without known cranial metastases, or recurrence or residual SPFLGT.

Intradural Extramedullary

Abstract BACKGROUND AND IMPORTANCE: Ependymomas are the most common primary spinal cord tumor, most frequently located near the cauda equina and conus medullaris. We believe that this is the first reported case of a low-grade, nonmyxopapillary (World Health Organization grade 2), intradural, extramedullary ependymoma involving a spinal nerve root. CLINICAL PRESENTATION: An 87-year-old woman presented with a chief complaint of acute onset of severe right hip and lateral thigh pain without midline back pain. She had baseline chronic bladder dysfunction, which remained unchanged. Her physical examination was significant for 4/5 strength in her right hip flexion (possibly related to pain), and 5 beats of clonus bilaterally. She had no point tenderness at the level of her compression fracture. Computed tomography of the patient's lumbar spine revealed a well-corticated, chronic compression fracture of the L3 vertebral body. Magnetic resonance images demonstrated an ovoid-shaped, 1.5 × 1-cm, well-circumscribed, intradural, extramedullary lesion at the conus medullaris. The patient underwent an L1-3 laminectomy with intradural resection of the mass, which was found to be intricately involved with a single nerve root. The nerve root was coagulated and sectioned, and a gross total resection of the tumor was achieved. CONCLUSION: The patient tolerated the procedure well, with no complications or any postoperative neurological deficit. Her right-sided pain immediately resolved after surgery. Her strength and ambulation were normal after surgery. No adjuvant radiotherapy was offered to the patient. This case illustrates a unique tumor presentation and the successful surgical treatment of the condition.
