A 58-Year-Old Woman with Left-Sided Weakness and a History of a Pediatric Brain Tumor: A Case Report

Background

An uncommon but well-established complication of cranial irradiation is secondary neoplasm. This case presentation documents a radiation-induced malignant glioma 55 years after being diagnosed with “cerebral sarcoma,” now defined as atypical meningioma. This not only represents the longest reported latency period for a patient initially receiving over 30 Gy, but also provides a valuable historical perspective of neuro-oncology.

Clinical Presentation

A 58-year-old female presenting with progressive left-sided upper and lower extremity weakness with a past medical history significant for “cerebral sarcoma” was diagnosed with glioblastoma multiforme. This patient had previously been treated with resection and adjuvant radiation therapy via a 280-kVP orthovoltage machine and received 3,390 rad to the posterior three-quarters of the skull for “cerebral sarcoma.”

Conclusion

A comprehensive investigation of the past medical history helped uncover a mysterious pediatric diagnosis, helped drive the management 5 decades later, and serves as a reminder that seemingly safe interventions may still cause harm.

Primary spinal glioblastoma multiforme: A case report and review of the literature

RATIONALE

Primary spinal glioblastoma multiforme (GBM) is a rare clinical entity with an aggressive course and an invariably dismal prognosis. Its clinical characteristics, radiologic and pathologic findings, and treatment protocols have been discussed in a few cases.

PATIENT CONCERNS

A 15-year-old female was admitted to the neurology department with a chief complaint of progressive numbness and weakness in her left upper extremity for 3 months and neck pain for 1 month.

DIAGNOSES

Spinal magnetic resonance imaging showed an intramedullary expansile mass localized between C4 and C7. The diagnosis of GBM was determined on the basis of the histopathological findings after operation.

INTERVENTIONS

Laminotomy and laminoplasty between C4 and C7 were performed, and the tumor was partially resected. The patient was administered focal adjuvant radiotherapy concomitantly with oral chemotherapy following the surgery.

OUTCOMES

With severe neurologic deficits at 13 months after the diagnosis, the patient expired.

LESSONS

Although therapeutic options have been improving, the prognosis of the primary spinal GBM remains poor. The treatment of primary spinal GBM entered into a central registry and multiple-center cooperation is important in establishing future therapeutic strategies.

Radiotherapy-induced tumors of the spine, peripheral nerve, and spinal cord: Case report and literature review

BACKGROUND

The development of a secondary malignancy in the field of radiation is a rare but well-recognized hazard of cancer treatment. The radiotherapy-induced (RT-I) tumors are even more aggressive and potentially lethal than the primary tumor. To goal of this article is to report a case of RT-I neural tumor located in the peripheral nerve and spinal cord and to perform a literature review of the subject.

CASE REPORTS

Thirty-year male with symptoms of hypoesthesia and dysesthesia of the L5 nerve root distribution and previous treatment of a testicular seminoma 20 years previously. The lumbar magnetic resonance imaging showed the growth of a nerve root tumor. Surgery was performed, and a fusiform tumor was resected with clear margins. The anatomopathological and immunohistochemical studies were compatible with a malignant peripheral nerve sheath tumor. A total of 30 cases were included in the review. The mean age of the patients at diagnosis of the induced tumor was 39.36 (±16.74) years. Most were male (63.3%). The main type of primary disease was neural tumors (30%). The most common type of histology was fibrosarcoma (20.0%). No difference was found in age, gender, and time of diagnosis between neural and nonneural tumors. The mean survival after the diagnosis of the secondary tumor was 10.7 months (±13.27), and neural tumors had a longer survival period (P = 0.031).

CONCLUSION

The current gold standard therapy is complete resection with clear margins, since most tumors do not respond to chemotherapy and RT. The neural type of RT-I tumor presented a longer survival period.
