This case report demonstrates that hypofractionated partial-brain radiation therapy with limited margins is a reasonable approach following gross tumor resection of Ewing sarcoma metastases to the brain. The patient presented with 2 intracranial metastases treated with gross-total resection followed by radiation therapy to 30 Gy in 5 fractions. The patient experienced symptomatic treatment-related inflammatory changes with resolution after receiving dexamethasone. He remains alive at 21 months of follow-up with no evidence of disease.

Abstract Background Calvarial Ewing tumor is a relatively rare differential among bony neoplasms. We present our experience of managing primary calvarial Ewing sarcoma (EWS), highlighting their clinical and radiological findings. Method In a retrospective analysis, we evaluated our 12-year database for pathologically proven EWS. A literature search was conducted for the comparative presentation and update on the management and outcome. Result From January 2008 to December 2020, we managed eight patients (male:female = 5:3; age range 6 months to 19 years, mean 11.5 years) harboring primary calvarial EWS. All cases underwent wide local excision; two patients required intradural tumor resection, while one required rotation flap for scalp reconstruction. Mean hospital stay was 8 days. All patients received adjuvant chemo- and radiotherapy. Three patients remained asymptomatic at 5 years of follow-up, while two patients died. Conclusion Primary calvarial EWS is a rare entity. It usually affects patients in the first two decades of life. These tumors can be purely intracranial, causing raised intracranial pressure symptoms, which may exhibit rapidly enlarging subgaleal tumors with only cosmetic deformities or symptoms of both. Radical excision followed by adjuvant therapy may offer a favorable long-term outcome.

Abstract BACKGROUND As the outcome of pediatric brain tumors improves, late recurrence and radiation-induced tumor cases are more likely to occur, and the number of cases requiring re-irradiation is expected to increase. Here we report two cases performed intracranial re-irradiation after radiotherapy for pediatric brain tumors. CASE 1: 21-year-old male. He was diagnosed with craniopharyngioma at eight years old and underwent a tumor resection. At 10 years old, the local recurrence of suprasellar region was treated with 50.4 Gy/28 fr of stereotactic radiotherapy (SRT). After that, other recurrent lesions appeared in the left cerebellopontine angle, and he received surgery three times. The tumor was gross totally resected and re-irradiation with 40 Gy/20 fr of SRT was performed. We have found no recurrence or late effects during the one year follow-up. CASE 2: 15-year-old female. At three years old, she received 18 Gy/10 fr of craniospinal irradiation and 36 Gy/20 fr of boost to the posterior fossa as postoperative irradiation for anaplastic ependymoma and cured. However, a anaplastic meningioma appeared on the left side of the skull base at the age of 15, and 50 Gy/25 fr of postoperative intensity-modulated radiation therapy was performed. Two years later, another meningioma developed in the right cerebellar tent, and 54 Gy/27 fr of SRT was performed. Thirty-three months after re-irradiation, MRI showed a slight increase of the lesion, but no late toxicities are observed. CONCLUSION The follow-up periods are short, however intracranial re-irradiation after radiotherapy for pediatric brain tumors were feasible and effective.

Abstract BACKGROUND If new lesions are observed during follow-up of the malignant tumor after treatment, it is difficult to distinguish whether the tumor is a recurrent lesion, secondary cancer, or radiation necrosis of the brain. We have encountered a patient with symptomatic radiation necrosis of the cerebellum 16 years after treatment of medulloblastoma. CASE PRESENTATION: A 24-year-old man who had received a tumor resection and chemoradiotherapy for cerebellar medulloblastoma at the age of 8 presented with dizziness. For the past 16 years, there was no recurrence of the tumor. He subsequently underwent MRI scan, and T1-Gd image showed enhanced lesion in the right cerebellar peduncle. Cerebrospinal fluid cytology analysis was negative for tumor. We suspected tumor reccurence or secondary cancer, and performed lesion biopsy. The result of the pathological examination was radiation necrosis of the cerebellum. DISCUSSION: The interval of radiation necrosis of the brain and radiotherapy can vary from months to more than 10 years. So, whenever a new lesion is identified, radiation brain necrosis must be envisioned. According to guidelines in Japan, there is no absolute examination for discriminating tumor recurrence from radiation brain necrosis and diagnosis by biopsy may be required. CONCLUSION We experienced a case of symptomatic radiation necrosis of the cerebellum 16 years after treatment. In patients showing new lesion after long periods of time, the possibility of radiation necrosis to be considered.

Object In this paper, the authors' goal was to analyze the incidence, timing, and treatment of new metastases following initial treatment with 20-Gy Gamma Knife surgery (GKS) alone in patients with limited brain metastases without whole-brain radiation therapy (WBRT). Methods A retrospective analysis of 114 consecutive adults (75 women and 34 men; median age 61 years) with KPS scores of 60 or higher who received GKS for 1–3 brain metastases ≤ 2 cm was performed (median lesion volume 0.35 cm3). Five patients lacking follow-up data were excluded from analysis. After treatment, patients underwent MR imaging at 6 weeks and every 3 months thereafter. New metastases were preferentially treated with additional GKS. Indications for WBRT included development of numerous metastases, leptomeningeal disease, or diffuse surgical-site recurrence. Results The median overall survival from GKS was 13.8 months. Excluding the 3 patients who died before follow-up imaging, 12 patients (11.3%) experienced local failure at a median of 7.4 months. Fifty-three patients (50%) developed new metastases at a median of 5 months. Six (7%) of 86 instances of new lesions were symptomatic. Most patients (67%) with distant failures were successfully treated using salvage GKS alone. Whole-brain radiotherapy was indicated in 20 patients (18.3%). Thirteen patients (11.9%) died of neurological disease. Conclusions For patients with limited brain metastases and functional independence, 20-Gy GKS provides excellent disease control and high-functioning survival with minimal morbidity. New metastases developed in almost 50% of patients, but additional GKS was extremely effective in controlling disease. Using our algorithm, fewer than 20% of patients required WBRT, and only 12% died of progressive intracranial disease.

AbstractTorticollis refers to a condition in which the head is persistently tilted to one side, sometimes associated with pain. Torticollis in a child can be congenital or acquired. Torticollis as an initial manifestation of an underlying demyelinating syndrome is quite rare in children. Here, we report a 7-year-old girl who presented with persistent torticollis. Neuroimaging of the brain revealed features of a demyelinating disease. Further studies did not show any evidence of multiple sclerosis. Cerebrospinal fluid was negative for antiaquaporin-4 antibodies, antimyelin oligodendrocyte glycoprotein antibodies, and oligoclonal bands. A seronegative demyelinating disorder was considered. She was treated with pulsed methylprednisolone therapy. She responded well to steroids with no progression of illness during follow-up. Torticollis was partially improved.

AbstractMyxofibrosarcoma or myxoid malignant fibrous histiocytoma is one of the most common sarcomas of the limb. It is usually treated multimodally. Most frequent sites of metastasis are the bone, lung and lymph nodes. The present paper is a case report of a 65-year-old male with myxofibrosarcoma of the fibularis longus muscle, for which he first underwent surgery - tumor resection with appropriate margins. The tumor was staged pT2b cN0 cM0. Postoperative PET-CT revealed metabolically inactive pulmonary nodules. Two months after surgery, he underwent adjuvant radiotherapy, a total dose of 60 Gy and 6 courses of chemotherapy (doxorubicin and ifosfamide). Pulmonary nodules have been stationary on all subsequent imagistic studies. He is free of recurrence on long-term follow-up.
