Intracranial aneurysm formation after radiotherapy for medulloblastoma

چکیده
BACKGROUND The development of an intracranial aneurysm after radiotherapy is rare but secondary effect of cranial irradiation in a primary disease treatment. CASE DESCRIPTION The patient was a 17-year-old male adolescent who was diagnosed as having a posterior fossa medulloblastoma when he was 8 years old. He had undergone tumor resection with radiotherapy and chemotherapy. A distal posterior inferior cerebellar artery aneurysm was identified by magnetic resonance imaging 8 years after radiotherapy and grew rapidly throughout the next 1 year. The patient underwent microsurgical clipping and was discharged without deficit. CONCLUSION This experience demonstrates that physicians caring for patients who have undergone intracranial radiotherapy should carefully consider the possibility of an aneurysmal formation when conducting follow-up imaging.

Intracranial calcification in survivors of childhood medulloblastoma.
Computerised tomography scans of the brain have been performed on 5 children who have survived at least 5 years after treatment with surgery and radiotherapy for medulloblastoma. Intracranial calcification of varying degrees of the basal ganglia and of the frontal and parietal cortex was detected in the 3 children who were irradiated under age 5 years.
متن کاملA case of adult onset medulloblastoma during maintenance chemotherapy for anaplastic astrocytoma one year after radiotherapy.
Multiple primitive intracranial tumors with different histological characteristics are uncommon. Although coexistence of a medulloblastoma with glial tumors has been reported in children, medulloblastoma is rarely found in adults, especially those older than 40 years of age. We present an extremely rare case of a medulloblastoma developing in a 40-year-old male undergoing maintenance chemothera...

BACKGROUND Delayed complications of radiation therapy comprise cerebral atrophy, radionecrosis and induction of tumors. Recent reports indicate the possibility of the "de-novo" formation of intracranial cavernomas in patients submitted to radiation therapy to the brain. OBJECTIVES To report three children, two with medulloblastomas and one with a pineal germinoma, treated with radiotherapy th...
متن کاملUpdate on molecular and genetic alterations in adult medulloblastoma
Medulloblastoma encompasses a group of aggressively growing cancers that arise either in the cerebellum or brain stem. They present primarily in children, with 80-85 % of medulloblastomas being diagnosed in patients of 16 years and younger. In adults, medulloblastomas are rare and account for less than 1 % of intracranial malignancies. Due to the low incidence of medulloblastoma in adults, the ...
متن کاملCushing's reflex in a rare case of adult medulloblastoma.
BACKGROUND Medulloblastoma is a primitive neuro-ectodermal tumor. It is common in childhood, but rarely seen at adult age, comprising only 1% of primary brain tumors. METHODS We treated a 31-year-old man presented to the emergency department (ED) with a chief complaint of nausea and vomiting for one week duration. Immediate frozen section revealed a grade IV medulloblastoma. During the hospit...
