Abstract OBJECTIVE AND IMPORTANCE: Cranial fasciitis is a very rare, nontumoral lesion of the cranium with potential intracranial expansion typical of childhood. Radiotherapy has not been reported among the possible causes or factors associated with this condition. We present a case of cranial fasciitis in an 11-year-old patient previously admitted for cranial radiotherapy of a cerebellar medulloblastoma. Cytogenetic analysis revealed a pattern of chromosomal abnormalities suggestive of a radiation-induced lesion. CLINICAL PRESENTATION: An 11-year-old patient, who had been treated previously with craniospinal radiotherapy for a medulloblastoma, presented with a tumor resembling a parasagittal meningioma. INTERVENTION: At surgery, the tumor apparently had eroded the cranium and was deemed to originate from the external layer of the sagittal sinus. A distinct line of cleavage permitted total removal. Histological analysis was suggestive of cranial fasciitis. Cytogenetic analysis revealed the presence of a polyclonal karyotype in a background of nonclonal changes. CONCLUSION: Cranial fasciitis should be included in the differential diagnosis of intracranial tumors infiltrating the cranium. Treatment of these lesions is easier than that of other parasagittal lesions because the sinus is compressed but not infiltrated. This case is associated with previous radiotherapy; thus, cranial fasciitis could be considered one of the more common radiation-induced lesions.

Abstract

Abstract OBJECTIVE AND IMPORTANCE: Cranial fasciitis is a very rare, nontumoral lesion of the cranium with potential intracranial expansion typical of childhood. Radiotherapy has not been reported among the possible causes or factors associated with this condition. We present a case of cranial fasciitis in an 11-year-old patient previously admitted for cranial radiotherapy of a cerebellar medulloblastoma. Cytogenetic analysis revealed a pattern of chromosomal abnormalities suggestive of a radiation-induced lesion. CLINICAL PRESENTATION: An 11-year-old patient, who had been treated previously with craniospinal radiotherapy for a medulloblastoma, presented with a tumor resembling a parasagittal meningioma. INTERVENTION: At surgery, the tumor apparently had eroded the cranium and was deemed to originate from the external layer of the sagittal sinus. A distinct line of cleavage permitted total removal. Histological analysis was suggestive of cranial fasciitis. Cytogenetic analysis revealed the presence of a polyclonal karyotype in a background of nonclonal changes. CONCLUSION: Cranial fasciitis should be included in the differential diagnosis of intracranial tumors infiltrating the cranium. Treatment of these lesions is easier than that of other parasagittal lesions because the sinus is compressed but not infiltrated. This case is associated with previous radiotherapy; thus, cranial fasciitis could be considered one of the more common radiation-induced lesions.
