Limited remodelling of expansile Ewing sarcoma after treatment.

Radiological findings of Ewing sarcoma have been well documented, and bone expansion or cystic change is known to be a relatively uncommon finding. On the other hand, expected changes in Ewing sarcoma after treatment have also been reported, e.g. regression of extraosseous soft tissue mass, regression and organization of the periosteal reaction, and remodelling of the lytic or sclerotic bone changes. However, remodelling of bone is often limited or incomplete. We saw an atypical change in Ewing sarcoma after treatment due to lack of significant remodelling of the expanding bone. Because such changes might be a cause of misdiagnosis, knowledge of it will help the radiologist in the follow up evaluation.

[Spontaneous frotobasal cerebrospinal fluid fistula].

After dealing in detail with the literature appeared since 1888, 3 observations by the author are discussed. These cases were congenital fissurations on the frontal base of the skull. Some cases developed clinical phenomena with increases of the intracranial pressure (convexity meningioma). The diagnosis is defined in a strict manner. All forms of direct arrorions by frontobasally located tumours or in combination with hyhpophyseal tumours as well as craniopharyngiomas are left out of consideration. They cannot be considered as spontaneous liquor fistulas. The well-known diagnostic and therapeutic measures are dealt with briefly.
