REGRESSION OF METASTATIC NEUROBLASTOMA TO GANGLIONEUROMA

The spontaneous regression of neuroblastoma to ganlioneuroma is a rare occurrence. Reviewing the literature, we found no more than 12casesreported.'•2.9.,o.'4.1s We report a case of metastatic neuroblastoma of multifocal skeletal and soft tissue areas with gross deformities which regressed to ganglioneuroma, with good prognosis.

Spontaneous radiographic resolution and subsequent redemonstration of an untreated glioblastoma.

The authors present the first case of spontaneous radiographic resolution and subsequent redemonstration of Gd enhancement of an untreated glioblastoma. They also review the literature on MR imaging enhancement patterns of high-grade gliomas and speculate that this phenomenon could be attributed to the dynamic biology of glioblastomas but could also represent pseudoregression following successf...

Spontaneous Regression of an Incidental Spinal Meningioma

AIM The regression of meningioma has been reported in literature before. In spite of the fact that the regression may be involved by hemorrhage, calcification or some drugs withdrawal, it is rarely observed spontaneously. CASE REPORT We report a 17 year old man with a cervical meningioma which was incidentally detected. In his cervical MRI an extradural, cranio-caudal contrast enchanced lesio...
