Role of diffusion-weighted magnetic resonance imaging in the evaluation of scalp dermatofibrosarcoma protuberans.

Abstract:

BACKGROUND:Dermatofibrosarcoma protuberans (DFSP) is a rare tumor that grows with tentacle-like projections. In particular, on the scalp this could explain the frequent incomplete resections and the high rate of multiple local recurrences. Adequate pre- and postoperative imaging methods to visualize these prolongations are required to determine the extent of the tumor and to intercept recurrences in a short time base. METHODS:A retrospective study was performed on two cases of multiple recurrent scalp DFSP. The use of diffusion-weighted imaging (DWI) for pre- and postoperative assessment of DFSP was evaluated. RESULTS:Diffusion-weighted imaging magnetic resonance imaging was able to visualize the horizontal extent of tumor prolongations in the periosteum. Also, residual tumor tissue was distinguished from scar tissue in a large area of previous surgical interventions. CONCLUSION:We found DWI magnetic resonance imaging a valuable tool in planning the multidisciplinary therapeutic approach and follow-up of DFSP on the scalp.
