Rare presentation of inflammatory pseudotumour involving subcutaneous tissues with superficial fat sparing

Abstract

We present a unique case of inflammatory pseudotumour involving gluteal subcutaneous tissue with the sparing of superficial fat and report its contrast-enhanced CT, F-18 fluorodeoxyglucose positron emission tomography/CT and pathological findings. Although rare, inflammatory pseudotumours have been reported with a diverse spectrum of locations; however, the involvement of the subcutaneous tissue overlying the gluteal muscles with sparing of the most superficial fat has not been reported.

The Potential Utility of 18F-FDG PET/CT in Monitoring Corticosteroid Therapy in Inflammatory Pseudotumor

“…An end-of-treatment PET/CT showed complete metabolic response after 9 months of corticosteroid therapy (C). IPTs are very rare tumors, and the role of PET/CT has been reported only by a few cases published in the literature, [3][4][5][6][7][8][9] in which the patients were treated by surgery or intensity-modulated radiation therapy. There is no consensus with regard to the best treatment approach in IPT, the options ranges from surgical excision and/or radiotherapy, to chemotherapy or steroids.…”
