Functional Magnetic Resonance Imaging in Granulosa Cell Tumour of the Ovary: A Case Report

Granulosa Cell Tumour (GCT) is a rare malignant ovarian tumour. Adult GCT variety is more common than juvenile variety and occurs usually in postmenopausal women. It showed a spectrum of the imaging findings due to various histological appearances. It may present with solid masses, multilocular cystic lesion or completely cystic lesion. Here, authors present an interesting case of a 27-year-old young female, who presented with a large lump in the abdomen. On Magnetic Resonance Imaging (MRI) there was a large well-defined, multilocular cystic lesion at superior aspect of the lesion and complex cystic, solid mass at inferior aspect. Functional MRI like diffusion weighted imaging which provides good image contrast helped in determining the malignancy despite a benign diagnosis on ultrasound guided biopsy and furthering the patient for histopathological examination to come to a final diagnosis.
