“…On MRI, SFT shows intermediate signal intensity on T1-weighted images and heterogeneous signal on the fat-saturated T2-weighted images. The hypointense areas on the T2 images correlating with fibrous or sclerotic tissue [20] , [21] and the T2 hyperintense areas correspond to the more cellular, myxoid areas or cystic changes [22] , [23] , [24] . Following contrast administration enhancement pattern depends on the histologic factors like cellularity and the amount of fibrous or myxoid tissue.…”

Solitary fibrous tumors are primary mesenchymal tumors, which may occur in any part of the body. Overall, these tumors are considered to have intermediate malignant potential with 5- and 10-year metastasis-free and overall disease-specific survival rates of 74% and 55%, and 89% and 73%, respectively (Demicco et al, 2012). Herein we present an unusual case of solitary fibrous tumors involving the ischioanal fossa in a 19-year-old woman with radiologic-pathologic correlation. This case was complicated by extensive tumor vascularity and was thus managed with preoperative embolization followed by en bloc surgical resection.

“… 1 , 2 , 7 On CT scanning, SFT shows a pattern of heterogeneous contrast enhacement as a mass that can envelop the kidney. 7 , 8 Magnetic resonance imaging (MRI) of solitary fibrous tumor of the retroperitoneum demonstrates a signal isointense to muscle on T1-weighted sequences, a heterogeneous hypointense signal on T2 sequences and significant uptake after gadolinium injection. These imaging characteristics of solitary fibrous tumor of the retroperitoneum are very similar to those described for this tumor in a pleural location.…”

Solitary fibrous tumor is an uncommon neoplasm affecting adults and typically located in the pleura and can also occur in a large number of other extra thoracic sites. We present the case of a solitary fibrous tumor (SFT) of the retroperitoneum and describe their histopathological and immunohistochemical features. The identification of SFT in the retroperitoneum is of importance because its clinico-pathological behaviour is still unclear. The pathologist plays a fundamental role in establishing both the positive and differential diagnosis.

“…SFTs on imaging display hypervascular signalling on contrast-enhanced CT. T1-weighted MR shows intermediate signalling, with flow voids on T2-weighted imaging due to dense collagen and fibrosis [53]. Intense enhancement is seen after administration of gadolinium contrast material [78]. …”

The perinephric space, shaped as an inverted cone, sits between the anterior and posterior renal fasciae. It can play host to a variety of clinical conditions encountered daily in the reporting schedule for a radiologist. Lesions may be classified and diagnosed based on their imaging characteristics, location and distribution. A broad range of differential diagnoses can be attributed to pathology sitting within this space, often without clinical signs or symptoms. An understanding of commonly encountered conditions affecting the perinephric space, along with characteristic imaging findings, can illustrate and often narrow the likely diagnosis. The aim of this essay is to describe commonly encountered neoplastic and non-neoplastic entities involving the perinephric space and to describe their key imaging characteristics.Teaching Point• Despite often a bulky disease, perinephric lymphoma does not produce obstruction or stenosis.• In primarily fatty masses, defects within the renal capsule likely represent angiomyolipoma.• Consider paraganglioma if biopsy is planned; biopsy may lead to catecholamine crisis.
