“…On non-enhanced CT, SST manifests solid densities corresponding to cellularity, vascularity and distribution of collagenous or fibrous stroma, while the areas of necrosis or cystic degeneration exhibit low densities (7). The SSTs of the present 2 cases presented patchy areas of low attenuation.…”

In the present cases, following the administration of intravenous contrast material, the early enhancement of the outer region of the tumor was possibly due to the cellular area with numerous vascular spaces.…”

“…Microscopically, SST is characterized by cellular areas separated by hypocellular areas of densely collagenous, edematous or myxoid tissue and prominent vasculature, which creates a pseudo-lobular pattern (6,7). In a previous study, the cellular areas were observed to be composed of oval to spindle-shaped cells, with a single oval to round-shaped nucleus and a single prominent nucleolus (8).…”

Abstract. Sclerosing stromal tumor (SST) of the ovary, which was first described by Chalvardjian and Scully in 1973, is a rare ovarian neoplasm, occurring predominantly in young women. The most common clinical symptom in patients with SST is menstrual irregularities. Microscopically, the tumor is characterized by the presence of pseudo-lobulated cellular areas, with a prominent tendency to sclerosis, marked vascularity and pronounced variation in cellular size and shape. In the current study, 2 cases of SST of the ovary are presented. These cases were confirmed by imaging, surgical and histological examination. No adjuvant therapy was administered to the patients and the two patients were disease-free with no imaging findings of recurrence or metastasis 24 months following surgery.

“…Solitary fibrous tumor is seen as a sharply marginated round or oval mass. After administration of intravenous contrast material, large and often tortuous vessels may be seen along the periphery of solitary fibrous tumor on arterial phase contrast-enhanced images (Fig 4) (24). The tumor may show intense enhancement in the arterial phase and persistence of enhancement in the portal venous and delayed phases of contrast enhancement (25,26).…”

“…The tumor may show intense enhancement in the arterial phase and persistence of enhancement in the portal venous and delayed phases of contrast enhancement (25,26). The pattern of enhancement has been correlated to highly vascular cellular areas within the tumor (24). Cystic areas of degeneration and intratumoral necrosis may be present, such that the lesion resembles a GIST or leiomyosarcoma.…”

Soft-Tissue Sarcomas of the Abdomen and Pelvis: Radiologic-Pathologic Features, Part 2—Uncommon Sarcomas

Soft-tissue sarcomas occurring in the abdomen and pelvis are an uncommon but important group of malignancies. Recent changes to the World Health Organization classification of soft-tissue tumors include the movement of gastrointestinal stromal tumors (GISTs) into the soft-tissue tumor classification. GIST is the most common intraperitoneal sarcoma. Liposarcoma is the most common retroperitoneal sarcoma, and leiomyosarcoma is the second most common. GIST, liposarcoma, and leiomyosarcoma account for the majority of sarcomas encountered in the abdomen and pelvis and are discussed in part 1 of this article. Undifferentiated pleomorphic sarcoma (previously called malignant fibrous histiocytoma), dermatofibrosarcoma protuberans, solitary fibrous tumor, malignant peripheral nerve sheath tumor, rhabdomyosarcoma, extraskeletal chondro-osseous sarcomas, vascular sarcomas, and sarcomas of uncertain differentiation uncommonly arise in the abdomen and pelvis and the abdominal wall. Although these lesions are rare sarcomas and their imaging features overlap, familiarity with the locations where they occur and their imaging features is important so they can be diagnosed accurately. The anatomic location and clinical history are important factors in the differential diagnosis of these lesions because metastasis, more-common sarcomas, borderline fibroblastic proliferations (such as desmoid tumors), and endometriosis have imaging findings that overlap with those of these uncommon sarcomas. In this article, the clinical, pathologic, and imaging findings of uncommon soft-tissue sarcomas of the abdomen and pelvis and the abdominal wall are reviewed, with an emphasis on their differential diagnosis.

Imaging findings of solitary fibrous tumor in the abdomen and pelvis

Abstract: The possibility of SFT should be considered when a single or multiple masses with sharp border, inhomogeneous density or signal are detected, especially, with inhomogeneous intense enhancement in the arterial phase being maintained in the venous and delayed phases.
