“…Interestingly, our case is consistent with reports by Wang et al. 28 and Seo et al., 29 who stated that intratumoral flow voids on magnetic resonance images are a typical characteristic of SFTs. Most SFTs show serpentine flow voids, which are considered useful adjuncts in the differential diagnosis.…”

“…The intratumoral vessels in our case were displayed as the absence of signal (flow voids) on the enhanced T1-weighted axial images, which indicated that vessels had developed along with the mass.

“…Most SFTs show serpentine flow voids, which are considered useful adjuncts in the differential diagnosis. 28 , 29 Furthermore, the mass compressed adjacent anatomic structures, and the enhancement was progressively intense and heterogenous. The presence of an intratumoral area of low attenuation is correlated with the paucicellular fibrous components, which accumulate the contrast agent and display a persistent slightly centripetal enhancement pattern on delayed-phase images.…”

Solitary fibrous tumors (SFTs) are commonly seen in the pleura. SFT involvement of the vulva is rare, and clinical diagnosis is mainly based on histopathological and immunohistochemical analyses. We herein describe the imaging features of a 69-year-old woman with an SFT of the vulva. The SFT was hypointense on T1-weighted images, similar to muscle; however, it showed inhomogeneous hyperintensity predominantly on fat-suppressed T2-weighted images. An area of low signal intensity was evident on T2-weighted images, and the tumor showed progressive enhancement in delayed phases. The tumor also displayed heterogeneous and prolonged, persistent enhancement, and serpentine vessels were present in the peritumoral area as signal voids. Pathological examination confirmed that the lesion was an atypical SFT originating from the vulva, and it was composed of spindle cells and perivascular and stromal hyalinization. This case reveals the characteristic imaging findings of vulvar SFT and their association with the relevant pathological findings, thus contributing to the primary diagnosis and preoperative evaluation of this potentially aggressive tumor.

“…SFT/HPCs occasionally mimic meningioma but tend to lead to a worse overall prognosis and lower survival rate due to local recurrence and distant, extracranial metastasis [ 2 , 3 ]. The presence of bone erosion, absence of hyperostosis, sunburst flow void, and intratumoral calcification, and differing values of apparent diffusion coefficient have been proposed as radiological findings differentiating between meningiomas and SFT/HPCs [4] , [5] , [6] , [7] , [8] , [9] , [10] . In contrast, meningiomas accompanying bone erosion and SFT/HPCs with calcifications have also been reported [ 11 , 12 ].…”

“…15 As meningioma and SFT, usually originating from the dura mater, is an important differential diagnosis of intracranial hypervascular tumors with flow void sign. 16 Adjacent hyperostosis is a well-known imaging finding of meningioma, whereas bone destruction caused by SFTs would be attributed to a long-standing pressure effect.…”

Two cases of flow void sign of temporal bone metastasis from follicular thyroid carcinoma

et al. 2022

This report describes CT and MRI findings of temporal bone metastasis from follicular thyroid carcinoma in two cases. Both of these had large, osteolytic, hypervascular masses of the temporal bone, accompanied by internal scattered bone fragments and extraosseous mass formation on unenhanced and contrast-enhanced CT images. In the first case, several dilated and tortuous vessels within the markedly hypervascular mass were observed on the arterial phase of dynamic contrast-enhanced CT images. Compared with the signal intensity of the cerebellum, temporal bone masses showed slightly hypo- to slightly hyperintense on T1-weighted images and slightly hypo- to moderately hyperintense on T2-weighted images. Both cases had flow voids in abnormally dilated vessels within the mass on T1- and T2-weighted images. Thyroid follicular carcinoma rarely metastasizes the temporal bone and presents with an osteolytic hypervascular mass with flow void sign.
