Journal Article
Two cases of primary cellular fibroblastic tumor of the ovary are described, which presented a challenging clinical and histopathological differential diagnosis of primary ovarian fibrosarcoma and ...
mitotically active cellular fibroma. On sonographic evaluation they both appeared as solid lesions with irregular margins, and on histological analysis both showed a count of 5–7 mitotic figures per 10 high‐power fields. Histopathological examination of the first case was characterized by the presence of hemorrhage, necrosis and severe nuclear atypia, with a metastatic peritoneal lesion, and the eventual diagnosis was primary ovarian fibrosarcoma. The second case, however, was diagnosed as a ‘mitotically active cellular fibroma’ owing to the lack of substantial severe cellular atypia, hemorrhage or necrosis. We speculate that ovarian fibrosarcoma at the preoperative examination might be considered in the differential diagnosis whenever a unilateral, heterogeneous, largely round solid ovarian lesion is detected.

The ‘lead vessel’: a vascular ultrasound feature of metastasis in the ovaries

Journal Article
Objective
To investigate, in a series of metastatic and primary invasive ovarian lesions examined by color Doppler, the prevalence of a main peripheral vessel penetrating into the central part of the ...
ovarian mass with a tree‐shaped morphology, defined as the ‘lead vessel’.
Methods
This was a retrospective study of 31 patients with histopathologically confirmed metastatic involvement of the ovary and 106 patients with confirmed primary invasive ovarian carcinoma, who had undergone standardized ultrasound examination, with established definitions of ultrasound characteristics. We retrieved sonographic images and videoclips, focusing on the detection of the lead vessel.
Results
The presence of the lead vessel was detected in 11/31 (35.4%) metastatic ovarian tumors, and in only two (0.01%) cases of primary ovarian carcinoma (P = 0.0001). At color Doppler analysis, metastatic ovarian lesions were characterized by significantly lower pulsatility index (P = 0.0001) and resistance index (P = 0.0001) values, and significantly higher peak systolic velocity (P = 0.0002) and time‐averaged maximum velocity (P = 0.04) values, when compared with primary ovarian carcinomas. The lead vessel was detected in 11/21 (52%) solid metastatic lesions and in no cases of multilocular or multilocular‐solid lesions (P = 0.008).
Conclusion
The lead vessel is a novel sonographic feature of vascular morphology in solid ovarian metastases. The more frequent observation of this feature in metastatic ovarian tumors compared with primary invasive ovarian carcinomas warrants further investigation in order to explore its potential role in the diagnosis of metastatic ovarian masses.
