Uterine artery pseudoaneurysms (UAPs) are rare vascular lesions that may be life threatening if not diagnosed and properly treated. The clinical presentation of UAPs includes a spectrum of symptoms that are often associated with other and more frequent gynecologic/obstetric pathologies, both with and without vaginal bleeding, and may span from postpartum hemorrhage to the absence of symptoms. We report cases of two patients with UAP, both of whom were diagnosed with ultrasonography and contrast-enhanced computed tomography and successfully treated with transcatheter embolization. The first patient presented delayed hypovolemic shock following surgery for endometriosis, whereas the second patient suffered from postpartum hemorrhage after cesarean section. Diagnosis of UAPs relies on noninvasive imaging; transcatheter arterial embolization is an effective treatment to control bleeding in both hemodynamically stable and unstable patients.

Solitary fibrous tumors (SFT) are rare, ubiquitous neoplasms of mesenchymal origin, with distinctive histopathological and immunohistochemical features. We herein report an unusual case of a presacral SFT diagnosed in an asymptomatic 40-year-old woman preoperatively investigated with computed tomography and magnetic resonance imaging. Post-operative pathology examination showed a SFT containing foci of extramedullary hematopoiesis. Revision of preoperative imaging did not evidenced any findings suggesting this unusual association. The patient was free from local recurrence and metastases one year after operation. Differential radiological and histological diagnoses of solid presacral masses is briefly discussed.

Solid organizing hepatic abscess is a rare form of focal infection, which needs differentiation from benign and malignant solid masses. We report a case of a 30-year-old man with a solid organizing hepatic abscess, diagnosed by imaging and ex juvantibus criteria. CT and MRI findings are presented and role of DWI is outlined. Noninvasive diagnosis of a solid organizing hepatic abscess is possible in the appropriate clinical setting; percutaneous or surgical biopsy may be indicated in equivocal cases.
