Embolization of iatrogenic uterine pseudoaneurysm.

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.

CT, MRI and DWI Features of a Solid Organizing Hepatic Abscess.

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.

A presacral solitary fibrous tumor with extramedullary hematopoiesis: radiologic and pathologic findings.

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.

Pancreatoblastoma in an adult patient. A case report.

CONTEXT: Preoperative diagnosis of a pancreatoblastoma in adults is challenging because of its rarity. Furthermore, difficulties increase since pancreatoblastomas share radiological findings similar to those found in other masses of the pancreas. CASE REPORT: A 36-year-old woman was studied with ultrasonography and CT for a mass of the pancreatic head causing obstructive jaundice. Diagnosis of pancreatoblastoma was obtained with histology and immunohistochemistry of the resected specimen. CONCLUSION: We reviewed the radiological findings of pancreatoblastomas and possible radiological criteria of differentiation from other pancreatic tumors. A pancreatoblastoma should be considered in the differential diagnosis of a pancreatic mass presenting atypical radiological features.
