Irregular hypoechoic masses in the breast do not always indicate malignancies. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient's symptoms and personal history. Careful ultrasonographic examination and biopsy could help to differentiate these from malignancies.

Testicular lymphoma is an uncommon testicular tumor that usually presents as a painless mass. It usually shows hypervascularity on color Doppler ultrasound (US) and a mild enhancement on enhanced CT or MRI. We present an unusual case of a testicular lymphoma mimicking a missed testicular torsion in a 67-year-old male patient with right scrotal swelling and intermittent pain for 2 months. Color Doppler US demonstrated the absence of vascularity in the enlarged right testis, and the initial diagnosis was a missed testicular torsion. CT demonstrated a poorly enhancing mass rather than a missed testicular torsion with enhanced small nodular foci at the periphery. The final pathological diagnosis was testicular lymphoma.

The treatment of portal vein thrombosis (PVT) in patients with liver cirrhosis (LC) has been controversial, and it is generally caseand institution-dependent. The occurrence of acute or extensive PVT is critical and requires urgent treatment because it is usually accompanied by symptoms, particularly when total occlusion occurs, causing acute decompensation of liver disease. Even in severe cases, drug selection and treatment duration are determined based on each institution’s experience. Therefore, consistent guidelines for the treatment of patients with LC with PVT are required. Recently, a patient with acute occlusive PVT with LC who showed signs of acute decompensation was treated by administering low molecular weight heparin as anticoagulant therapy. After anticoagulant treatment, the portal vein was almost completely recanalized, and the deteriorated liver function improved. In addition, the patient recovered well and showed no recurrence of PVT for more than a year. Thus, the most recent knowledge regarding the treatment of nonmalignant PVT in LC was reviewed along with a case report.

Desmoplastic small round cell tumor (DSRCT) is a rare and aggressive malignancy common in young male patient. Typical imaging features of DSRCT include multiple soft tissue masses in the peritoneal cavity, omentum, or mesentery without an organ of origin. This report presents a rare manifestation of DSRCT revealing a solitary large retroperitoneal mass with hepatic metastasis and malignant portal vein thrombosis in 70-year-old women together with the review of literature. The tumor showed a hemorrhagic and necrotic mass with peripheral portion of T2 hypo-intensity and delayed enhancement that indicated desmoplastic stroma with dense cellularity.

Inflammatory myofibroblastic tumor (IMT) is an uncommon soft tissue tumor mimicking malignancy, which can be found in any part of the body. However, IMT involving the prostate is extremely rare. Previous reports on prostatic IMTs mainly focused on the pathological and immunohistochemical findings of the tumor and they lacked radiological findings. This report presents a case of prostatic IMT in a 60-year-old man who presented with voiding difficulty and elevated prostate-specific antigen (PSA) level. On magnetic resonance imaging, a hypointense mass was observed on T2-weighted images with broad and extensive extracapsular extension, showing diffusion restriction, early well enhancement and delayed mild washout, which could mimic prostate cancer. On needle biopsy of the prostate mass, cancer cells were not detected; and a benign tumor was suspected with a normalized PSA level. Finally, prostatectomy was performed to rule out prostate cancer; and prostatic IMT was confirmed on histopathologic examination.

Primary mesenteric liposarcoma is rare. It is difficult to make an accurate preoperative diagnosis of the myxoid type of liposarcoma by using imaging such as ultrasound or computed tomography (CT) due to the very small amount of fat that is located in the tumor. We report a case of primary myxoid liposarcoma of the mesentery which was difficult to differentiate from other solid mesenteric tumors with a myxoid component such as low grade fibromyxoid sarcoma, myxoid leiomyosarcoma or myxoma. Use of chemical shift magnetic resonance (MR) imaging to detect small fat components and its cystic appearance with solid components on the MR images can be useful to differentiate myxoid liposarcoma from the other mesenteric tumors with a myxoid component.

Viagra has been prescribed worldwide to treat men with erectile dysfunction. Clinical trials have shown that Viagra may cause various kinds of adverse effects include some central nervous system (CNS) adverse effects. Although extremely rare, toxic encephalopathy also can be one of those effects. This report presents a case of encephalopathy caused by Viagra in correlation with its radiologic findings. Its pharmacologic mechanism and potential effects on the biochemistry of the CNS are reviewed.
