Nontraumatic hepatic artery pseudoaneurysm associated with acute leukemia: a possible complication of pyogenic liver abscess

Most hepatic artery pseudoaneurysms result from trauma, blunt or penetrating, such as that caused by percutaneous transhepatic procedures. We present a case of hepatic artery pseudoaneurysm resulting from a pyogenic liver abscess, which has not been described previously, in a patient with acute leukemia receiving chemotherapy.

Intraventricular Hemorrhage Caused by Lateral Ventricular Meningioma: A Case Report

Meningiomas causing intracranial hemorrhage are rare, and hemorrhage from a lateral ventricular meningioma seems to be even rarer. We report a case of trigonal meningioma in a 43-year-old woman who presented with intraventricular hemorrhage, and describe the CT, MRI and angiographic findings.

Magnetic resonance imaging of vaginal malignant melanoma

We report two cases of vaginal melanoma with magnetic resonance imaging findings. The first melanoma was a bilobular polypoid mass with melanotic and amelanotic components, which arose from the lateral wall of the vaginal canal. The melanotic melanoma showed high signal intensity (SI) on T1-weighted images and low SI on T2-weighted images, which was not suppressed by a fat-saturated sequence. Another melanoma showed a pale brown polypoid mass in the vagina, which revealed intermediate SI on T1-weighted images and high SI on T2-weighted images. On fat-suppressed images, both tumors were more clearly demonstrated with high SI.
