Using contrast-enhanced ultrasound to guide a successful biopsy of a splenic sarcomatoid carcinoma.

Introduction: Splenic lesions are uncommon and frequently cause a diagnostic dilemma, often with non-specific findings on both ultrasound and cross-sectional imaging with histological confirmation necessary. To reduce patient morbidity, primarily from haemorrhage and to increase diagnostic yield, precise imaging and biopsy targeting are needed.

Case: We present a case of an indeterminate complex splenic lesion, with areas of necrosis which required histological diagnosis.

The middle interhemispheric variant of holoprosencephaly: magnetic resonance and diffusion tensor imaging findings.

Objective: The middle interhemispheric (MIH) variant of holoprosencephaly (HPE) is the incomplete separation of midline cerebral hemispheres with the absence of callosal body. We aimed to describe the additional knowledge of diffusion tensor imaging (DTI) over conventional MRI in the evaluation of patients with MIH variant of HPE.

Methods: Conventional MRI and DTI data of five patients were retrospectively evaluated.

Carotid Doppler ultrasound evaluation in patients with pulsatile tinnitus.

A wide range of conditions, including atherosclerosis, may lead to pulsatile tinnitus. The objective of this study was to evaluate the patients with pulsatile tinnitus by means of carotid Doppler ultrasound parameters. Thirty-four patients with pulsatile tinnitus were enrolled in the study.
