Pelvic Hydatid Disease: CT and MRI Findings Causing Sciatica

Pelvic masses, especially hydatid disease, rarely present with sciatica (1, 2). We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings

Multifocal peliosis hepatis: MR and diffusion-weighted MR-imaging findings of an atypical case

Peliosis is a rare benign disorder that is characterized by the presence of diffuse blood-filled cystic spaces and can occur in the liver, spleen, bone-marrow, and lungs. We present a 10-year-old boy with Fanconi anemia who presented with peliosis hepatis due to androgen treatment. Magnetic resonance (MR) imaging revealed multiple non-enhancing masses. Some of the lesions revealed fluid-fluid levels and extrahepatic extension on MR images. Diffusion-weighted (DW) imaging showed restricted diffusion. Fluid-fluid levels and extrahepatic extensions are unusual findings for hepatic peliotic lesions. In addition, DW imaging findings of peliosis hepatis have not been reported previously

Morphometric Assessment Of Corpus Callosum And Cerebral Hemispheres With Magnetic Resonance Imaging

Objective: In this study, our purpose was to assess the relationship between handedness, footedness and the morphological differences of certain intracranial structures on MR images. Material and Methods: 63 healthy male and 52 healthy female individuals were included in the study. In each subject, 16 measurements of intracranial structures were taken on MR images. Area of corpus callosum, also left and right cerebral hemispheres, length of CC, width of genu (r1), truncus (r2), isthmus (r3) and splenium of CC (r4) and width of corresponding cerebral hemisphere were measured. Results: There was a statistically significant difference in R3 (width of the corresponding cerebral hemisphere to r3) distance between those using their right feet and those using their left feet. Angle of genu in right-handed people was greater in males than in females. Angle of genu in cases using the left foot was greater in females than in males for standing on one leg. Conclusion: Morphometric assessment of CC with MR imaging related to handedness and footedness may be useful in demonstrating the relationship between callosal morphology, gender differences and extremity preference in neuroscience.Wo
