Leiomyosarcoma of the Inferior Vena Cava Confirmed by Aspiration Biopsy With a Catheter During Digital Subtraction Angiography

Leiomyosarcoma of the vascular origin is a rare malignant tumor. It originates from the smooth muscle cells of the media with intra- or extraluminal growth, and in most cases it arises in the inferior vena cava. The diagnosis is often delayed because the clinical symptoms of this disease are often nonspecific. Accurate diagnosis of inferior vena cava leiomyosarcoma (IVCLMS) needs histologic confirmation. We report a case of IVCLMS histologically confirmed by aspiration biopsy with a catheter during digital subtraction angiography presenting with pulmonary emboli in a 65-year-old man

Whole-Body MRI Screening in Asymptomatic Subjects; Preliminary Experience and Long-Term Follow-Up Findings

BACKGROUND: The aim of this study is to describe the technique and to evaluate the results of whole-body magnetic resonance imaging in an asymptomatic population. MATERIAL AND METHODS: Between March 2009 and December 2011, 118 consecutive subjects undergoing thorough medical check-up were prospectively included in the study. MRI was performed with a 205-cm moving table, parallel imaging and automatic image composing software. RESULTS: In 83 subjects (70%), 103 benign lesions were detected. Two malignant (adrenal and renal carcinoma) lesions and one precancerous (pancreatic mucinous carcinoma) lesion were detected. The most common lesions were renal cysts, liver hemangiomas, liver cysts, thyroid nodules, and uterine leiomyomas. CONCLUSIONS: WB-MRI is able to cover area from head to toes in one diagnostic work-up, and besides the anatomic regions evaluated by conventional radiological modalities, i.e. brain parenchyma, bones and extremities, can be evaluated in one examination

Combined Aplasia of Sphenoid, Frontal, and Maxillary Sinuses Accompanied by Ethmoid Sinus Hypoplasia

Objective: To report the case of a woman who had combined aplasia of sphenoid, frontal, and maxillary sinuses accompanied by ethmoid sinus hypoplasia

Limbic Encephalitis in Association with Systemic Lupus Erythematosus: A Case Report

Limbic Encephalitis (LE) is a syndrome manifesting with seizures and delusions, progressive memory loss, and behavioral abnormalities lasting for weeks. Systemic Lupus Erythematosus (SLE) is a chronic autoimmune connective tissue disease that can affect any part of the body. Central nervous system (CNS) involvement has been reported in 14-75% of SLE cases. We present the clinical, immunological, and radiological features of a case of LE occurring in association with SLE.

A rare case of paratesticular leiomyoma in a child

Leiomyomas are benign, slow-growing, smooth muscle tumors, which can occur at many locations in the body. The male genitourinary tract is seldom affected and scrotal leiomyomas are extremely rare. Most of the scrotal leiomyomas are localized in the testis, epididymis, spermatic cord, subcutaneous tissue, tunica albuginea, and scrotal skin and only a few of them are reported in the origin of isolated tissue without paratesticular structures in the paratesticular region. We are presenting a case of solitary paratesticular leiomyoma in a child, which is very rare in terms of lesion location and patient age, and describing the imaging features of this lesion

Micro-dose Paranasal Computed Tomography is Valuable When Evaluating Diseases of the Paranasal Sinuses

Aim: We explored whether a reduction in the radiation dose affected the quality of diagnostic images generated using third-generation dual-source computed tomography (CT) running advanced third-generation iterative reconstruction software

Atypical pyogenic brain abscess evaluation by diffusion-weighted imaging: diagnosis with multimodality MR imaging

Whether a brain abscess is apparent by imaging depends on the stage of the abscess at the time of imaging, as well as the etiology of the infection. Because conventional magnetic resonance imaging (MRI) is limited in its ability to distinguish brain abscesses from necrotic tumors, advanced techniques are required. The management of these two disease entities differs and can potentially affect the clinical outcome. We report a case having atypical imaging features of a pyogenic brain abscess on advanced MRI, in particular, on diffusion-weighted and perfusion imaging, in a patient with osteosarcoma undergoing chemotherapy
