Hepatocellular carcinoma presenting as a huge intra-abdominal mass: a case report.

Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver and is generally associated with hepatitis B or C virus-related cirrhosis. A giant intra-abdominal HCC mass that fills nearly the whole abdomen is not often reported in the literature. In this report, we present a case in which a patient with hepatitis B developed a giant intra-abdominal mass that originated from segment three of the liver and infiltrated the stomach and transverse colon.

Comparison of the diagnostic performances of diffusion parameters in diffusion weighted imaging and diffusion tensor imaging of breast lesions.

Purpose: To evaluate the diagnostic efficiency of the diffusion parameters measured by conventional diffusion-weighted imaging (DWI) and diffusion tensor imaging (DTI) for discrimination of malignant breast lesions from benign lesions and the normal breast.

Materials And Methods: The study included 52 women with 55 breast lesions (30 malignant, 25 benign). DTI and DWI were performed complementary to dynamic contrast MRI at 3T.

A rarely seen fistula between coronary artery-descending aorta in a patient with coarctation of aorta and bicuspid aortic valve stenosis.

Congenital heart diseases may be seen isolated as well as in conjunction with other anomalies. Coarctation of aorta forms 6-8% of all congenital heart diseases. Most commonly, it is seen in conjunction with bicuspid aortic valve.

The role of preoperative radiological assessment of vascular injury on surgical decision making in mutilating injuries of the upper extremity.

Preoperative assessment of the extent of vascular injury is important in patients with mutilating injuries of the upper extremity. The aim of this report was to discuss the influence of computed tomography angiography (CTA) and digital subtraction angiography (DSA) on the operating room decision-making in mutilating injuries and limb-salvage procedures of the traumatic upper extremity. Four DSA and 3 CTA were performed in 7 patients with a mean age of 28.

Diffusion weighted MR imaging in the differential diagnosis of haemangiomas and metastases of the liver.

Background: The purpose of the study was to evaluate the value of diffusion-weighted imaging in the differential diagnosis of haemangiomas from metastases of the liver. PATIENTS AND METHODS.: We analyzed 69 lesions in 38 patients (33 haemangiomas; 36 metastases) in the retrospective study.

Lower gastrointestinal bleeding, hematuria and splenic hemangiomas in Klippel-Trenaunay syndrome: a case report and literature review.

Klippel-Trenaunay syndrome is a congenital vascular anomaly characterized by a triad of varicose veins, cutaneous capillary malformation, and hypertrophy of bone and soft tissue. Gastrointestinal and genitourinary vascular malformations in Klippel- Trenaunay syndrome may present with lower gastrointestinal bleeding and hematuria. The majority of patients with splenic hemangiomatosis are asymptomatic.

Color Doppler ultrasonographic flow parameters in the differentiation of benign and malignant causes of omental thickening.

Objective: The purpose of the study was to determine if color Doppler ultrasonographic (US) quantitative flow parameters are valuable to differentiate malignant peritoneal or omental involvement from benign causes.

Materials And Methods: Twenty-six consecutive patients with peritoneal or omental thickening detected by gray scale US, computed tomography, and magnetic resonance underwent color Doppler US examinations. All the Doppler signal waveforms were recorded, and resistive (RI) and pulsatility indices (PI) were calculated automatically by the US machine.

Gender and the lateral angle of the internal acoustic canal meatus as measured on computerized tomography of the temporal bone.

Introduction: Cadaveric studies yielded promising results in sexing the temporal bones by measuring the lateral angle of the internal acoustic canal meatus. In this study, we evaluated the capability of computerized tomography of the temporal bone to reproduce these results.

Methods: Lateral angle of the internal acoustic canal meatus was measured in 92 patients (47 females and 45 males) on axial slices of high resolution computerized tomography scans of the temporal bone.

Diffusion-weighted imaging in the differential diagnosis of simple and hydatid cysts of the liver.

Objective: The purpose of our study was to evaluate the value of diffusion-weighted imaging (DWI) in the differential diagnosis of simple and hydatid cysts of the liver, particularly in the completely liquid type of hydatid cyst.

Subjects And Methods: Eighty-two cysts (43 simple cysts, 39 hydatid cysts) were included in this prospective study. DWI was performed using a breath-hold single-shot echo-planar spin-echo sequence, and apparent diffusion coefficients (ADCs) were calculated.

Popliteus muscle sesamoid bone (cyamella): appearance on radiographs, CT and MRI.

Popliteus muscle sesamoid bone, also known as cyamella, is an accessory ossicle that is located in the vicinity of the proximal musculo tendinous junction. While commonly seen in small mammals such as cats and dogs, its presence in humans is very rare. In this report, we present the radiological findings of the popliteus muscle sesamoid bone, incidentally detected in a 47-year-old male.

Driven equilibrium (drive) MR imaging of the cranial nerves V-VIII: comparison with the T2-weighted 3D TSE sequence.

Purpose: The aim of this study is to evaluate the efficacy of the driven equilibrium radio frequency reset pulse (DRIVE) on image quality and nerve detection when used in adjunction with T2-weighted 3D turbo spin-echo (TSE) sequence.

Materials And Methods: Forty-five patients with cranial nerve symptoms referable to the cerebellopontine angle (CPA) were examined using a T2-weighted 3D TSE pulse sequence with and without DRIVE. MR imaging was performed on a 1.

Conservative treatment of giant abdominal wall hematoma.

A fifty-seven-year-old male patient on warfarin therapy presented to the emergency department with severe abdominal pain that had started after a cough episode and persisted for four days. Ultrasonography showed an extensive hematoma, 17x14x7 cm in size, but failed to determine whether it was located intra-abdominally or in the abdominal wall. Computed tomography confirmed the diagnosis of abdominal wall hematoma (25x21x10 cm).
