Intestinal lipomatosis also known as lipohyperplasia is a rare disease. Diffuse infiltration of the fatty tissue mainly in the submucosal layer is characteristic. It is usually asymptomatic and found incidentally. We report a case of lipomatosis in the terminal ileum and ileocecal valve. Multidetector computed tomography (MDCT) with contrast enhancement showed fatty infiltration of the terminal ileum and ileocecal valve. [ABSTRACT FROM AUTHOR]

Purpose: The goal of the present study was to compare the patellar tendon cross-sectional area with the patellar tendon thickness and to determine the intra-observer compliance level in the cross-sectional area and thickness measurements. This comparison was used to describe the effects of playing volleyball on the patellar tendon., Materials and Methods: The patellar tendons of 60 volleyball players and 60 non-player female students, who were 11-16 years of age with similar physical characteristics, were examined using Doppler ultrasonography (US). Cross-sectional area and thickness measurements were conducted., Results: The proximal and distal thicknesses of the patellar tendon were similar, but the area was smaller for the distal portion. A correlation was observed between age and tendon thickness and between the thickness and area of the tendon. All of the measurements in the subjects with tendinosis were larger than those in the healthy controls. There were no pathological findings in the non-players. The intra-observer compliance was high., Conclusion: The transverse plane area measurement was as reliable as the thickness measurement and exhibited a high level of intraobserver compliance. This measurement can be conducted during routine examinations. The patellar tendons in the athletes were observed to be widened and thickened, most likely because of overuse. Patellar tendinosis and Osgood-Schlatter Syndrome may be asymptomatic and incidentally detected. Therefore, routine US examinations may help prevent further injuries. Although the tendon thicknesses were observed to be the same in both extremities, any observed difference in the tendon areas may alert the physician to a risk factor for the development of tendinosis.

Objective: The objective of our study was to evaluate the blood flow characteristics of the radial and ulnar arteries of the hands of patients with carpal tunnel syndrome (CTS) either in the neutral position or in provocative positions using color Doppler imaging., Subjects and Methods: Subjects with relevant complaints of CTS and positive Tinel sign and/or Phalen maneuver were recruited. Nerve conduction studies were performed to confirm the diagnosis of CTS. Forty-four hands of 22 patients with CTS (bilateral involvement) and 24 hands of 12 healthy volunteers were included in the study. Pulsed and color Doppler evaluations with the hands in the neutral, Phalen, and reverse Phalen positions were performed of the radial and ulnar arteries using a 5-13-MHZ linear-array transducer (Logiq 9)., Results: All of the CTS patients and control subjects were women; their mean ages were 50.77 ± 7.69 (SD) and 46.42 ± 4.32 years, respectively. When hands were evaluated in the neutral position, the flow volume, peak systolic velocity, end-diastolic velocity, and diameter values of both the radial and ulnar arteries were significantly greater in patients with CTS than in control subjects (all p < 0.05). When compared with the measurements obtained with hands at the neutral position, the decreases in the amount of blood flow during the Phalen and reverse Phalen maneuvers were significantly greater in the CTS group than the control group. The amount of blood flow decrease was not correlated with the disease duration., Conclusion: Blood flow in the hands of CTS patients differs from that of healthy individuals both at rest and during certain hand movements. Future studies, also with simultaneous monitoring of sympathetic innervation, could be beneficial to confirm the association between blood flow and the sympathetic nerves of the hand.

Objective: The objective of our study was to use Doppler sonography to detect the flow characteristics and parameters of the hand arteries that are needed to distinguish between primary Raynaud phenomenon (RP) and secondary RP., Subjects and Methods: The diameter, resistive index (RI), and flow volume of the digital, ulnar, and radial arteries of patients with primary RP and those with secondary RP were measured at rest and after cold provocation. The flow starting time in the digital artery and the flow normalizing time of all three arteries were also recorded after cold provocation., Results: At baseline and after cold provocation, the diameters of the radial and digital arteries and the flow volumes of the three arteries were less in patients with secondary RP than in primary RP patients. In primary RP and secondary RP, the flow normalizing times (mean ± SD) were 9.8 ± 3.88 and 25.88 ± 7.14 minutes, respectively, in the radial artery; 11.3 ± 7.43 and 32.15 ± 12.57 minutes in the ulnar artery; and 12.22 ± 6.82 and 32.67 ± 10.76 minutes in the digital artery. A flow normalizing time cutoff in the radial artery of 17 minutes yielded a sensitivity of 90% and specificity of 100%. A flow normalizing time cutoff in the ulnar artery of 23 minutes yielded a sensitivity and specificity of 71% and 100%, respectively. A flow normalizing time cutoff in the digital artery of 23 minutes yielded a sensitivity and specificity of 82.6% and 98%, respectively. The flow starting time of the digital artery was 3.80 ± 3.27 minutes in primary RP and 16.78 ± 9.97 minutes in secondary RP (p < 0.0001). The flow starting time cutoff of the digital artery was 7 minutes (sensitivity, 82.6%; specificity, 95.7%)., Conclusion: The diameter of the radial and distal arteries; flow volume; and flow volume normalizing time of the digital, ulnar, and radial arteries' flow starting time in the digital artery may be helpful in distinguishing between primary RP and secondary RP with high sensitivity and specificity values. These parameters may also facilitate objective follow-up of treatment. The noninvasive nature of Doppler sonography is an additional advantage, and there is no need for extra hardware or software.

Purpose: The aim of this prospective study was to determine the efficacy of three-dimensional computed tomography (3D-CT) and three-dimensional computed tomographic angiography (3D-CTA) that were reconstructed by using the axial images of the multiphasic helical CT in the preoperative evaluation of renal masses and demonstration of renal anatomy., Materials and Methods: Twenty patients that were suspected of having renal masses upon initial physical examination and ultrasonographic evaluation were examined through multiphasic helical CT. Two authors executed CT evaluations. Axial images were first examined and then used to reconstruct 3D-CT and 3D- CTA images. Number, location and size of the renal masses and other findings were noted. Renal vascularization and relationships of the renal masses with the neighboring renal structures were further investigated with 3D-CT and 3D-CTA images., Results: Out of 20 patients, 13 had histopathologically proven renal cell carcinoma. The diagnoses of the remaining seven patients were xanthogranulomatous pyelonephritis, abscess, simple cyst, infected cyst, angiomyolipoma, oncocytoma and arteriovenous fistula. In the renal cell carcinoma group, 3 patients had stage I, 7 patients had stage II, and 3 patients had stage III disease. Sizes of renal cell carcinoma masses were between 23 mm to 60 mm (mean, 36 mm). Vascular invasion was shown in 2 renal cell carcinoma patients. Collecting system invasion was identified in 11 of 13 renal cell patients. These radiologic findings were confirmed with surgical specimens., Conclusion: Three-dimensional CT and 3D-CTA are non-invasive, effective imaging techniques for the preoperative evaluation of renal masses.
