RESUMEN

Anomalous systemic arterial supply to the lungs with normal bronchial branching and pulmonary arterial supply is an unusual variant of the sequestration spectrum. Pseudosequestration is referred as the combination of systemic arterial supply to lung with normal bronchial connection. Thorax computed tomography (CT) and CT angiography are non-invasive and useful techniques in making the definitive diagnosis. Herein, we report two paediatric patients with anomalous systemic arterial supply to normal basal segments of the lower lobes.

RESUMEN

A 5-year-old girl was admitted to our hospital due to fatigue and fever lasting for six months. She had systolic murmur in the mesocardiac and apex regions and hepatosplenomegaly. Laboratory evaluation revealed leukocyte and eosinophil counts of 176 and 144.32 x 10(9)/L, 3.4% blasts in bone marrow and monosomy 8. She developed pulmonary, cardiac, nervous system, ocular and bone involvement. Upon diagnosis of "chronic eosinophilic leukemia, not otherwise specified" (WHO 2008 classification), she received methylprednisolone, vincristine, cytarabine and 6-thioguanine. After hematopoietic stem cell transplantation from a full-matched sibling was performed, the patient expired due to graft failure and septicemia.

RESUMEN

Spleen can have a wide range of anomalies including its shape, location, number, and size. Although most of these anomalies are congenital, there are also acquired types. Congenital anomalies affecting the shape of spleen are lobulations, notches, and clefts; the fusion and location anomalies of spleen are accessory spleen, splenopancreatic fusion, and wandering spleen; polysplenia can be associated with a syndrome. Splenosis and small spleen are acquired anomalies which are caused by trauma and sickle cell disease, respectively. These anomalies can be detected easily by using different imaging modalities including ultrasonography, computed tomography, magnetic resonance imaging, and also Tc-99m scintigraphy. In this pictorial essay, we review the imaging findings of these anomalies which can cause diagnostic pitfalls and be interpreted as pathologic processes.

RESUMEN

OBJECTIVE: Pigment epithelium-derived factor (PEDF) has anti-angiogenic, immunomodulatory and anti-inflammatory properties. In addition to the significant role it plays in reducing diabetic complications, PEDF is now used in the treatment of certain cancers. It possibly plays a role in insulin resistance cases, too. However, whether metformin treatment has any significant effects on PEDF levels is not known. In this study, we investigated the regulation of PEDF in type 2 diabetes in relation to fat mass and insulin resistance before and after the use of metformin for treatment. DESIGN: Prospective cohort study. SUBJECTS: Thirty-six patients with newly diagnosed type 2 diabetes and 33 healthy individuals. MEASUREMENTS: Baseline weight, waist circumference (WC), fasting (FPG) and postprandial (PPPG) glucose, insulin, HbA1c, HOMA, PEDF and total/truncal fat mass were determined both in the diabetic and control subjects. Procedures were repeated in the diabetic group after a 6-month metformin treatment. RESULTS: Baseline FPG, PPPG, HbA1c, HOMA, weight, WC and truncal fat mass were higher in patients with diabetes whereas PEDF levels were found to be comparable with the controls. We completed the study with 31 of the 36 patients with diabetes we had selected for the study. We observed a decrease in the weight, WC, FPG, PPPG, HOMA, total and truncal fat mass of the patients while there was a significant rise in the PEDF levels (P = 0·002) after the metformin treatment. On the other hand, no significant correlation was observed between the change in PEDF levels and the clinical and laboratory findings. CONCLUSION: Our study is the first to identify a metformin-related increase in PEDF levels in diabetes. The increase observed in PEDF levels after the metformin treatment does not seem to be related to the changes in insulin resistance, fat mass or glycemic control. Hence, our results suggest that further investigation is necessary to determine the direct effects of metformin on PEDF gene and protein expression in vitro.

RESUMEN

Pulmonary alveolar microlithiasis (PAM) is a rare disease with alveolar microliths mainly composed of calcium phosphate. The gene responsible for the disease is SLC34A2, which encodes a type-IIb sodium phosphate cotransporter, has been described recently. Treatment of this disease is not clearly defined. Disodium etidronate is a member of bisphonates and it has been administered in these patients due to its inhibitory effect on the precipitation of hydroxyapatite microcrystals. Here, clinical and radiological improvement of two patients with PAM who were treated with disodium etidronate for 9 and 11 years, respectively, are presented. The pathogenetic mechanism of this treatment on the genetic basis of disease is discussed.

RESUMEN

PURPOSE: To evaluate computed tomography (CT) findings of pulmonary infections in immunocompromised patients with hematologic malignancies, and to detect the accuracy of first-choice diagnoses. MATERIALS AND METHODS: CT chest scans of 57 immunocompromised patients who had pulmonary infections were evaluated retrospectively, and a first and second interpretation of etiology (first- and second-choice diagnosis) was proposed. The etiology of pulmonary infection was verified by microbiological tests such as blood, sputum, bronchoalveolar lavage (BAL) cultures, sputum, and BAL smears, or diagnosed on the basis of response to treatment and clinical follow-up. RESULTS: Nineteen patients had a bacterial infection, 20 patients had a fungal infection, 8 patients had a cytomegalovirus (CMV) infection, 8 patients had Pneumocystis jiroveci pneumonia (PCP) and 2 patients had a Mycobacterium tuberculosis infection. There were consolidations in 13 patients (68.4%) and areas of ground-glass attenuation and ground-glass nodules in 6 patients (31.6%) with bacterial infection. Six of 8 eight patients (75%) with CMV infection had centrilobular nodules associated with bronchial wall thickening and ground-glass areas and nodules. There were parenchymal nodules in 18 of 20 patients (90%) who had a fungal infection. All 8 patients who had PCP had bilateral areas of ground-glass densities on CT scans. The first-choice diagnosis was accurate in most of the fungal infections (95.0%) and PCP (87.5%), but was less accurate for bacterial and viral infections (73.7% and 75.0%, respectively). Neither of the 2 tuberculous infections was identified on the basis of CT findings. CONCLUSION: In the evaluation of febrile immunocompromised patients, pulmonary fungal infection and PCP may be identified with high accuracy on the basis of CT findings.

RESUMEN

Denervation of sensory and sympathetic nerve fibers and reduced blood flow result in decreased bone mineral density (BMD). In this study, we aim to detect the effect of compression of brachial plexus and subclavian vessels on the forearm BMD in patients with thoraric outlet syndrome (TOS). Twenty-three patients with TOS (17 females and 6 males) were enrolled in the study. Thirty-three extremities of the patients with TOS were classified as true neurogenic (1), vascular (15) and disputed neurogenic TOS (17). Thirty upper extremities of 15 age- and sex-matched healthy subjects were evaluated as controls. Electrophysiological testings and Doppler ultrasonography were performed. Comparisons of the dominant and the non-dominant forearm BMD between patients and controls, and between the involved and the non-involved sides in TOS patients revealed no significant differences (P < 0.05). In conclusion, intermittent compression of brachial plexus and subclavian vessels in patients with disputed and vascular TOS does not seem to affect forearm BMD. Further studies are needed to detect the effect of persistent neurovascular compression in TOS.

RESUMEN

Pulmonary hypertension secondary to pulmonary venoocclusive disease (PVOD) is increasingly recognized (Wagenvoort, Chest 69:82-86, [20]; Scully et al., N Engl J Med 308:823-834, [21]). The clinical presentation is usually progressive pulmonary hypertension. It should be kept in mind when there is pulmonary arterial hypertension, pulmonary edema, and a normal pulmonary artery wedge pressure. Importance of diagnosing this condition is to protect patient from fatal pulmonary edema when using prostacyclins that are effective for treatment of primary pulmonary hypertension. Herein, we present multidetector computed tomography findings of PVOD in a pregnant woman that presented with pulmonary hypertension.

RESUMEN

We present a child with double aberrant left brachiocephalic vein (ALBCV) that was an incidental finding on CT. The anterior and thin branch was above the aortic arch and behind the truncus brachiocephalicus and drained into the superior vena cava (SVC). The posterior and thick branch of the ALBCV coursed posterior to the trachea and oesophagus and joined with the azygos vein before draining into the SVC. To our knowledge, retrotracheal ALBCV has not been previously described.

RESUMEN

Periportal region is an anatomic space around portal vein comprising hepatic artery, bile duct, nerves, lymphatics and a potential space. Periportal pathologies may involve any of these structures diffusely or focally with characteristic radiologic findings. Radiologic findings can be helpful in differential diagnosis of pathologies of periportal structures including periportal cavernomatous transformation, hepatic artery aneurysm, biliary diseases, neurofibromatosis, lymphoma, langerhans' cell histiocytosis, periportal fatty infiltration and other causes of periportal halo in adult and pediatric patients. Lobar/segmental intrahepatic involvement can be seen in neurofibromatosis, cavernomatous transformation, fatty infiltration and periportal edema. In this review, we discuss CT and MRI findings of periportal pathologies which can be in the form of diffuse or segmental/lobar involvement.

RESUMEN

PURPOSE: We surveyed the practices and policies of the radiology departments of academic institutions in Turkey regarding the use of low dose CT in daily practice. MATERIALS AND METHODS: Surveys were mailed electronically to radiology departments of 40 university hospitals. Information gathered included modifications of standard protocols for dose reduction according to body parts being examined or depending on specific patient groups such as children, pregnant, or slim patients. RESULTS: Thirty-three radiology departments (82%) responded. Twenty-eight (85%) reported that they modify CT scanning parameters in order to reduce the patient dose. Of these, 5 (18%) reported that they always modulate the scan parameters, 10 (36%) often, 11 (39%) sometimes, and 2 (7%) seldom. Reduced dose CT is applied mostly in pediatric and pregnant patients, reported by 93% and 57% of respondents, respectively. The most common body part for the application of low dose CT was chest examination followed by imaging of paranasal sinuses, abdomen, and CT-guided interventions. The most common modification for dose reduction is using low mA, followed by increasing the pitch value. CONCLUSION: Most respondents are aware of low dose CT, but the frequency of application varies considerably in routine practice. Reduced mA and increased pitch are the most commonly used modifications.

RESUMEN

We report a breast mass associated with a foreign body mimicking malignancy on mammography. Although retained penrose drains have been reported in other parts of the body, our case is the first report of a retained penrose drain in breast diagnosed by mammography. Mammography can be used if there is suspicion of a retained penrose drain during the course of breast abscess treatment.

RESUMEN

INTRODUCTION/OBJECTIVE: Our aim was to evaluate the positive predictive value (PPV) of the analysis of breast microcalcifications according to Breast Imaging Reporting and Data System (BI-RADS) and Le Gal's classification in identification of malignancy, and to assess the interobserver agreement using these criteria. METHODS AND MATERIAL: Eighty-two patients with breast microcalcifications on their screening mammograms underwent surgical excision after a needle localization at our institution between July 1993 and June 2000. The mammograms were examined by two experienced mammographers retrospectively and independently. Each observer noted the morphology, distribution, associated findings, final assessment categories of microcalcifications according to BI-RADS criteria and the morphologic type of microcalcifications according to Le Gal's classification. The PPVs for each radiologist and the interobserver agreement were determined by using these data and histologic findings. RESULTS: Histopathologic results yielded malignancy in 25 (30%) cases. The evaluation of microcalcifications according to BI-RADS criteria revealed PPVs of 17% and 25% for category 4 lesions, and 68% and 44% for category 5 lesions. In the assessment of microcalcifications according to Le Gal's classification, the PPV of type 4 lesions was 45% (for both observers), whereas the PPVs of type 5 lesions were 70% and 50%. The interobserver agreement was fair in evaluation of morphology of microcalcifications (kappa:0.31), distribution of microcalcifications (kappa:0.29), final assessment categories (kappa:0.27), and moderate in evaluation of associated findings (kappa:0.48) by using BI-RADS lexicon. It was higher for the assessment of milk of calcium and round microcalcifications than other typically benign microcalcifications, and for fine linear or fine linear branching microcalifications than other probably malignant calcifications. There was a fair interobserver agreement (kappa:0.30) in the description of the morphologic type of microcalcifications according to Le Gal's classification. DISCUSSIONS AND CONCLUSION: In our study, both BI-RADS lexicon and Le Gal's classification did not succeed expectedly in reducing the ambiguity in assessment of breast microcalcifications. Further studies and perhaps development of new methods are required to improve accuracy and standardization in mammographic interpretation.

RESUMEN

A one-week-old boy had undergone resection of a sacrococcygeal benign cystic teratoma. At the age of 12 months, he had a serum alpha-fetoprotein level of 139,000 IU/ml and a recurrent pelvic mass which was removed, and the microscopic examination revealed endodermal sinus tumor. Postoperatively, massively enlarged inguinal lymph nodes and abdominal distention developed. Computerized tomography displayed enlarged inguinal lymph nodes, metastatic lesions in the liver, and a pelvic recurrent mass. He received BEP (bleomycin, etoposide, cisplatin) chemotherapy regimen, and a complete remission was achieved with a normal serum alpha-fetoprotein. Close follow-up and serum alpha-fetoprotein monitoring are mandatory after the resection of a sacrococcygeal teratoma.

RESUMEN

STUDY DESIGN: A cross-sectional study was conducted. OBJECTIVE: To investigate the pediatric pedicle morphology with the help of modern computed tomography technology. SUMMARY OF BACKGROUND DATA: The use of pedicular screws recently has gained popularity because of their ability to provide three-dimensional correction of spinal deformity. Extensive work has been published on the pedicle morphology of the adult and adolescent thoracolumbar spine. Less is known about the pedicle morphology of children. METHODS: A total of 21 patients ages 5 to 10 years underwent standard spiral computed tomography of the abdomen. The patients were grouped according to age: Group 1 (5 to 8 years of age) and Group 2 (9 to 10 years of age). Images were reformatted, and multiplanar reconstructions were used to attain images of lumbar pedicles on sagittal, coronal, and transverse planes. The measurements included the inner and outer pedicle diameters on the transverse plane, the pedicle angle on both the transverse and sagittal planes, and pedicle length. RESULTS: The smallest pedicle lengths were 24 mm for Group 1 and 25 mm for Group 2. When the average values were considered, the smallest lengths were at L5 and the longest at L3. The smallest diameter was at L1 (2.3 mm for Group 1 and 3 mm for Group 2), whereas L5 had the largest diameter (6.17 mm for Group 1 and 8.72 mm for Group 2). In the transverse plane, the pedicle angle increased from L1 to L5 in both groups. In the sagittal plane, the angulations followed an opposite trend. CONCLUSIONS: The inner transverse diameter of the lumbar pedicle, particularly in young children, is smaller than previously reported. Insertion of screws currently available commercially screws seems to be safe in the L4-L5 pedicles of children ages 5 to 8 years, and in the L3-L5 pedicles of older children. Custom-made screws might be considered for upper levels for safe application.
