Three-dimensional CT of congenital esophageal atresia and distal tracheoesophageal fistula in neonates: preliminary results.

OBJECTIVE: Radiography was traditionally used in the preoperative treatment of neonates with tracheoesophageal atresia and tracheoesophageal fistula. The aim of this study was to assess the potential use of three-dimensional CT in the evaluation of this complex congenital malformation. CONCLUSION: Three-dimensional CT coupled with reformations in the three orthogonal planes may have a complementary diagnostic role in congenital esophageal atresia.

Multimodality demonstration of primary splenic angiosarcoma.

Angiosarcomas are rare, accounting for only 1-2% of all soft tissue sarcomas. Primary abdominal angiosarcomas usually arise in the liver or spleen. We report the first color Doppler findings of a rare, low-grade splenic angiosarcoma in a 52-year-old woman.

Sonographic findings in ectopic cervical thymus in an infant.

We present the case of a 28-day-old boy with ectopic thymic tissue in the neck. Sonography showed a well-delineated, homogeneous lesion in the left submandibular region that was isoechoic relative to the mediastinal thymus. The lesion had angular margins and lacked a mass effect despite its large size (3 x 2 cm). On power Doppler imaging, arteries with an intermediate-impedance flow pattern were seen entering the lesion from the inferior and lateral margins. On both T1- and T2-weighted MR images, the lesion was isointense relative to the mediastinal thymus and had higher and lower signal intensity than muscle and fat, respectively. A sonographically guided needle biopsy confirmed the diagnosis of ectopic thymus.

Psoas abscess secondary to tuberculous lymphadenopathy: case report.

Tuberculous psoas abscesses, a well-known sequel of tuberculous spondylitis, very rarely develop without concomitant spinal involvement. We report a unique case where a psoas abscess was secondary to retroperitoneal tuberculous lymphadenopathy in a 13-year-old boy who had no demonstrable findings of spinal tuberculosis. Computed tomography showed an obvious communication between the necrotic and calcified retroperitoneal lymph node and the psoas abscess. To the best of our knowledge, fistulization of tuberculous lymph nodes into the psoas sheath has not been reported in the English-language literature.

Focal intrahepatic extramedullary hematopoiesis: color Doppler US and CT findings.

Focal intrahepatic extramedullary hematopoiesis is an extremely unusual condition that can mimic any other solid mass of the liver. Only seven cases have been reported in the literature. Color Doppler ultrasonographic findings of this rare entity have not been described. We report a case of focal mass in a myeloid metaplastic patient diagnosed as focal extramedullary hematopoiesis. Color Doppler findings of this rare condition are described and compared with computed tomography features.

Cross-sectional imaging in ureter tumors: findings and staging accuracy of various modalities.

We present cross-sectional imaging findings in eight patients with ureter tumors. Eight patients were examined by computed tomography (CT), seven by ultrasonography (US), and five by magnetic resonance imaging (MRI). All the lesions were detected by the three modalities. All modalities were accurate in excluding the periureteral invasion and lymphadenopathy in Stages 1 and 2 tumors. While CT and MRI identified the periureteral invasion and lymphadenopathy in four patients with advanced tumors, US failed to show the local invasion in three of four patients. Nevertheless, enlarged retroperitoneal lymph nodes could be detected sonographically in the three Stage 4 tumors. CT and MRI appear to have a high diagnostic sensitivity and staging accuracy in ureter tumors. Although US detects ureter tumors efficiently, this technique seems to be unreliable in showing local invasion in a substantial number of patients.

Radiographic, CT, and MRI findings in primary pulmonary angiosarcoma.

We report a rare instance of primary pulmonary angiosarcoma presenting as a large solitary mass in the left upper lobe with mediastinal invasion. In particular, we emphasize the magnetic resonance (MR) imaging features, which included a markedly heterogeneous pattern consisting of hyperintense areas scattered throughout a background of intermediate signal intensity, rendering the lesion a cauliflower-like appearance especially on T2-weighted images. Being unreported so far in primary pulmonary angiosarcomas, these distinct MR imaging findings may be helpful in the differentiation of these neoplasms from lung cancers.

Gadolinium-enhanced three-dimensional MR angiography in jugular phlebectasia and aneurysm.

True jugular vein aneurysms and phlebectasias are very rare abnormalities, which are usually discovered in children. Though their ultrasonographic features have been well described, magnetic resonance angiographic appearance of these lesions has not been reported in the radiology literature. We describe gadolinium-enhanced MR angiographic findings in two patients with internal jugular vein phlebectasia and one patient with anterior jugular vein aneurysm. The jugular venous system and its abnormalities were successfully depicted in the coronal plane, much like the images of coronal angiography.

Aneurysms of the portal venous system. Gray-scale and color Doppler ultrasonographic findings with CT and MRI correlation.

Two cases of incidentally detected aneurysms involving the portal venous system are described with emphasis on gray-scale and color Doppler ultrasonographic (US) findings. Appearing on US as anechoic masses showing direct luminal continuity with the right portal vein and superior mesenteric vein, the lesions displayed spectral findings characteristic of portal venous system on color Doppler US. Dynamic helical computed tomography (CT) demonstrated simultaneous enhancement with the portal system, while the aneurysms were hypointense owing to flow void on T1-weighted spin-echo magnetic resonance (MR) images.

Pulmonary tuberculosis with multifocal skeletal involvement.

Skeletal tuberculosis accounts for 1-5% of all tuberculosis infections. Of these infections, 50% involve the vertebral column and only 0-5% involve ribs. Rib tuberculosis is seen in only 0.1% of all tuberculosis infections. Skeletal tuberculosis is localised to a single site in 90-95% of reported cases. Multifocal involvement is uncommon and is usually associated with disseminated disease. We present a case of pulmonary tuberculosis associated with multifocal skeletal involvement.
