Abstract
High-resolution real-time ultrasound (US) and computed tomography (CT) were compared in 48 patients with a clinical diagnosis of thyroid abnormality and also correlated with biopsy or surgery. The modalities were considered comparable in 38 cases (79%), while CT was superior in 5 and US in 5. CT illustrated substernal extension of a goiter, demonstrated a 5-mm nodule not seen in US, showed 2 cases of thyroiditis better than US, and diagnosed a suspected thyroid mass as a lipoma anterior to the thyroid. US detected 4 nodules not seen on CT and resolved contiguous nodules that appeared to be a single nodule on CT. Both techniques lacked histopathological specificity. CT appears to be advantageous in detecting substernal thyroid extension and confirming thyroiditis, while the ability of US to detect small nodules makes it the procedure of choice in evaluating suspected intrinsic thyroid abnormalities.

Abstract
The CT features of endobronchial granular cell myoblastoma are reported in an acknowledged heavy smoker without pulmonary complaints. Computed tomography confirmed the intraluminal location of the mass, demonstrated associated atelectasis, and detected the lack of adenopathy or invasion into the mediastinum, thus contributing significantly to surgical planning.

Abstract
High-density renal masses are atypical lesions that represent a diagnostic dilemma for computed tomography (CT). The differential diagnosis includes mainly complicated benign cysts and malignant neoplasms. This report analyzes the CT findings in 17 cases of discrete, sharply marginated masses that initially exceeded the density of the uninvolved renal parenchyma, averaging 50 H or more. The subsequently proven pathologic entities responsible for these high attenuation values included primary malignancies in six patients, one of whom also had multiple retention cysts containing highly proteinaceous, gelatinous material; a hemorrhagic cysts with an associated desmoplastic, fibrotic reaction in one patient; and single or multiple hemorrhagic cysts in four patients. No histologic proof was obtained in six patients, three with neoplastic disease and one mentally retarded youth who underwent renal aspiration without sufficient material obtained for analysis. Two patients with presumed hemorrhagic cysts have had serial CT scans without interval change in 8-12 months. An approach to the therapeutic management of affected patients is described.

Abstract
Yersinia enterocolitica is becoming increasingly recognized as a source of abscess formation in patients with numerous underlying disease entities, most notably hepatic and hematologic disorders. Patients ranging in age from infancy to adulthood can become infected with this worldwide pathogen, which seems to be relatively rare in the United States. We present the appearance of a Yersinia abscess on computed tomography in the hope that an increased awareness of this infection will result in earlier diagnosis and improved therapeutic management.

Abstract
Soft tissue calcification occurs in a variety of disorders. When it is associated with an abnormal calcium phosphorous product, it may present as large, periarticular masses that demonstrate layering on horizontal beam radiographs or computed tomography (CT). Previous reports have shown this phenomenon in idiopathic tumoral calcinosis. We report two patients with metastatic calcification of different etiologies: one patient with tumoral calcinosis and one with secondary hyperparathyroidism complicating chronic renal failure. Both showed layering on CT. The pathology of this phenomenon as well as therapeutic implications are discussed.

Abstract
The physical and psychological changes of pseudocyesis have bewildered physicians since the time of Hippocrates. We present the case of a 14-year-old girl as a reminder that pseudocyesis needs to be considered in adolescents and that the diagnosis may not be obvious, even with current technologies. We document that gaseous distension and abdominal fat deposits can lead to dramatic abdominal fullness and can mimic a term pregnancy.

Abstract
Thirty-six of 119 patients with myasthenia gravis examined by computed tomography for possible thymic mass had a thymectomy. The computed tomographic findings were compared to the findings of chest x-ray and linear tomography and then correlated with the surgical histopathologic results. Computed tomography detected all cases of thymoma or thymic enlargement due to hyperplasia. Chest x-ray correctly demonstrated 50% of thymomas present while linear tomography demonstrated 88%. Computed tomography was not able to distinguish between enlargement due to thymoma or hyperplasia unless calcification was present. The role of computed tomography is detailed and discussed in relationship to the other diagnostic modalities.

Abstract
Neurofibromatosis is a relatively common disorder that often involves many organ systems. One of the least understood aspects of this malady is a well documented potential for sarcomatous degeneration of neurofibromas. The inability to identify patients at risk and the lack of noninvasive screening methods for symptomatic patients often leads to late diagnosis. In six of seven subsequently proven neurofibrosarcomas, CT demonstrated low-density areas that histopathologically appeared to be due to necrosis, hemorrhage, and/or cystic degeneration. The density differences within these sarcomas were enhanced by the intravenous administration of iodinated contrast agents.

Abstract
A total of 144 gray-scale sonograms were obtained in 110 children to evaluate the pancreas. The entire gland was adequately visualized in just over 86% of cases. The size, contour, echo pattern, and echo intensity were assessed. Either diffuse or focal enlargement of the pancreas was the most consistent finding in the 25 children with pancreatitis. In contrast to previous reports, decreased echo intensity was not a reliable indicator of inflammation. Numerous complications were detected on the 54 sonograms of these 25 patients. These complications included pseudocysts, lesser sac fluid collections, ascites, biliary obstruction, and hemorrhage. It is recommended that ultrasound be the initial imaging procedure in the evaluation of children with suspected pancreatic disease, and that it be used in conjunction with clinical and biochemical data.

Abstract
Diagnostic pelvic lymphadenectomies are used in both bladder and prostate carcinoma. Enhanced rapid-sequence computed tomographic (CT) scanning of the retroperitoneum and pelvis was done prospectively in patients scheduled for lymphadenectomies. The CT results were then compared to the histopathological findings in 32 patients to analyze the ability of dynamic CT to indicate whether a lymphadenectomy is needed. The comparison showed eight true positive, four false negative, 18 true negative, and two false positive. The sensitivity was 66%, specificity 90% and accuracy 81%. The diagnostic considerations of the role of CT based on these findings are illustrated and discussed.

Abstract
Twenty-four cases of Wilms' tumor were analyzed. The gray-scale echographic characteristics of the tumors were categorized. Correlation with pathologic characteristics, clinical presentation, prognosis, and therapy response was assessed. Two echographic patterns emerged: (a) hypoechoic solid--3; and (b) hyperechoic solid--21. Necrotic degeneration as well as decrease in tumor size were echographic features correlated with positive response to therapy. The results of this analysis showed no initial correlation between the echographic patterns and the clinical presentation or prognosis. On the other hand, the echographic features of Wilms' tumor seem distinctive enough to help in etiologic differentiation and therapy management.

Abstract
To evaluate the ability of gray-scale renal ultrasonography to distinguish cystic neoplasms from benign cysts, 182 cysts or cyst-like masses were reviewed retrospectively by three radiologists with varying degrees of experience in nephrosonography. All cases were proved by needle puncture or surgery. An unequivocal diagnosis of "cyst" based solely on ultrasonography was 98% accurate, with 2% being due to hematomas, localized hydronephrosis, or septa within the cyst. No cystic neoplasms were mistaken for benign cysts. These results indicate that experienced observers using proper technique will rarely be in error in distinguishing non-neoplastic cystic masses from cystic neoplasms by articulated-arm gray-scale ultrasonography, and that routine needle puncture may be unnecessary in such cases.

Abstract
Ultrasound was evaluated in 69 patients for its usefulness in distinguishing scrotal abnormalities requiring surgery from those that may have clinical follow-up only. Distinction was possible in the majority of cases. On imaging, tumor showed decreased echogenicity within the testicle, which was usually enlarged. Epididymal enlargement, marked increase in peritesticular fluid, and skin thickening suggest a non tumorous condition. The ultrasound characteristics of various scrotal abnormalities are described.

Abstract
The therapy and prognosis of bronchioloalveolar carcinoma vary greatly with the solitary versus the diffuse form of the disease. Solitary disease demonstrates a high resectability rate with good long term prognosis. This contrasts with the rapidly fatal course associated with the diffuse form. To date, categorization of patients into either the solitary or the diffuse form has been based solely on conventional radiography. Multiple authors have reported cases of disease not demonstrated radiographically but discovered at surgery or autopsy. With the superiority of chest computed tomography (CT) for demonstrating parenchymal abnormalities, we propose that preoperative CT may be crucial in the workup of patients with presumed solitary bronchioloalveolar cell carcinoma. Early identification of diffuse disease or confirmation of the presence of solitary disease by CT may allow the institution of proper therapy and better evaluation of patient prognosis.

Abstract
To evaluate the impact of computed tomography (CT) on therapeutic management decisions in solid tumors of the chest and abdomen, 92 examinations on 54 children with 13 histologic tumor types were analyzed. The CT impact on the management decisions was analyzed in relation to other diagnostic procedures of the same body part including sonography, chest films with tomography, abdominal/pelvic films, and excretory urography. Overall, CT provided the essential information of 47% of management decision. By confirming non-CT examination results it helped direct therapeutic decisions in 28%. No additional information was derived from CT in 20%. Technically poor studies in 5% resulted in CT errors. According to the procedural method, CT provided additional information in 42% when compared with sonography, in 38% when compared with chest films and tomography, in 41% when compared with abdominal/pelvic films, and in 27% when compared with intravenous urography. The investigation showed that CT provided information directly affecting the therapeutic management decision in a significant number of patients.

Abstract
CT staging was performed in 49 consecutive patients with known carcinoma of the bladder. The overall accuracy of CT staging in 25 patients with surgically confirmed disease stage was 64%. Most diagnostic errors in this series were related to the determination of perivesical fat involvement by tumor. The overall accuracy of CT in predicting lymph node metastasis was 92%. The sensitivity was 60% and the specificity ws 100%. Because of the current management of bladder carcinoma, the major role of CT is in the evaluation of lymph nodes for metastatic disease. Since CT cannot detect metastasis to nonenlarged lymph nodes, it has only a limited role in the staging of bladder carcinoma at this time.

Abstract
CT scanning was performed on 29 consecutive patients with clinically localized prostatic carcinoma (stage A or B). Bipedal lymphangiography was performed in 12 cases. Histologic confirmation was obtained in 15 cases (pelvic lymphadenectomy in 12 and positive percutaneous needle biopsy in three). In these 15 proven cases, the overall accuracy of CT was 93% with one false positive and no false negatives. Lymphangiography was far less accurate (55%) with two false positives and three false negatives in 11 proven cases. The greater accuracy of CT resulted primarily from its ability to detect abnormal nodes in the pelvis, particularly hypogastric nodes, which are rarely opacified by lymphangiography. Preliminary experience suggests that CT is superior to lymphangiography in detecting early lymphatic spread from prostatic carcinoma in the pelvis. In the future, CT-guided percutaneous needle biopsy should be useful for documenting metastases in these patients.

Abstract
Thirty-six consecutive patients either with primary or recurrent carcinoma of the cervix were evaluated by computed tomography (CT) to assess CT's ability to screen patients prior to radical surgery. Overall accuracy when compared to surgical findings or skinny needle biopsies was 80%. In accuracies by CT were the results of inability to assess minimally enlarged lymph nodes, inability to distinguish fibrosis from recurrent tumors, and difficulty in delineating actual tumor invasion versus contiguity of adjacent pelvic organs. Computed tomography proved to be a sensitive indicator in delineating actual tumor bulk and sidewall extension. Information gained by CT compared favorably with that obtained by intravenous urography, barium enemas, lymphangiography, and nuclear medicine bone scans. This comparison indicates that CT can serve as a sensitive imaging modality to assess the surgical candidacy of patients either with initial or recurrent carcinoma of the cervix. An algorithm of studies is proposed based on this preliminary investigation.

Thirteen patients with a variety of renal pelvic filling defects were evaluated using computed tomography (CT). Nonopaque calculi and some blood clots can be more accurately differentiated with this modality than has heretofore been possible. In transitional-cell carcinoma of the renal pelvis, the main value of CT appears to be in tumor staging. CT may also be helpful where urography cannot discriminate between extrinsic compression and true intraluminal renal pelvic defects.

The sonographic appearances of 43 proved hypernephromas was characterized and correlated with the angiographic and pathologic features. This report details the findings and emphasizes the criteria for recognizing poorly echogenic tumors, which may be confused with cysts. A diagnostic dilemma may be posed by these tumors, particularly if angiography shows no evidence of tumor neovascularity. The end point in diagnostic work-up of these tumors must be based upon a correlative approach utilizing the clinical, urographic, sonographic, and angiographic data.

Abstract
Rarely do pancreatic pseudocysts extend into the mediastinum. We recently evaluated a case exemplifying this phenomenon. Although ultrasonography demonstrated the nature of the mass, computed tomography (CT) allowed better definition of various anatomic relationships and afforded improved definition of the superior aspect of the pancreatic pseudocyst. The role of CT and its advantages over ultrasonography in the diagnosis and management of pancreatic pseudocyst are discussed.

Abstract
Multiple fibrous lesions have been noted in the lower extremities of patients with neurofibromatosis (Recklinghausen's disease). These lesions are probably a combination of fibrous cortical defects, nonossifying fibromas, and intraosseous neurofibromas. When several fibrocystic lesions frequent the knee areas in an adolescent, neurofibromatosis should be suspected.

Diffuse hepatocellular processes are not well imaged by most radiologic modalities. At present, CT has not added significantly to the evaluation of hepatocellular disease, particularly in the cirrhotic liver. The CT patterns of cirrhosis previously described are reviewed, and the pathophysiology of cirrhosis is discussed. In 3 cases, a pattern was seen in cirrhotic livers characterized by nonuniform attenuation with varied response to administration of intravenous contrast agents. With further evaluation of fatty infiltration and cirrhosis, CT may prove helpful in understanding these disease processes.

Abstract
Thirteen patients with surgically proven endometriosis underwent ultrasonography as part of their diagnostic evaluation. An attempt was made to assess the sonographic characteristics of endometriosis to determine if a characteristic pattern would emerge when the clinical presentations and physical findings were coupled with the ultrasonic picture. Ultrasound showed pelvic masses in all patients. Most masses appeared spherical and separate from the uterus and were cystic or predominantly cystic with scattered peripheral echoes. This retrospective study suggests a more useful role for ultrasound than previously recognized in the clinical management of patients with endometriosis.
