Lymph nodes of the neck: evaluation with US.

Ultrasound (US) proved highly effective for detection, localization, and delineation of enlarged lymph nodes of the neck. Infiltration of adjacent structures, specifically the common, internal, and external carotid arteries, and the neck muscles was reliably demonstrated. Benign and malignant lymph node enlargement could not be differentiated. US examinations changed the operative course of 56% of patients studied. In 41%, a more radical operative procedure was performed than was previously planned; in 14%, US demonstrated inoperability. Small-parts US is a very useful adjunct to current imaging techniques of cervical lymph node disease.

[Sonographic localization of a bullet in the pericardium].

We report a case of pericardial localisation of a bullet by sonography. The metallic foreign body could be demonstrated by its typical sonographic appearance of a strongly echogenic lesion with acoustic reverberation artefacts. Sonography proved superior to the other diagnostic modalities including computed tomography.

[Malformation of the inner ear. Cerebrospinal otorrhea in stapedectomy].

Otoliquorrhoea occurred during stapedectomy (gusher) and signified a case of inner ear malformation which was not apparent on preoperative tomograms but could be demonstrated on postoperative CT scans. There was no bony separation between the irregularly dilated inner auditory canal and the vestibulum. The cochlea was not fully rotated. Intraoperative problems in such malformations may lead to further postoperative hearing impairment. Hence, we report on the clinical, operative and CT findings in order to avoid an operation in patients with similar signs and symptoms.

[Tuberculosis of the female breast: diagnostic clarification].

Modern therapeutic possibilities made tuberculosis of the breast a rare entity which, however, still exists and usually mimicks a malignancy. It represents a secondary organ manifestation and should be considered in differential diagnosis in all cases of primary lung tuberculosis and when fine needle biopsy fails to yield the expected tumour cells. We demonstrate such a case of breast tuberculosis and stress the cytologist's option to restain any cytological slide according to Ziehl-Neelsen. In our case, this renewed staining established the correct diagnosis.

The disease-free wall in coronary atherosclerosis: its relation to degree of obstruction.

Coronary atherosclerotic lesions are more often located eccentrically (70%) than concentrically (30%). In this study, the configuration of eccentric coronary artery atherosclerotic lesions was assessed by means of computerized planimetry in 100 specimens of eccentric arterial lesions. Special attention was given to the relation between the disease-free wall and the severity of obstruction. The mean disease-free wall are length measured between 17 and 23% of the total vessel circumference in eccentric coronary artery lesions that obstructed 50 to 90% of the cross-sectional area. This ratio persisted irrespective of the location of the lesion within the vessel and was not significantly different with vessels of different sizes. The presence of disease-free arcs of coronary artery wall as observed in this pathologic study may relate to three factors in clinical coronary artery disease: The published observations of spasm in segments of arteries harboring structural obstructive lesions may be explained by the frequent presence of uninvolved arcs of coronary artery walls. Multiple views during coronary arteriography are necessary to accurately reflect the degree of obstruction. The results of percutaneous transluminal coronary angioplasty may be influenced by both the disease-free arc and the atheromatous obstruction.

[Bedside chest x-rays and extravascular lung water determination in intensive care patients].

Radiological staging of pulmonary oedema was compared with the determination of extra-vascular lung water by means of a double indicator dilution technique. One hundred and forty-six ward chest radiographs were evaluated and compared with the results of simultaneous measurements of lung water. Seventy-seven cases could be evaluated statistically. Chest x-rays regarded as normal corresponded to extra-vascular lung water of 5 to 9 ml./kg. body weight. Interstitial oedema (radiological stage I and II) corresponded to extravascular lung water levels of 8 to 12 ml./kg. Differentiation of stages I and II was not possible. During stage III, extra-vascular lung water was 15 to 21 ml./kg. A comparative analyses of these findings revealed a discrepancy of 34%. The reasons for this are discussed.

Significance of balloon pressure recording during angioplasty. An experimental study.

During angioplasty of artificial stenoses, atherosclerotic human cadaver arteries, and normal canine arteries, pressure and volume of the dilatation balloons were continuously recorded. We found that a sudden yield of a lesion corresponded to a sudden drop in the pressure curve and an increase of the balloon volume. Volume monitoring was insensitive, but pressure recording was very precise. Continuous pressure recording, using a non-compliant inflation system, correctly demonstrated small breaks and ruptures of atherosclerotic vessels, changes not seen on fluoroscopy.

The relation between arterial and balloon rupture in experimental angioplasty.

Canine carotid, iliac, and femoral arteries underwent transluminal angioplasty with increasing balloon pressure from 4.5 to 12.5 atm. Balloons were selected according to vessel diameter: equal to (zero), 50% larger, and 100% larger than the vessel. The aim of this study was to assess possible disruption of the artery by a bursting balloon. With zero or 50% overdilation, arterial rupture did not occur despite balloon rupture. With 100% overdilation, arterial rupture always preceded balloon rupture. Rupture of all layers of the vessel was caused by severe overdistension, followed by secondary rupture of the balloon because it had lost its external support.

[Nonvisualization of the gallbladder lumen by sonography].

Out of 12 000 sonographic examinations of the abdomen in 211 cases the gallbladder was not visualized. The retrospective analysis of 41 patients revealed in 75% gallstones, in 15% space occupying lesions (4 carcinomas, 1 abscess, 1 sludge). In 10% the sonography gave a false positive result. The reasons are discussed.

[Radionuclide studies in chronically hemodialyzed patients. Bone scintigraphy for the evaluation and control of renal osteopathy].

The clinical applicability of bone scintigraphy (Tc99m MDP) was evaluated in 42 patients on maintenance hemodialysis. Typical scintigraphic findings are shown which were related to hormonal and biochemical parameters of calcium and phosphate metabolism. Visual grading of representative regions for metabolic bone disease in bone scans was compared to scintimetry which applies a bone to soft tissue ratio to grade osseous abnormalities. It could be shown that visual interpretation and grading of the findings according to a score is sufficient to assess the degree and extent of renal bone disease. Semiquantitative analysis of bone scintigrams by scintimetry did not improve the diagnostic information.

Obliteration of the gallbladder without formal cholecystectomy. A feasibility study.

Obliteration of the gallbladder without formal cholecystectomy was attempted in 36 rabbits, using an open technique for cannulation of the gallbladder during laparotomy. The gallbladder was cannulated, the proximal cystic duct was occluded with cyanoacrylate-nitrocellulose 2% wt/wt, and the gallbladder mucosa was exposed to various sclerosing agents to induce fibrosis. Heated 60% diatrizoate meglumine and absolute alcohol induced a controllable chronic cholecystitis with transmural fibrosis within two weeks, a result not seen with morrhuate sodium or in the control groups. All animals survived without complications, and no instances of common bile duct damage or occlusion was noted. The results reported are promising and indicate the need for further studies of this technique for its efficacy and safety.

Sonography of abdominal posttransplant lymphoma.

Five patients developed abdominal lymphoma an average of 89 months after successful renal transplantation. Sonographically, the lymphomas presented as bulky intraperitoneal masses or focal deposits in the liver. These lesions exhibited good sound transmission and intrinsic patterns ranging from sparse, soft echoes to coarse trabeculations. Prompt diagnosis of this serious late complication of renal transplantation is crucial.

Infantile peliosis hepatis. A case report.

Peliosis in a 13-month-old infant is described. This patient appears to be the youngest reported case. The radiologic diagnosis of peliosis is difficult. The condition may be confused with other more common liver diseases. Peliosis is best assessed angiographically.

Radiologic diagnosis of wandering spleen complicated by splenic volvulus and infarction.

Wandering spleen is a rare condition caused by malattachment of the dorsal mesogastrium. This condition is prone to torsion of the splenic pedicle leading to splenomegaly, hypersplenism, and infarction. Preoperative diagnosis can be suggested radiologically. A case of wandering spleen is reported and its embryologic, clinical, and radiographic features are discussed.
