Secondary tumoral calcinosis is a rare disorder that is most prevalent in patients with chronic renal failure. It is characterized by lobular densely calcified masses confined to the soft tissue, generally at the extensor surface of a joint in the anatomic distribution of a bursa. We describe a case of a 38-y-old man undergoing dialysis who presented with pyrexia of unknown origin and raised inflammatory markers but was otherwise asymptomatic. A (67)Ga scan was performed, on which an incidental diagnosis of secondary tumoral calcinosis was made. 相似文献

Periarticular tumoral calcinosis and hypercalcemia in a hemodialysis patient without hyperparathyroidism: a case report 总被引:1,自引:0,他引:1

We present a case of a 58-yr-old male to illustrate the scintigraphic, roentgenographic, clinical, and pathologic features of periarticular tumoral calcinosis that occurred in a hemodialysis patient. Soft-tissue calcifications developed 3 yr after onset of hemodialysis, became progressively larger during the ensuing five years, and culminated in voluntary withdrawal from dialysis because of the extreme discomfort and lack of mobility that resulted from the calcinosis. Histologically, an aplastic disorder was present with very low bone formation. On bone scintigraphy, intense calcium uptake in soft tissues implied that it was metabolically active. We hypothesize that this high metabolic activity contributed to the persistent hypercalcemia observed during the patient's last year of life. 相似文献

Tumoral calcinosis is a rare disorder manifest by large calcific periarticular masses. Associated bone destruction has been described previously only once. The radiographic and computed tomographic (CT) findings of bone erosion in a case of tumoral calcinosis in a renal dialysis patient are presented. Although the presence of bone destruction may suggest a neoplasm, it does not exclude the diagnosis of tumoral calcinosis. 相似文献

A case of tumoral calcinosis with tumoral deposits about the knee is reported. Radiographs demonstrate juxta-articular calcific deposits about the right second and fifth distal interphalangeal joints and the left first distal tuft, both hips, both shoulders, first distal phalanx of the left foot and right knee. Radionuclide images clearly demonstrate all areas of tumoral calcinosis. 相似文献

The authors describe a patient with follicular thyroid carcinoma who was receiving continuous ambulatory peritoneal dialysis to manage end-stage renal disease. To deliver radioiodine therapy to ablate thyroid remnants safely and under optimal conditions, the behavior of 37 MBq (1 mCi) I-131 was followed daily for 3 days. Blood activity and total body count decreased with a half-life of 100 hours (4.17 days). The daily iodide removal rate, estimated as a percentage of the total administrated activity, was low: 5.3% to 8.6% in peritoneal dialysate and 1.3% to 2.2% in urine. The thyroid uptake, measured using a probe, was 2.4% to 2.1% from day 1 to day 3 and 1.9% later at day 8. The volume of thyroid remnants was determined by ultrasonography to be 0.6 g. The patient received a reduced ablative I-131 dose of 814 MBq (22 mCi). Radiation emitted from the patient after I-131 therapy, monitored using a radiation monitor probe located at a distance of 1 meter, decreased with an effective half-life of 70 hours (2.9 days). The integration of the curve from t = 0 showed a level always less than 25 microSv/hour as early as 24 hours after treatment. Because the iodine removal rate is continuous but low in a case of peritoneal dialysis, smaller therapeutic doses must be administered to deliver maximal radiation to residual thyroid tissue while minimizing excessive radiation exposure to patients, their families, and medical staff. 相似文献

A 50-year-old man placed on peritoneal dialysis for end stage renal disease developed unilateral (left) scrotal edema following infusion of dialysis fluid into the peritoneum. The left side of the scrotum and left inguinal canal were surgically explored and a left hydrocele was removed. Following surgery, the patient again demonstrated left scrotal edema during peritoneal dialysis. Tc-99m MAA (5.0 mCi, 185 mBq) was injected into a 2-liter bag of dialysis fluid, which was subsequently infused into the peritoneum. The communication between the peritoneal cavity and the left inguinal canal was demonstrated. 相似文献

A 62-year-old patient with end-stage renal disease who is managed with continuous ambulatory peritoneal dialysis developed anterior abdominal wall swelling and pain that extended from just above peritoneal catheter site caudally. CT of the abdomen suggested pericatheter abscess with panniculitis. Tc-99m sulfur colloid peritoneal distribution planar scintigraphy suggested the diagnoses of pericatheter leak. The addition of SPECT/CT confirmed the latter diagnosis and pinpointed the exact location of the peritoneal leakage that was around insertion site. SPECT/CT was useful in establishing unequivocal diagnosis of peritoneal leak. 相似文献

A 62-year-old male with end-stage renal failure on peritoneal dialysis presented with sudden onset scrotal swelling following a violent coughing fit. He was referred for a peritoneal leak study to evaluate the scrotal swelling. This case illustrates the benefit of SPECT/CT imaging in the diagnosis and anatomic localization of peritoneal leakage as a complication of peritoneal dialysis. 相似文献

The aim of the study was to investigate the morphology of mesothelial cells of the peritoneum of patients with terminal renal failure (TRF), taken by the biopsy immediately before the onset of peritonal dialysis (PD), and to compare it with the findings in patients with PD. The samples were prepared in the way standard for light microscopy and transmission electron microscopy. In patients with TRF intracytoplasmatic inclusions could be observed, unusual protrusions of mesothelial apical surfaces, deformation of mesothelial cells and their detachment from the basal membrane, as well as the dilatated cisternae of granulated endoplasmatic reticulum with filamentous structures in some of them. In patients on PD cytoplasmic protrusions of different shapes and contents were observed at the surface of mesothelial cells, multiplication of basal membrane, occurrence of young forms of mesothelial cells as well as the detachment of those cells from the basal lamina. 相似文献

A 45-year-old man receiving continuous ambulatory peritoneal dialysis developed scrotal swelling and edema which was aggravated in the standing position. Physical examination failed to find inguinal hernia and although ultrasonography revealed the patent had processus vaginalias, it failed to prove its continuity to the peritesticular space of the tunica vaginalis. Peritoneal scintigraphy with intraperitoneal instillation of 99mTc-Macroaggregated albumin followed by standing clearly demonstrated the connection. The use of the standing load makes possible faster visualization of a positive finding and more accurate diagnosis than examination in the supine position. 相似文献

Continuous ambulatory peritoneal dialysis (CAPD) is utilized with increasing frequency for patients with end stage renal disease (ESRD). Several complications have been observed including catheter malfunction due to pericatheter leaks, abdominal wall and inguinal hernias and diaphragmatic leaks. Occasionally special diagnostic procedures are necessary to determine the nature of the abnormality and guide the surgical approach to correction. The four cases herein illustrate the usefulness of radionuclide imaging in diagnosing leakage of dialysate fluid in patients on CAPD. 相似文献
