It is well recognized that colorectal cancer does not frequently metastasize to bone. The aim of this retrospective study was to establish whether colorectal cancer ever bypasses other organs and metastasizes directly to bone and whether the presence of lung lesions is superior to liver as a better predictor of the likelihood and timing of bone metastasis.(More)
Imaging with Tc-99m labeled red blood cells (RBC) is increasingly being used in the detection of acute gastro-intestinal bleeding, especially in patients with intermittent bleeding. A patient is presented in whom the labeled RBC scan was helpful in the incidental discovery of a previously unsuspected probable angiosarcoma of the right femur and adjacent(More)
A neck mass in the right carotid triangle of a 28-year-old woman was found to be the only thyroid tissue she possessed. Resection of the mass led to clinical and biochemical hypothyroidism. A possible explanation for the unlikely occurrence of lateral aberrant thyroid tissue and absence of a thyroid gland in the usual location is offered. It is suggested(More)
PURPOSE The aim of this study was to evaluate the impact of DaTscan in a heterogeneous group of patients with movement disorders as well as the degree of confidence in scan findings between different readers. PROCEDURES A retrospective evaluation of consecutive patients who underwent DaTscan during 1 year was performed. The patients' demographics,(More)
AIM The aim of this study was to evaluate the role of single photon emission computed tomography and/or computed tomography (SPECT/CT) in differentiating metastatic from benign solitary skull lesions. MATERIALS AND METHODS Consecutive patients who had a SPECT/CT of the head subsequent to a whole-body bone scan (WBS) for the evaluation of a single skull(More)
A case of pericholecystic hyperperfusion on Tc-99m sulfur colloid (SC) flow images with a pericholecystic rim of increased activity (PCHA) on delayed planar and single-photon emission computed tomography images of the liver was seen in a patient with a history of multiple renal transplants admitted with cramping right lower quadrant abdominal pain.(More)
Tc-99m labeled RBC imaging is becoming increasingly useful in detecting gastrointestinal (GI) bleeding sites. A patient is presented who had massive GI bleeding from an unsuspected gastric leiomyoma in whom a Tc-99m sulfur colloid GI bleed image was negative. The Tc-99m labeled RBC imaging done on the day after sulfur colloid imaging revealed increased(More)
Inguinal herniation of the urinary bladder is not routinely seen in clinical practice. Most patients are asymptomatic and are diagnosed incidentally on diagnostic imaging or during the course of surgical repairs. Bladder herniation has previously been reported on ultrasonography and computed tomography, but not on positron emission tomography (PET) imaging.(More)
