we report a case of prostatic adenocarcinoma, initially presenting with generalized lymphadenopathy, and mimicking lymphoma on flurodeoxyglucose positron emission tomography/computed tomography (fdg pet/ct). our case suggests that in elderly men presenting with generalized lymphadenopathy, the diagnosis of metastatic prostatic carcinoma should not be overlooked even in the absence of typical ur...
Objective(s): 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET-CT) is a well-used and established technique for lung cancer staging. Radiation therapy requires accurate target volume delineation, which is difficult in most cases due to coexisting atelectasis. The present study was performed to compare the 18F-FDG PET-CT with contrast enhanced computed tomogr...
conclusions the automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. however, bolus tracking is associated with reduced variability for liver enhancement among different patients. results forty-eight patients (23 male, 25 female, mean age=56.4±13.5 years) were included. the contrast enhanceme...
Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...
perivascular epithelioid cell tumor (pecoma) is a rare mesenchymal tumor composed of immunohistochemically and histologically distinctive perivascular epithelioid cells. here, we report on the computed tomography (ct) and magnetic resonance imaging (mri) findings of ovarian pecoma with pulmonary metastasis. the tumor was visible as a multilocular hemorrhagic mass that encased the ovarian vessel...
This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...
Gastrointestinal duplication cysts are a rare congenital malformation in the gastrointestinal tract, most commonly seen ilium. The present study reported child with mid ileal cyst ofthe ectopic gastric mucosa that was diagnosed by Technetium-99m pertechnetate single-photon emission computed tomography-computed tomography (SPECT-CT) scintigraphy. can massive lower bleeding early childhood (Mecke...
An inflammatory pseudotumor (IPT) is a rare benign lesion, characterized by nonneoplastic proliferation of inflammatory cells and presence of intermingling collagen fibers. IPT commonly occurs in the lungs and orbita, while an intraspinal IPT is extremely rare. IPT can mimic both clinically and radiologically malignant processes, and making a definitive preoperative diagnosis is often difficult...
