Ocular melanoma (OM) is a rare noncutaneous malignancy and consists of 2 different subtypes based on the anatomic location in eye: uveal conjunctival melanoma. Like cutaneous melanoma, OM benefits from nuclear medicine molecular imaging nodal staging clinical management. Through illustration distinctive cases, we aim to demonstrate complementary roles standard lymphoscintigraphy, advanced SPECT...

Purpose: To evaluate the accuracy of computed tomography (CT) scan imaging in distinguishing lymphedema from deep venous thrombosis (DVT) and lipodystrophy (lipedema) in patients with swollen legs. Material and Methods: CT scans of the lower limbs were performed in 55 patients with 76 swollen legs (44Iymphedemas, 12 DVT and 20 lipedemas). Thirty-four normal contralateral legs were also similarl...

Lymphoscintigraphy is a nuclear medicine procedure that is used to detect sentinel lymph nodes (SLNs). This project sought to investigate fusion of planar scintigrams with CT topograms as a means of improving the anatomic reference for the SLN localization. Heretofore, the most common lymphoscintigraphy localization method has been backlighting with a (57)Co sheet source. Currently, the most pr...

We describe a case of filariasis presenting with severe chyluria and nephrotic-range proteinuria. There were no obvious findings of glomerulonephritis in the renal biopsy. Technetium-99m-human serum albumin (Tc-99m-HSA) lymphoscintigraphy revealed the presence of communications between lymphatic channels and the urinary tract. Ezetimibe (10 mg/day) was administered during hospitalization. Chylu...

BACKGROUND Lymphatic drainage from skin on the head and neck is complex. We sought to provide improved visualization and analysis of the patterns of head and neck skin lymphatic drainage using aggregated lymphoscintigraphy data. METHODS Lymphoscintigraphy data from 929 patients with cutaneous melanoma on the head and neck collected at the Sydney Melanoma Unit have been mapped onto a 3-dimensi...

PURPOSE Preservation of the anal sphincter in surgery for cancer of the distal rectum in an attempt to avoid colostomy has been a main concern of colorectal surgeons. Various proposed procedures contradict oncological principles, especially with respect to pelvic lymphadenectomy. Therefore, prior knowledge of pelvic lymph node involvement is an important factor in choosing the operative techniq...

Lymphoscintigraphy for sentinel node (SN) localization was performed on a 60-y-old man with a melanoma on his back. Skin contamination occurred as a result of the radiopharmaceutical dose administration. Skin contamination could result in a misinterpretation of the SN location. Careful observation of the procedure avoided a misinterpretation with this study.

b a ckground: the management of internal mammary (im) nodes in breast cancer lacks a well-defined consensus. lymphoscintigraphy identifies up to one-third of breast cancer patients with extra-axillary drainage, which is mainly located in the im chain. our aim in this meta-analysis is to identify the lymphoscintigraphy technique variables that effect im node identification. m ethods: an internet...

Background In recent years, magnetic resonance imaging lymphangiography (MRL) has emerged as a way to predict if patients are candidates for lymphedema surgery, particularly lymphovenous anastomosis (LVA). Our goal was conduct systematic review of the literature on use MRL preoperative planning in surgery. We hypothesized that could add valuable information standard evaluation patients. Methods...
