Administration of a tumour-seeking compound labeled with a low-energy isotope and intraoperative screening with the gamma probe (radioguided surgery, RGS) could be useful in reoperations for advanced neuroblastoma when the normal anatomy is altered. A pilot study was performed to test the feasibility of this technique. Five patients underwent six relaparotomies for recurrent stage III or IV neu...

Blue rubber bleb nevus syndrome (BRBNS) is a rare clinical entity characterized by multiple venous malformations (hemangiomas) of the skin and gastrointestinal tract. These hemangiomas usually cause episodes of occult gastrointestinal bleeding leading to iron deficiency anemia, and also carry a significant potential for serious hemorrhage. The 99mechnetium (99mTc)-labeled red blood cell scintig...

Insulinoma is a rare neuroendocrine tumour arising from beta cells of pancreatic islets Langerhans. We report case insulinoma presented with vague manifestations, which were undiagnosed for 2 years. The diagnostic evaluation revealed endogenous hyperinsulinism and imaging showed head lesion she underwent the surgery. Due to persisting symptoms, Calcium arterial stimulation hepatic venous sampli...

IMPORTANCE Sentinel lymph node biopsy has been proposed as an alternative to up-front elective neck dissection (END) for determination of pathologic nodal status in patients undergoing surgical treatment for oral cavity squamous cell carcinoma (OSCC) with clinically negative neck (cN0). Sentinel lymph node biopsy using current standard tracer agents and imaging adjuncts such as radiolabeled sul...

skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. the skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. the patients with skull meta...

PURPOSE To compare the volume of various spaces visible on optical coherence tomography (OCT) images in different angiographic lesion subtypes of neovascular age-related macular degeneration (AMD). METHODS Sixty-six cases of previously untreated, active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. CNV lesions were classified as occult with n...

INTRODUCTION In this study we retrospectively reviewed data on 311 consecutive elective cholecystectomies, performed for benign disease (cholelithiasis, cholecystitis) in our institution in the last six years, in order to determine the frequency of unexpected gallbladder pre-neoplastic and neoplastic lesions and analyse their clinical, diagnostic and therapeutic features. MATERIALS AND METHOD...

HYPOTHESIS Preoperative parathyroid and thyroid imaging using technetium Tc 99m sestamibi scintigraphy-single-photon emission computed tomography (Tc 99m MIBI SPECT) and technetium Tc 99m sodium pertechnetate, respectively, in patients with parathyroid adenomas and concomitant multinodular goiters enables the selection of those suitable for minimally invasive radio-guided surgery. DESIGN One ...
