Unusual Artifacts Encountered during Routine Studies on Positron Emission Tomography-Computed Tomography and Gamma Camera.

Artifacts in nuclear medicine imaging are not uncommon. We are aware of some of these, for which we follow necessary protocols to avoid them. However, there are some unusual and unavoidable artifacts that we come across in daily imaging, which may be of concern and need to be detected and corrected on time.

Long-term Outcome of Laparoscopic Surgery for Nonpalpable Undescended Testis.

Aims And Objectives: The aim of this study was to objectively assess the long-term results of laparoscopic orchidopexy in patients who were diagnosed clinically to have nonpalpable undescended testis (UDT).

Materials And Methods: All operated cases of nonpalpable UDT from January, 2000, to January, 2014, were reviewed. After informed consent, all patients were subjected to a color Doppler ultrasound examination to assess the location of the testis, its size, blood supply, and consistency.

A Simplified Risk Score to Estimate the Risk of Contrast-Induced Nephropathy after Contrast Exposure.

Introduction: Scores are available to predict the probability of contrast-induced nephropathy (CIN) after cardiac interventions, but not many scores are available for non-cardiac interventions and there are none for intravenous exposure to contrast. We designed this study to develop a simplified score to determine the probability of developing CIN in patients exposed to the parenteral contrast medium.

Methods: This was a prospective study of patients who received parenteral contrast.

F-FDG PET-CT Evaluation of Primary Adrenal Ewing Sarcoma with Venous Thrombosis: An Unusual Presentation.

Ewing sarcoma (EWS) is primarily an osseous malignancy of childhood and young adults. Extraskeletal occurrence is less frequent and primary adrenal involvement is an even rare presentation. We present such a case of a 7-year-old boy diagnosed with adrenal EWS with associated venous thrombosis and pulmonary embolism detected on F-fluorodeoxyglucose positron emission tomography-computed tomography scan.

Role of F-Fluorodeoxyglucose Positron Emission Tomography-Contrast-Enhanced Computed Tomography in Detection of Early Recurrence with Peritoneal Disease in a Case of Adrenocortical Carcinoma.

Pazopanib-Induced Asymptomatic Necrotizing Pancreatitis Diagnosed on F-FDG PET-CT Scan.

Multi-targeted tyrosine kinase inhibitor (TKI) pazopanib approved for the treatment of advanced soft tissue sarcoma (STS) has prolonged the estimated survival times and quality of life of patients. However, several adverse effects associated predominantly with the inhibition of the vascular endothelial growth factor receptor by these drugs may prove to be potentially life-threatening. One such rare adverse event with the use of pazopanib is acute pancreatitis.

Pituitary Apoplexy Following Severe Diabetic Ketoacidosis, with Two Uncommon Complications of Supraventricular Tachycardia and Acute Limb Ischemia, in a Patient with Neglected Pituitary Adenoma and Undiagnosed Diabetes Mellitus: A Rare Clinical Association.

Pituitary apoplexy (PA) is a clinical emergency arising from acute ischemia or hemorrhage of the pituitary gland. A small subset of pituitary adenomas present with an apoplectic crisis, with common symptoms being headache, nausea-vomiting, visual impairment, ophthalmoplegia, altered sensorium, and panhypopituitarism. Though diabetic ketoacidosis (DKA) is an established complication of uncontrolled diabetes mellitus, its association with PA is extremely rare.
