Role of 68Ga-DOTATOC PET/CT in the Evaluation of Primary Pulmonary Carcinoids
( Tarun Jindal ),( Arvind Kumar ),( Balasubramanian Venkitaraman ),( Roman Dutta ),( Rakesh Kumar ) 대한내과학회 2010 The Korean Journal of Internal Medicine Vol.25 No.4
Background/Aims: Although carcinoid tumors usually have good prognosis, early and specific diagnosis is important. Computed tomography and magnetic resonance imaging do not provide findings that are specific for carcinoids, and somatostatin receptor scintigraphy suffers from low spatial resolution. 18-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has limited sensitivity for carcinoids due to low uptake of the marker. A PET/CT system that uses the somatostatin receptor-based PET tracer 1,4,7,10-tetraazacyclododecane-NI,NII,NIII,NIIII-tetraacetic acid (D)-Phe1-thy3-octreotide (68Ga-DOTATOC) has also been used in the evaluation of carcinoids, although information regarding its use for the detection of primary pulmonary carcinoids is limited. Thus, we investigated the value of 68Ga-DOTATOC PET/CT for the diagnosis of primary pulmonary carcinoid tumors. Methods: This was a retrospective analysis of patients with primary pulmonary tumors who underwent 68Ga- DOTATOC PET/CT. All the patients had a histopathologic diagnosis of carcinoid. The rate of detection of primary pulmonary carcinoid tumors using 68Ga-DOTATOC PET/CT was assessed. Results: Twenty patients were diagnosed as having carcinoid, and 19 tumors showed significant uptake on 68Ga- DOTATOC (detection rate, 95%). The maximal standardized uptake value (SUVmax) ranged from 1.1 to 66, with a median value of 21.6. In one patient, 68Ga-DOTATOC PET/CT revealed additional lesions. Conclusions: Our results demonstrate that 68Ga-DOTATOC PET/CT is useful in the evaluation of primary pulmonary carcinoids and should be included in the diagnostic work-up of these patients.

Management of an Iatrogenic Injury in a Crossed Ectopic Kidney Without Fusion
Tarun Jindal,Mir Reza Kamal,Satyadip Mukherjee,Soumendra Nath Mandal,Dilip Karmakar 대한비뇨의학회 2014 Investigative and Clinical Urology Vol.55 No.8
Crossed renal ectopia is a condition in which a kidney is located on the side oppositeof its ureteral insertion. Ninety percent of crossed ectopic kidneys are fused to theiripsilateral uncrossed renal unit. Crossed renal ectopia without fusion is rare, with only62 patients reported in the literature to date. These kidneys may suffer iatrogenic injuryduring an unrelated surgical intervention. The injury, unless self-limiting, may necessitatethe removal of the ectopic kidney. We present a unique case of a dual injury, renalas well as ureteric, in a crossed ectopic kidney without fusion that was successfully managedwithout surgical excision.
Case Report : Tuberculosis of the urachal cyst
( Tarun Jindal ),( Mir Reza Kamal ),( Jayesh Kumar Jha ) 대한내과학회 2013 The Korean Journal of Internal Medicine Vol.28 No.1
Urachal cysts are uncommon. Rarely, these cysts can become infected. Tuberculosis of the urachal cyst is exceedingly rare, with only one case reported previously in the English language literature. Here we report the case of a 23-year-old male who presented with an infra-umbilical mass that turned out to be tuberculosis of the urachal cyst.
Isolated Congenital Urethrocutaneous Fistula of the Anterior Urethra
Tarun Jindal,Mir Reza Kamal,Soumendra Nath Mandal,Dilip Karmakar 대한비뇨의학회 2011 Investigative and Clinical Urology Vol.52 No.5
Isolated congenital urethrocutaneous fistula of the anterior urethra is an extremely rare anomaly in which, along with a normal urethra and meatus, a fistula is present. These cases usually present in the pediatric age group. To date, only one such case has been described in the adult population. We describe one such case in an adult and discuss the management of this uncommon anomaly.

Over the last decades, there has been a significant stage migration in renal cell carcinoma and especially older patients are getting diagnosed more frequently with low stage disease, such as small renal masses ≤4 cm of size. Considering the particular risk profile of an older population, often presenting with a nonnegligible comorbidity profile and progressive renal dysfunction, treatment approaches beyond aggressive radical surgical procedures have come to the fore. We sought to give a contemporary overview of the available different treatment strategies for incidental small renal masses in an elderly population with the focus on comparative oncological outcomes of nonsurgical and surgical modalities.
