F-18 Fluorodeoxyglucose Positron Emission Tomography Computed Tomography Findings in an Interesting Case of Primary Cauda Equina Lymphoma with Literature Review.

Primary lymphomatous involvement of spinal cord, nerve roots, and cauda equina is a rare entity and comprises only 0.1% of extra-nodal lymphoma spectrum. Here, we present a case of non-Hodgkin lymphoma involving cauda equina, initially suspected as ependymoma on magnetic resonance imaging that was later confirmed on nerve root biopsy as high B cell non-Hodgkin's lymphoma of L1-S1 nerve roots.

F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in the Evaluation of Intradiploic Epidermoid Cyst.

Epidermoid cysts are benign rare congenital cysts which typically present between 3 and 5 decade of life. They mostly arise from cerebellopontine angle or parasellar region, but sporadic cases arise from cranial dipole. Here, we present a case of 42-year-old female with painful soft swelling in the left frontal region, which on F-18 fluorodeoxyglucose (FDG) positron emission tomography-computed tomography is well-circumscribed non-FDG avid lesion.

Unusual Metastases in Papillary Microcarcinoma of Thyroid.

Papillary carcinoma thyroid is the most common type of thyroid cancer. Papillary thyroid cancer metastasizes commonly to regional lymph nodes, distant organ involvement is to lungs and bone are rare and is associated with poor prognosis. Metastases to intra-abdominal organs are extremely rare.

A Prospective Study Comparing Functional Imaging (F-FDG PET) Versus Anatomical Imaging (Contrast Enhanced CT) in Dosimetric Planning for Non-small Cell Lung Cancer.

Objectives: F-fluorodeoxyglucose positron emission tomography/computed tomography (F-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 F-FDG PET-CT with contrast enhanced computed tomography (CECT) in target volume delineation and investigate their impacts on radiotherapy planning.

Utility of 18 F-FDG PET/CT scan to diagnose the etiology of fever of unknown origin in patients on dialysis.

Introduction: Studies on fever of unknown origin (FUO) in patients of chronic kidney disease and end stage renal disease patients on dialysis were not many. In this study, we used 18 F-FDG PET/CT scan whole body survey for detection of hidden infection, in patients on dialysis, labelled as FUO.

Methods: In this retrospective study, 20 patients of end stage renal disease on dialysis were investigated for the cause of FUO using 18F-FDG PET/CT scan.

A clinical study of bilateral non-obstructive acute pyelonephritis with acute kidney injury in patients of type 2 diabetes mellitus.

The aim of our study was to study the clinical profile of type 2 diabetes mellitus patients admitted with the diagnosis of acute kidney injury (AKI) due to bilateral acute non-obstructive pyelonephritis. The bilateral involvement was identified on various imaging modalities (ultrasound, computed tomography, nuclear scintigrapy). All the patients had AKI.

Utility of bone scintigraphy in diagnosis of post- traumatic osteitis pubis.

Minor musculoskeletal injuries usually heal within few weeks with conservative treatment, but in pelvic injuries, symptoms may persist for long duration and patient need medical attention to get relief from disturbing pain symptoms. We present a case of post-trauma osteitis pubis in a 58-year-old female, who reported with lower abdominal and left side hip joint pain since 2 months, after an episode of trivial trauma to her pelvis. Technetium-99m methylene diphosphonate bone scintigraphy was performed, which confirmed the site of injury in symphysis pubis and left hip joint, by increased radiotracer localization at both of these symptomatic sites.

Role of lymphoscintigraphy in diagnosis and management of patients with leg swelling of unclear etiology.

Background: To study the utility of lymphoscintigraphy in detection of lymphatic obstruction in patients with leg swelling of unclear etiology, selection of site for nodo venous shunt procedure, and follow-up lymphoscintigraphic documentation of improved lymph flow in surgically treated limb.

Materials And Methods: Twenty four consecutive patients with leg swelling, 10 male, 14 female with mean age 47 years, range from 13 years to 74 years underwent lymphoscintigraphy. All patients were referred from Department of Plastic Surgery, after initial work-up, and routine investigations to rule out the other causes of leg swelling.
