Interesting Skeletal Radiologic and Scintigraphic Outcomes and Their Logical Clinical Conclusions.

Skeletal scintigraphy with Tc-methylene diphosphonate and 18-fluorine-fluoride the main stay in cancer follow-up for early detection of skeletal metastasis often reveal confusing and conflicting findings requiring proper interpretation in conjunction with clinical-radiological correlation. A series of commonly encountered findings are presented for elucidation.

Great cervical venous tumoral thrombosis of melanotic medullary carcinoma thyroid: Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography enabled diagnosis and radiotherapy planning.

The authors report an extremely rare occurrence of a massive tumor thrombus involving right internal and external jugular veins extending into superior vena cava from a still rarer melanotic medullary carcinoma thyroid in the postoperative follow-up. The case was managed by hypofractionated intensity modulated radiotherapy technique with gratifying results.

Non heamoptytic massive Rasmussen's pulmonary artery aneurysm caused by aggressive cavitating squamous cell carcinoma metastasis.

The authors report an extremely rare occurrence of a massive aneurysm of a major pulmonary artery branch vessel caused by adjacent necrotizing aggressive squamous cell carcinoma metastatic mediastinal nodes. Despite the huge size, there was no hemoptysis due to the walling off effect by the necrotic nodes.

F18 FDG positron emission tomography revelation of primary testicular lymphoma with concurrent multiple extra nodal involvement.

Primary testicular lymphoma (PTL) a relatively rare disease of non-Hodgkin's lymphomas occurring with a lesser incidence of 1-2% has a propensity to occur at later ages above 50 years. PTL spreads to extra nodal sites due to deficiency of extra cellular adhesion molecules. We present detection of multiple sites of extra nodal involvement of PTL by F-18 positron emission tomography/computed tomography study aiding early detection of the dissemination thus aiding in staging and management.

Renal scintigraphy in diagnosis and management of nephroptosis.

Clinical manifestations of Nephroptosis are ubiquitous. Diagnosis is achieved after ruling out all other causes of abdominal pain by investigations. However, Nuclear Scan with Tc-99m GHA, MAG 3 and DTPA renal agents with dedicated imaging in supine and erect postures confirms the diagnosis5.

Scintigraphic and radiological correlative and confirmative features obviating invasive biopsy in Caffey's disease.

Caffey's disease is not a common clinical occurrence; it often poses problems in diagnosis due to its close resemblance to osteomyelitis. Initial plain radiographic diagnosis is sometimes fraught with the limitation of not being able to differentiate it from chronic osteomyelitis. Skeletal scintigraphy is sensitive in localizing the disease activity to the radiological features of the affected regions and the characteristic location of the lesions helps make the diagnosis without resorting to biopsy and further workup.

Nidus localization in osteod osteoma by SPECT skeletal scintigraphy: Aid to diagnosis and surgical approach.

Osteod osteoma, although not a common clinical occurrence, does pose problems both in diagnosis and surgical management. Initial plain radiographic diagnosis is sometimes fraught with the limitation of not being able to differentiate from chronic osteomyelitis and stress fracture. CT-aided localization of the nidus is also often inconclusive.
