An unusual case of sarcoidosis presenting as calf pain.

Sarcoidosis is a multisystem chronic inflammatory disease predominantly affecting the lungs. Myositis as a presenting manifestation of sarcoidosis is extremely uncommon and seldom reported. Here we report a 20-year-old male who presented with bilateral calf pain for six months. On evaluation magnetic resonance imaging showed features of myositis, and muscle biopsy was suggestive of sarcoidosis with granulomatous vasculitis. Positron emission tomography-computed tomography scan revealed involvement of spleen in addition to the muscles. Patient was managed with corticosteroids and azathioprine, and showed good treatment response.

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. Not only as a diagnostic aid, it also helps in decision making for surgical correction by depicting the changes in drainage and GFR in different postures. We describe a case of Nephroptosis where DTPA Renal Scintigraphy addressed the diagnostic and therapeutic issues in the case.

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. Radionuclide single photon emission computed tomography (SPECT) scintigraphy is highly sensitive in localizing the active nidus and also orients the lesion in a three-dimensional plane well, for effective surgical removal.

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.
