Nuclide Notes

🖼️ Osteoid osteoma of the cervical spine — reimagined in color, tension, and anatomy.

☢️ Disseminated TB ☢️ Masquerading as metastatic disease. FDG PET/CT shows hypermetabolic elongated polypoidal upper abdominal hypodense mass (biopsy proved of pancreatic origin) with regional and abdominal lymphadenopathy, disseminated multifocal osteolytic lesions involving the axial and appendicular skeleton, several showing cortical destruction and associated soft tissue components. The lumbar spine lesions are more aggressive, with paravertebral/extraosseous soft tissue extension extending through the ipsilateral neural foramina with linear soft tissue tracking along the course of the lumbar nerve root, in keeping with perineural spread.
🗓 Disseminated tuberculosis may rarely involve the pancreas and may present as a mass forming lesion, a focal hypodense pancreatic mass, or inflammatory soft tissue fullness around the pancreatic head/body. Involvement usually occurs as part of disseminated or miliary disease rather than isolated infection, and it represents only a small fraction cases, reported around 0.2–2% in recent reviews. Pancreatic head is most commonly involved, followed by the body abdominal tail.
