This lytic metastasis in the right femur (arrow) has caused significant erosion of the cortex, and is therefore at risk of causing a pathological fracture. The lesion was identified initially on a staging whole body bone scan (right-hand image, arrow). This patient had breast cancer – while most metastases from breast cancer are … We studied only purely lytic metastases to avoid interference because of the presence of calcium in sclerotic and mixed metastases. Study inclusion criteria were (1) the presence of pure lytic bone metastases of the iliac bone and/or upper femurs as demonstrated on computed tomography (CT) and (2) the presence of pain or risk of fracture indicating the need to perform radiotherapy of the lesions. high sensitivity for detecting skeletal metastases, but targeted computed tomography (CT) or magnetic resonance imaging (MRI) may be needed to increase speciﬁ city.

(e) Follow-up CT at 3 months shows that the lesion has grown, confirming lytic metastases. MRI vs bone scintigraphy in renal cancer The British Journal of Radiology, August 2009 635. radiologist had at least 10 years’ experience in their respective areas. Plain radiographs have poor sensitivity to bony metastases, with detection dependent upon extensive cortical bone destruction. MR is the most sensitive imaging modality in clinical use today. In terms of lytic (those illustrated in the current case) and sclerotic lesions, prostate carcinoma can be of either type, or mixed, but is commonly Bone metastases can be classified as lytic, blastic, or mixed depending on the activity of tumor-stimulated host osteoclasts and osteoblasts. 12 Osteoclasts are large, multinucleated cells with a specialized cell membrane (the “ruffled border”) that resorb bone, and osteoblasts are smaller, mononucleated cells that form new bone.

Bone metastases from lung cancer are usually lytic. In one third of the cases, however, and in most patients with carcinoid tumours, the metastases are sclerotic (2). Some patients with bone metastases from lung cancer develop excentrically lytic lesions with one-sided destruction of cortical bone (22).

The large destructive lesion replacing the left pubic bone in this case (arrows) was a metastasis from lung cancer.

Lytic bone metastases such as from renal cell and thyroid carcinoma may not induce sufficient reparative bone formation for the lesion to be detected on bone scan. B, Sagittal reformation of a CT of the spine in bone windows demonstrates lytic metastases. CT is useful for assessment of the structural integrity of the axial skeleton. Skeletal metastases (a.k.a. bone metastases) are common and result in significant morbidity in patients with metastatic disease.Although the diagnosis is often straightforward, especially as in many cases there is a well-documented history of metastatic malignancy, sometimes they may mimic benign disease or other primary malignancies. Lytic vs blastic in the "lead kettle" PB-KTL mnemonic. By knowing the typical behavior of the metastatic lesion - lytic or blastic - you can help sort between the types to make the mnemonic even more useful.

• PET detects more lytic than blastic metastases, the opposite of bone scan.

The signal intensity of the metastatic deposits will vary according to the degree of mineralization. The majority of bone metastases are lytic (the only two exceptions that you need to know about are breast and prostate).
