Mnemonics for the differential diagnosis of lucent/lytic bone lesions include: FEGNOMASHIC FOG MACHINES They are anagrams of each other and therefore include the same components. They are by no means exhaustive lists, but are a good start for


10 Feb 2013 This patient had metastatic lung cancer to the bones. Bone metastases are classified as either blastic or lytic: Lytic bone metastases occur in the following cancers: renal, lung, OPEN ACCESS RADIOLOGY EDUCATION .

Diagnosis no fracture or lytic lesion. Lytic lesions In children and young adults, the differential diagnosis of solitary lytic lesions includes eosinophilic granuloma, epidermoid-dermoid, os-teoblastoma, hemangioma, and aneurysmal bone cyst. In older patients with multiple lytic lesions, metastases and multiple myeloma should be considered. lytic lesion. (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.

Benign bone lesions such as osteophytes (n = 576), degenerative sclerosis (n = 367), The average runtime of the CADe system is 95±12 s per Schmorl’s nodules (n=146), osteoporotic areas (n=96), patient. Bone metastasis. 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.


Four MR patterns of vertebral metastatic disease are seen – focal lytic, focal sclerotic, diffuse inhomogenous, diffuse homogenous. The most common among them is focal lytic lesions characterized by low signal intensity on T1 and high on T2. Pedicle destruction is more in favour of metastatic etiology. MRI may detect lytic bone metastases in patients with negative radiographs, CT or bone scans. This is explained by the fact that over 30 % of bone loss must occur before a lesion becomes apparent on CT images and a much higher percentage of bone loss (about 50 %) is required for osteolysis to become evident on plain radiographs.

2015-03-05 · Bone metastases in breast cancer may be osteolytic, osteoblastic, or mixed blastic and lytic.

The poor sensitivity of radiographs, requiring up to 50% of bone to be destroyed before lytic metastases are visible,(31) and slow or absent changes following successful therapy, are well-recognized.(32) In the diffusion-weighted sequence, lytic metastases were hyperintense in all cases, with an apparent diffusion coefficient (ADC) value higher than normal bone but lower than lesions with acute edema of benign etiology.

Sensitivities and false-positive rates (FPRs) for training and testing sets were calculated for these lesions, which were probable lytic metastases with areas 0.8 cm 2 or greater.

Because bone marrow (including hematopoietic or "red" marrow) contains a high percentage of fat, T1‐weighted MRIs generally reveal metastases as focal areas of low signal intensity. MRI is the investigation of choice in the diagnosis and treatment evaluation of osteomyelitis following ra-diographs. The sensitivity and specificity of MRI are higher than those of any other imaging modality avail-able (8).
