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.

Osteolytic metastases are the most common, representing about 75% of all metastatic lesions. The primary source is usually a carcinoma of the kidney, lung, breast, gastrointestinal tract, and thyroid .

It is important to remember, however, that some benign processes such as osteomyelitis, can mimic malignant tumours, and some malignant lesions, such as metastases or myeloma, can look benign. Factors aiding in the diagnosis of bone tumours and benign lytic lesions: MRI will clearly demonstrate all forms of spinal metastases – vertebral, leptomeningeal and cord lesions. The vertebral lesions will be visible on non-contrast MRI however most leptomeningeal metastatic disease and some cord metastases will only be apparent on a post-contrast MRI. See an example of leptomeningeal metastatic disease here. Se hela listan på oatext.com Prostate cancer is most often blastic, lung cancer is most often lytic, and breast cancer may be blastic or lytic.
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. Results: Training set sensitivity was 0.83 (10 of 12; 95% confidence interval: 0.51, 0.97), with an FPR of 7.4 per patient.
In. Metastatic Disease to Bone Osteoblastic, Osteolytic. Metastases are most common malignant bone tumors; Most involve axial skeleton. Skull, spine and pelvis most common sites of bony metastatic lesions include spine > proximal femur > humerus should not treat a bone lesion without tissue diagnosis of the lesion. Radiologic work-up revealed multiple lytic vertebral metastases on CT with Metastatic melanoma: correlation of MRI characteristics and histopathology. However, the appearance of widespread bony sclerosis cannot, in isolation, conclusively lead to a diagnosis of skeletal metastasis. Here we present two cases 28 Jun 2010 RECIST 1.1 specifies contrast administration for both MRI and CT scans. 5) or partial (rather than complete) sclerotic fill-in of lytic metastases Metastases · Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > The diagnosis is often straightforward, especially as in many cases there is a Lytic metastases; Sclerotic metastases; Mixed lytic and sclerotic metastases.
Imaging 2013;38:1310–1324. VC 2013 Wiley Periodicals, Inc. SCLEROTIC (T2 dark) lesions of the spine are infre-quent and, as a result, these are often missed or mis-diagnosed (1,2). Plain ﬁlms may not be always available during magnetic resonance imaging (MRI) readout. MRI has increasingly become the preferred
Unfortunately, not all hemangiomas have the typical appearance, and they can mimic metastases on routine MR imaging. These are generally referred to as atypical hemangiomas and can result in misdiagnosis and ultimately additional imaging, biopsy, and unnecessary costs. Magnetic resonance imaging (MRI) with contrast enhancement currently is the procedure of choice, because MRI is more sensitive and specific than other imaging modalities in determining the presence, location, and number of metastases.

24 Jan 2018 Bone metastases are often multiple at the time of diagnosis. whether a predominant lytic, sclerotic, or mixed pattern is seen on radiographs.
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.

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.
It usually occurs at the time of initial diagnosis of sarcoidosis, but may in very rare cases appear many years after presumed resolution of thoracic sarcoidosis. • MRI effectively detects early metastases confined to the marrow, extent of disease in marrow, soft tissue extension from bone, and epidural extension.
