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 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 …

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.

The primary source is usually a carcinoma of the kidney, lung, breast, gastrointestinal tract, and thyroid . Sacral Metastases Aleksander Mika, BS Addisu Mesfin, MD Investigation performed at the (MRI) with and with-outcontrast17.Computedtomography (CT) helps to evaluate the degree of lytic or blastic involvement by the lesion. 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.

27 Dec 2013 Bony metastases from prostate cancer can widely affect the skeleton makes a radiologist ponder upon a meaningful differential diagnosis

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. 13 These cells produce lytic or blastic lesions. Lytic lesions involve the posterior cortex almost always with destruction of the posterior cortex and pedicle.

metastases cannot always be reliably differentiated with stan-dard MRI sequences because they can appear hypointense on T1-weighted images and heterogeneous on T2-weighted images. 2018-03-15 Metastases can be solitary or multiple, and they can be further subdivided into purely lytic, purely sclerotic, or mixed lesions. Osteolytic metastases are the most common, representing about 75% of all metastatic lesions.
