Does prostate cancer affect your brain?

Brain metastasis is rare in prostate cancer and occurs late in the course of the disease. It usually represents the failure of hormone-deprivation therapy and the presence of disseminated disease.

Does restricted diffusion mean cancer?

Although the causes for restricted diffusion are many, for malignant tumors such as glioblastomas, medulloblastomas, or lymphomas, the dominant factor contributing to tumor-related diffusion restriction is thought to be related to regions of increased cellularity.

What is restricted diffusion prostate?

Prostate cancer results in increased cellularity, and a reduction of the extracellular space, and results in restricted diffusion on DWI. The strength and duration of the diffusion gradient detected are referred to as “b-values” with higher values resulting in the production of a higher signal intensity (Figure 4A).

When does prostate cancer spread to the brain?

The median time from the initial diagnosis of prostate cancer to the discovery of brain metastases on MRI was 3.8 years (range . 6-19.7 years). All 21 patients with parenchymal brain metastases from prostate cancer died by last follow-up performed in January 2011.

What does restricted diffusion in the brain mean?

Cerebral cortical restricted diffusion or gyriform restricted diffusion refers to curvilinear hyperintense signal involving the cerebral cortex on DWI images with a corresponding low signal on ADC images. Causes include: vascular thrombo-occlusive disease (most common) 1. cerebral venous thrombosis.

Is restricted diffusion good or bad?

Bacterial abscesses and empyemas reliably demonstrate restricted diffusion, and DWI has proved useful in distinguishing abscesses from necrotic tumors, resolving hematomas, and other fluid-filled cavities.

How long can you live with prostate cancer that has spread?

Once prostate cancer has spread beyond the prostate, survival rates fall. For men with distant spread (metastasis) of prostate cancer, about one-third will survive for five years after diagnosis.

How often does prostate cancer spread to the brain?

The incidence of brain metastasis in the prostate cancer patients with systemic metastases elsewhere in the body was .38%. Of the 13,547 patients with prostate carcinoma, the overwhelming majority (99.4%) had the adenocarcinoma subtype (n = 13,470).

Are there any cases of restricted diffusion in cancer?

Restricted diffusion was observed in a total of 15 metastatic lesions (19, 7%). Primary malignancy was lung carcinoma in 10 of these cases (66, 6%) (5 small cell carcinoma, 5 non-small cell carcinoma), and breast carcinoma in three cases (20%).

How are brain metastases diagnosed in prostate cancer patients?

At the time of brain metastasis detection, 95% of the patients had concurrent osseous metastases, 86% lymph node metastases, and 76% liver and/or lung metastases. Brain metastases were multifocal in 71% of patients, hemorrhagic in 33%, diffusion restricted in 19%, and partially cystic/necrotic in 19%.

How many prostate cancer patients have brain MRI?

The patients with metastatic disease were identified utilizing ICD-9 and CPT codes. Of the 13,547 prostate cancer patients, 811 had brain imaging. There were 540 patients that had a brain MRI, 510 that had a head CT, and 239 that had both.
