Malignant cells invade the brain parenchyma mostly via
Correct!
Wrong!
Malignant cells invade the brain parenchyma mostly via Virchow-Robin spaces
Perivascular spaces, also known as Virchow-Robin spaces, are fluid-filled spaces that surround small arterioles, capillaries
Leptomeninges includes
Correct!
Wrong!
Meninges - three layers are the dura, arachnoid, and pia
Dura mater - pachymeninges
dura mater is known as the patchy-meningeal layer.
Arachnoid and pia meningeal layers are called the leptomeninges
What is the referred treatment option for solitary brain metastasis?
Correct!
Wrong!
Many studies indicate that the risk of Carcinomatous Meningitis is 2.81 times more with piecemeal resection than in en-bloc resection.
Most common hematological malignancies causing leptomeningeal metastasis
Correct!
Wrong!
B-cell lymphoma is the most common etiology for hematological malignancies causing leptomeningeal metastasis
Austrian syndrome is a triad of all of the following EXCEPT
Correct!
Wrong!
Austrian syndrome
Austrian syndrome is a rare triad of endocarditis, meningitis, and pneumonia
Austrian syndrome is a rare triad of endocarditis, meningitis, and pneumonia caused by Streptococcus pneumonia described by Robert Austrian in 1956
