Validation of computed tomographic middle cerebral artery "dot"sign: an angiographic correlation study.
BACKGROUND AND PURPOSE The middle cerebral artery (MCA) "dot" sign consists of hyperdensity of an arterial structure, seen as a dot in the sylvian fissure. The MCA dot sign has been proposed to indicate thrombosis of M2 or M3 MCA branches, analogous to the hyperdense middle cerebral artery (HMCA) sign indicating M1 thrombosis. The MCA dot sign has not been validated previously against the gold ...
متن کاملMultiplanar computed tomography reconstruction to aid in recognition of the middle cerebral artery “Dot” sign: The sagittal string sign
While non-contrast head computed tomography is effective in detecting blood, it is not sensitive in diagnosing hyperacute ischemic stroke. One neuroradiologic marker for early thromboembolic occlusion of the distal middle cerebral artery is the middle cerebral artery "dot" sign. The "dot" seen on the typical axial plane represents a hyperdensity of the middle cerebral artery in the Sylvian fiss...
متن کاملHyperdense middle cerebral artery sign.
A 57-year old man presented with sudden onset hemiplegia. On examination he had global aphasia, a dense right hemiplegia and a right extensor plantar response. He had a history of diabetes mellitus, hypertension and a myocardial infarction one year ago. A non contrast CT scan of the brain done on the same day did not show a cerebral infarction, but showed a loss of visualisation of the insular ...

A 54-year-old woman presented to the emergency department with sudden onset severe headache, nausea and vomiting upon waking that morning. On examination, she was alert and oriented, with a mild right facial droop and a right upper extremity pronator drift. A non-contrast computed tomography (CT) of the head revealed diffuse subarachnoid blood, with a prominent triangular focus projecting into ...
متن کاملHyperdense middle cerebral artery sign after trauma.
© 2014 American Osteopathic Association A 56-year-old man presented to the emergency department after a highwayspeed, single-vehicle motor vehicle accident. Physical examination revealed no evidence of head trauma but was notable for a Glasgow Coma Scale score of 6, with the patient exhibiting a withdrawal response to pain on his left side. Computed tomography findings included a hyperdense mid...
