Femoral and popliteal aneurysms:
Diagnosis
(Professional Guide to Diseases (Eighth Edition))
Diagnosis is usually confirmed by bilateral palpation that reveals a pulsating mass above or below the inguinal ligament in femoral aneurysm. When thrombosis has occurred, palpation detects a firm, nonpulsating mass. Arteriography or ultrasound may be indicated in doubtful situations. Arteriography may also detect associated aneurysms, especially those in the abdominal aorta and the iliac arteries. Ultrasound may be helpful in determining the size of the popliteal or femoral artery.

Aneurysm, cerebral:
Diagnosis
(Handbook of Diseases)
With cerebral aneurysm, diagnosis is based on patient history; neurologic examination; a computed tomography (CT) scan, which reveals subarachnoid or ventricular blood; and magnetic resonance imaging or magnetic resonant angiography, which can identify a cerebral aneurysm as a “flow void” or by computer reconstruction of cerebral vessels.
Cerebral angiography remains the procedure of choice for helping to diagnose a cerebral aneurysm. Lumbar puncture may be used to identify blood in CSF when the CT scan is normal. However, its use is contraindicated in patients with signs of increased ICP.
Other baseline laboratory studies include a complete blood count, urinalysis, arterial blood gas (ABG) analysis, coagulation studies, serum osmolality, and electrolyte and glucose levels.

Aneurysms, femoral and popliteal:
Diagnosis
(Handbook of Diseases)
With femoral aneurysm, the diagnosis is usually confirmed by bilateral palpation that reveals a pulsating mass above or below the inguinal ligament. When thrombosis has occurred, palpation detects a firm, nonpulsating mass.
Arteriography or ultrasonography may be indicated in doubtful situations. Arteriography may also detect associated aneurysms, especially those in the abdominal aorta and the iliac arteries. Ultrasonography may be helpful in determining the size of the femoral or popliteal aneurysm.

aneurysm,ventricular:
Diagnosis
(Handbook of Diseases)
Persistent ventricular arrhythmias, onset of heart failure, or systemic embolization in a patient with left-sided heart failure and a history of MI strongly suggests a ventricular aneurysm. Indicative tests include the following:
Left ventriculography reveals left ventricular enlargement with an area of akinesia or dyskinesia (during cineangiography) and diminished cardiac function.
Electrocardiography may show persistent ST-T wave elevations after an MI.
Chest X-ray may demonstrate an abnormal bulge distorting the heart’s contour if the aneurysm is large; the X-ray may be normal if the aneurysm is small.
Noninvasive nuclear cardiology scan may indicate the site of infarction and suggest the area of aneurysm.
Echocardiography shows abnormal motion in the left ventricular wall.
