Diagnostic Examinations and Findings

Test	Day of Hospital Course	Result
Computed tomography of the head without contrast	1	Mixed density right subdural hematoma with chronic and acute elements Left midline shift of 1.1 cm
Magnetic resonance imaging of the head without contrast	1	Right subdural hematoma overlying frontal, parietal, and temporal lobes with 5.8-cm left midline shift Small mixed-signal left epidural hematoma over left parietal lobe
Magnetic resonance angiography/venography of the neck	1	Normal blood flow
Computed tomography of the head without contrast	2	Interval worsening of sulcal effacement throughout the right cerebral hemisphere with concerns for loss of gray-white differentiation Interval decrease in right subdural hematoma and left epidural hematoma after surgery
Electroencephalogram	2	Multiple electrographic seizures with generalized onset, interictal epileptiform discharges with generalized spike waves, and generalized periodic discharges
Computed tomography angiogram of the head and neck	3	New anterior mediastinal soft tissue density with an irregular appearance along left internal mammary artery, suspicious for a pseudoaneurysm with minimal active bleeding Consolidation within the superior segment of the left lower lobe
Diagnostic angiography	4	Aneurysmal dilatation, segmental narrowing, and web formation of the left internal mammary artery
