Diagnostic Examinations and Findings

TestDay of Hospital CourseResult
Computed tomography of the head without contrast1Mixed density right subdural hematoma with chronic and acute elements Left midline shift of 1.1 cm
Magnetic resonance imaging of the head without contrast1Right 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 neck1Normal blood flow
Computed tomography of the head without contrast2Interval 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
Electroencephalogram2Multiple electrographic seizures with generalized onset, interictal epileptiform discharges with generalized spike waves, and generalized periodic discharges
Computed tomography angiogram of the head and neck3New 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 angiography4Aneurysmal dilatation, segmental narrowing, and web formation of the left internal mammary artery
