Aunt Mickey (They Look the Same until You Undress Them). Internal Capsule Infarct or Something Else?
This 30 year old hypertensive female smoker presented with acute onset of right hemiparesis. Her history also included OCP use and dyslipidemia. MRI demonstrated an acute infarct in the posterior limb of the left internal capsule. ADC maps showed corresponding low ADC values. MR angiography, echocardiography, and lower extremity venous ultrasound were all normal.
Seven months later the patient re-presented to the ED with persistent waxing and waning hemiparesis, peripheral loss of sensation, and worsening ataxia. MRI at this admission demonstrated resolution of diffusion abnormalities in the left internal capsule but new right hemispheric lesions. The more inferior lesion was associated with … Continue reading >>
Aunt Mickey (They Look the Same until You Undress Them). Nerve Sheath Tumor or Something Else?
Aunt Mickeys are alternative diagnoses for “Aunt Minnies”. They represent less common diagnoses, and emphasize the importance of clinical history and careful imaging review.
Dumbell spinal mass: Nerve sheath tumor or something completely different?
A “dumbell” spinal mass was discovered during CT angiographic evaluation of an aortic aneurysm in this 66-year-old female. She had experienced constant but stable low back pain. There were no neurologic deficits.
The lesion was biopsied under CT guidance. At pathology, the lesion was composed of closely apposed small to medium sized blood vessels (some of which contained organizing thrombus) without intervening stroma. The vessels were … Continue reading >>
Aunt Mickey (They Look the Same until You Undress Them). Colloid Cyst or Something Else?
Aunt Mickeys are alternative diagnoses for “Aunt Minnies”. They represent less common diagnoses, and emphasize the importance of clinical history.
This submission is a 23 year old male patient who became lethargic and somnolent after playing soccer. On physical exam he was somnolent, but arousable with no focal neurologic deficits. An unenhanced CT of the brain initially demonstrated right frontal horn dilatation. A subsequent CT demonstrated bilateral lateral and third ventricular dilatation. Following placement of a ventriculostomy catheter, MRI was obtained and demonstrated a cystic-appearing third ventricular lesion. The lesion was hyperintense on T1WI (Fig 1) and hypointense on T2WI … Continue reading >>
