Case of the Week
I would like to thank Dr Castillo for providing me the opportunity to be the section editor for the AJNR Case-of-the-Week (COW). It has been about 4 months since I assumed this responsibility and, I would also like to take this opportunity to thank colleagues from all over the world toward their contribution to the COW.
It has been about 2 – 3 years since COW was introduced by Dr Castillo. It has grown to be a tremendously popular site (sometimes receiving up to 10,000 views per month). With the hope of adding to the educational content of COW, Dr. … Continue reading >>
Neonatal Pituitary Gland
This is a one month-old female with congenital hypothyroidism, hypoplasia of the thyroid gland, elevated TSH (eight times normal value), elevated FSH and LH (four times normal values), normal GH, without diabetes insipid. She is now being treated for the hypothyroidism, and we are waiting for hormonal follow-up; MRI follow-up in three to six month follow-up.
Has anyone an explanation for the focal bright spot on T1-weighted images in the cranial portion of the pituitary stalk, just down the median eminence, in the presence of a normal neurohypophysis?
Is it an “ectopic” adenohypophysis?
Is this a thin pituitary stalk in … Continue reading >>

RE: DWI for Head and Neck Lesions – Acute Ischemic Optic Neuropathy
Here’s another case for the value of DWI for head and neck lesions.
This patient had left central retinal artery occlusion and acute ischemic optic neuropathy. There is restricted diffusion in the anterior left optic nerve which is much more obvious than the mild perineural enhancement on coronal postcontrast images.
Cases of the Week
The case of the week feature is very popular. We now have over 18 months of cases accumulated. Every week, more than 5000 individuals (at times as close to 8000!) look at them. The database can be searched by diagnosis and or blindly by date of posting. The cases are illustrative and their degree of difficulty varies making them interesting for individuals with all levels of knowledge in neuroradiology. It is my desire, that residents and fellows will used them to study. Submissions are open only to fellows in Neuroradiology. Since AJNR and other journals accept very few case reports, … Continue reading >>
