Contrast Enhanced MR for Acute Appendicitis in Children
The past 9 months have been extremely busy and I haven’t been able to be as active as I would like on RadiologyPics.com, but now I can finally share why. With the help of my co-authors John H. Naheedy and Peter G. Kruk, we published an article in Pediatric Radiology entitled “Diagnostic Performance of Contrast Enhanced MR for […]
How to Become a Radiologist – More than 13 years in the making
So you want to become a radiologist? Curious as to what it takes? If so, read below…. Radiologists are physicians who use cutting-edge technology in medical imaging studies to diagnose disease. The training is lengthy, just like any other sub-specialty area in medicine. Lets start from the beginning (disclaimer: the below paragraphs will detail the […]
Acute Pulmonary Embolism
History: 55 year old male with shortness of breath This is a case of acute pulmonary embolism. A pulmonary embolism is a blood clot which travels via the heart into the arteries that supply blood to the lungs. Typically the blood clot arises from the lower extremities, what is known as a deep vein thrombosis. […]
Metastatic Neuroblastoma
History: 6 year old male with abdominal pain Unfortunately, this is a case of metastatic neuroblastoma in a 6 year old male which was diagnosed initially on MRI. Neuroblastoma is the most common extracranial solid malignancy in children, and the third most common overall cancer in children. They most commonly arise from the adrenal medulla […]
Perforated Appendicitis MRI
History: 16 year old with abdominal pain This is a case of perforated appendicitis. Appendicitis usually occurs due to obstruction of the appendix at its origin from the cecum, in this case due to an appendicolith. This causes build up of secretions and mucus within the lumen of the appendix, which then dilates. The resultant […]
Bicornuate Uterus with Hematometrocolpos and Hydrosalpinx
History: 13 year old female with pelvic pain This is a case of a bicornuate uterus with hydrosalpinx of the right fallopian tube. Read about Imaging of Mullerian Duct Anomalies. Uterine didelphys ultrasound.
Ovarian Dermoid Cyst MRI
History: 14 year old female with right lower quadrant pain This is the appearance of an ovarian dermoid cyst on MRI, also known as a mature teratoma. The name teratoma gives a clue as to the histology of the dermoid cyst, usually containing parenchymal cell types from all three germ cell layers (mesoderm, endoderm, and […]
MRI for Pediatric Acute Appendicitis
History: 14 year old female with right lower qaudrant pain This is the appearance of pediatric appendicitis on MRI. Intravenous gadolinium contrast aids in visualization of the appendix (as seen in the third image above, the LAVA-Flex sequence MRI). MRI has recently been a hot topic of research in the diagnosis of pediatric appendicitis in […]
Neonatal Onset Multisystem Inflammatory Disorder
History: Not moving left leg, flexion contracture at the knee. Other past medical history includes hyperbilirubinemia at birth, autoimmune hepatitis, sensorineural hearing loss and global developmental delay. Neonatal Onset Multisystem Inflammatory Disease (NOMID) was first described by Prier and Griscelli in 1987 and has also been referred to as chronic infantile neurologic, cutaneous and articular syndrome (CINCA). It is a rare genetic disorder on the spectrum of cryopyrin associated periodic syndromes (CAPS). NOMID is […]
Child Swallows Mickey Mouse – The Mickey Mouse Sign
History: Parent concerned child swallowed a “foreign body.” This is what I’ve termed a “pseudo-Mickey Mouse sign,” as there are many other real Mickey Mouse signs in radiology. For example, anencephaly (see below), progressive supranuclear palsy, outward flair of the iliac wings in Down Syndrome, radiotracer uptake in the pedicles on bone scan for Paget’s […]
