We present two cases of the Morning Glory Syndrome (MGS), with the most detailed MR images to date of this rare congenital optic nerve dysplasia. Though the embryology of this syndrome remains controversial, we feel the MR appearance can be diagnostic of the non-familial syndrome and be reliably distinguished from the similar appearing optic disc coloboma, which may be genetically inherited. MR imaging also allows the most sensitive detection and characterization of any associated intracranial anomalies, thus enabling more accurate determination of prognosis for the patient and their family.

Lemierre syndrome consists of septic thrombophlebitis of the internal jugular vein secondary to oropharyngeal infection, usually with Fusobacterium necrophorum. Septic metastatic emboli and distant infection are characteristic. We describe the imaging appearance of Lemierre syndrome in an adolescent female by both magnetic resonance imaging and computed tomography. This case illustrates the rapid onset and characteristic progression of the rare syndrome of Lemierre. In addition, we used magnetic resonance imaging to effectively distinguish between inflammatory venous thrombosis and abscess, thus avoiding surgery in our patient. Early directed antibiotic therapy is mandatory to ensure good outcome.

Various combinations of cranial remodeling techniques are used in an attempt to provide optimal cosmetic results and to reduce possible sequelae associated with craniosynostosis. One element of deformity that is difficult to correct directly is an overly flattened area such as that found in the parietal area in sagittal synostosis, unilaterally in lambdoid synostosis, or even in severe positional molding. The authors present a novel application for recontouring cranial bone, namely the multiple-revolution spiral osteotomy. The advantages of this technique include the avoidance of large areas of craniectomy and immediate correction of the cranial deformity. The surgical procedure, illustrative cases, early results, and apparent benefits of this technique are discussed.
