Easily detected signs of perineural tumour spread in head and neck cancer.

Jan Willem Dankbaar, Frank A Pameijer, Jeroen Hendrikse, Ilona M Schmalfuss,

Perineural tumour spread (PNTS) in head and neck oncology is most often caused by squamous cell carcinoma. The most frequently affected nerves are the trigeminal and facial nerves. Up to 40% of patients with PNTS may be asymptomatic. Therefore, the index of suspicion should be high when evaluating imaging studies ... Read more >>

Practical Tips for MR Imaging of Perineural Tumor Spread.

Claudia F E Kirsch, Ilona M Schmalfuss,

Perineural tumor spread (PNS) substantially alters a patient's prognosis and treatment plan. Therefore, it is critical that the radiologists are familiar with the course of cranial nerves commonly affected by PNS and the neuronal connections to appropriately map the extent of PNS. Limited involvement of a nerve by PNS might ... Read more >>

Petrous apex.

Ilona M Schmalfuss,

The petrous apex is the most medial portion of the temporal bone that cannot be directly examined on clinical examination. The referring physician completely relies on imaging and radiologic interpretation. Unfortunately, the petrous apex displays anatomic variations such as asymmetric pneumatization that might be mistaken for underlying lesions. The location ... Read more >>

Pituitary abnormalities in Prader-Willi syndrome and early onset morbid obesity.

Jennifer L Miller, Anthony P Goldstone, Jessica A Couch, Jonathan Shuster, Guojun He, Daniel J Driscoll, Yijun Liu, Ilona M Schmalfuss,

Prader-Willi syndrome (PWS) is a well-defined syndrome of childhood-obesity which can serve as a model for investigating early onset childhood obesity. Many of the clinical features of PWS (e.g., hyperphagia, hypogonadotropic hypogonadism, growth hormone deficiency) are hypothesized to be due to abnormalities of the hypothalamus and/or pituitary gland. Children who ... Read more >>

Skull base: pseudolesion or true lesion?

Ilona M Schmalfuss, Morgan Camp,

The skull base is a complex anatomical structure. Therefore, radiologists often use "side-to-side" comparison for detection of abnormalities. This approach is compromised by the high frequency of anatomical variations involving the skull base and the common presence of flow-related artifacts within vessels at the skull base that might mimic true ...

Reward context sensitivity impairment following severe TBI: an event-related potential investigation.

Michael J Larson, Kiesa G Kelly, David A Stigge-Kaufman, Ilona M Schmalfuss, William M Perlstein,

Many rehabilitation protocols following traumatic brain injury (TBI) utilize reinforcement and reward to influence behavior and facilitate recovery; however, previous studies suggest survivors of severe TBI demonstrate impairments in contingency utilization and sensitivity. The precise neurobiological mechanisms underlying these deficits have not been thoroughly explored, but can be examined using ... Read more >>

Performance monitoring, error processing, and evaluative control following severe TBI.

Michael J Larson, David A S Kaufman, Ilona M Schmalfuss, William M Perlstein,

Patients with severe traumatic brain injury (TBI) often demonstrate impairments in performance monitoring--an evaluative control process that can be measured using the error-negativity/error-related negativity (Ne/ERN) and post-error positivity (Pe). The Ne/ERN and Pe are event-related potential (ERP) components generated following errors, with current theories suggesting the Ne/ERN reflects automatic performance ... Read more >>
