Bilateral accessory inferior turbinates and secondary middle turbinates.

Bifid inferior nasal turbinates-two inferior turbinates with a single root observed in the nasal cavity-are an extremely rare anatomical variation, especially when they are observed bilaterally and exist with other variations. We report a case of bilateral bifid inferior nasal turbinates with bilateral secondary middle turbinates. We discuss the findings of this rare condition and suggest an appropriate term-accessory inferior turbinate-to replace bilateral inferior turbinate by reason of its embryology.

Usefulness of the dynamic gadolinium-enhanced magnetic resonance imaging with simultaneous acquisition of coronal and sagittal planes for detection of pituitary microadenomas.

Objective: Does dynamic gadolinium-enhanced imaging with simultaneous acquisition of coronal and sagittal planes improve diagnostic accuracy of pituitary microadenomas compared with coronal images alone?

Methods: Fifty-six patients underwent 3-T sella MRI including dynamic simultaneous acquisition of coronal and sagittal planes after gadolinium injection. According to conspicuity, lesions were divided into four scores (0, no; 1, possible; 2, probable; 3, definite delayed enhancing lesion). Additional information on supplementary sagittal images compared with coronal ones was evaluated with a 4-point score (0, no; 1, possible; 2, probable; 3, definite additional information).
