Pseudotumor of the bladder as a manifestation of uncomplicated appendicitis.

We report the case of a 67-year-old woman who presented with an apparent bladder tumor and complaints of increased urinary frequency and postvoiding pain. Her diagnostic work-up revealed conflicting findings regarding the source of her bladder disease, and laparoscopy was required to make the final diagnosis of appendicitis. The presentation of appendicitis can be disguised and is often a difficult diagnosis.

Prospective evaluation of lesions of the mandible and maxilla: findings on multiplanar and three-dimensional CT.

The treatment of benign and malignant oropharyngeal diseases is greatly influenced by the degree of invasion of the mandible and maxilla. 3D DEN (Columbia Scientific, Inc., Columbia, MD) is a computer software program that reassembles data from a series of axial CT scans into cross-sectional oblique, three-dimensional, and panoramic CT reformations.

Nonaspiration fine-needle cytology of the liver: a new technique for obtaining diagnostic samples.

We studied a new method of obtaining diagnostic cytology samples from the liver that differs from fine-needle aspiration cytology in that no suction is used to obtain the sample. This method is simpler to perform than traditional aspiration biopsy and yields concentrated cell smears that are easier to interpret. The sample enters the needle because of capillary action, a physical property of fluid that causes it to flow into the lumen of a narrow channel.
