Incidental findings on cone beam computed tomography scans in cleft lip and palate patients.

Objectives: Cone beam computed tomography (CBCT) is frequently used in treatment planning for alveolar bone grafting (ABG) and orthognathic surgery in patients with cleft lip and palate (CLP). CBCT images may depict coincident findings. The aim of this study was to assess the prevalence of incidental findings on CBCT scans in CLP patients.

Incidental maxillary sinus findings in orthodontic patients: a radiographic analysis using cone-beam computed tomography (CBCT).

Unlabelled: To determine the frequency of incidental maxillary sinus findings using cone-beam computed tomography (CBCT) images made for orthodontic purposes.

Setting And Sample Population: One hundred thirty-nine consecutive CBCTs from 134 patients treated at the Department of Orthodontics and Dentofacial Orthopedics, University of Bern, Bern, Switzerland. Indications for CBCT imaging included the localization of impacted teeth and root resorption related to impacted teeth.

Suspected gouty tophus in a woman's breast.

A postmenopausal woman treated with diuretics for hypertension and who underwent surgery for a previous fibroadenoma of the left breast presented, in December 2003, with a sudden bloody discharge of the left nipple with local swelling, redness, and pain. Radiologic investigations revealed a well-delimited tumor under the areola. Needle aspiration disclosed many histiocytes but no bacteria.

[Calcium pyrophosphate dihydrate deposition disease in the transverse ligament of the atlas].

Calcium pyrophosphate dihydrate (CPPD) deposits, answerable for chondrocalcinosis, are frequently observed in elderly people. Involvement of the spine is not rare. We present the case of a woman hospitalised for an acute arthritis of the right knee related to CPPD crystal deposition disease who suffered from acute neck pain.

[Bilateral knee osteoarthritis associated with supracondylar chondromas and popliteal osteochondromas].

The knee is a complicated joint where various diseases can coexist. We present a case of a woman with bilateral knee osteoarthritis who's radiographic follow up allowed a 15 year watch of a bilateral medial supracondylar chondroma and of a popliteal osteochondroma of the both knees. This observation emphasizes the usefulness of repeated radiographs, not only in order to survey the evolution of the knee osteoarthritis but also to disclose the appearance and/or disappearance of other lesions in the neighborhood.
