Postoperative imaging of labyrinthine fistulae in cholesteatomas.
We evaluated the morphology of three operatively closed labyrinthine fistulae which were due to acquired middle ear cholesteatoma in three patients. In all three cases the fistula location was in the horizontal semicircular canal. The fistulae were closed by a mixture of bone powder and Tissucol. The layer closing the fistula was in all cases indistinguishable from the bony otic capsule on the postoperative CT.
[Technique and interpretation of arthrography of the temporomandibular joint. Study of 120 cases].
The goal of the study was to assess the predictive value of inferior joint space arthrography for detection of abnormalities found during surgery. Therefore, a retrospective analysis of arthrographic and surgical findings in 120 joints was performed. Arthrography showed high accuracy for detection of anterior disk displacement (90%) and disk perforation (90.8%). The shape of the anterior recess proved to be the most valuable arthrographic criterium for detection of anterior disk displacement. Cinematographic registration of joint dynamics after injection of contrast material and arthrotomographic analysis of the shape of the superior margin of the anterior recess of the inferior joint space were necessary for an optimal evaluation of the disk position.
Congenital arterial anomaly in the middle ear presenting as a glomus tumor.
A case of congenital agenesis of the cervical internal carotid artery with rerouting via the inferior tympanic artery and the embryonic hyoid artery to the horizontal internal carotid artery is presented. At otoscopy the anomaly simulated a glomus tumor. CT scan, by demonstration of the absence of the vertical portion of the carotid canal, the enlargement of the inferior tympanic canaliculus, and the soft tissue mass within the middle ear in continuity with the horizontal internal carotid artery, diagnosed the anomaly very accurately.
Extranodal non-Hodgkin lymphoma of the head and neck presenting as a mandibular swelling: report of two cases.
We report two cases of extranodal extralymphatic non-Hodgkin lymphoma presenting as a mandibular swelling. In one case the masseter muscle was involved, suggestive of a non-epithelial process. In the other case the mandible was involved by a mixed osteolytic bone process. Extranodal non-Hodgkin lymphoma should be considered when dealing with a mass lesion in the masticator space.
Temporomandibular joint imaging.
Pain and discomfort caused by internal derangement of the temporomandibular joint are frequent in our society. Patients can present with very divergent complaints, not always clearly related to the temporomandibular joint. Good imaging studies of the temporomandibular joint that can show the presence or absence of a problem and give an idea as to type of disease and its seriousness are, therefore, necessary. The choice of which imaging study to use largely depends on whether MR imaging is easily available. Ongoing investigations show that MR imaging of the temporomandibular joint not only depicts the soft tissue derangements very well, but also shows the associated bony changes. However, the exact significance of disk displacement is not always clear because anterior displacement is also seen in asymptomatic volunteers and after clinically successful treatment.

New trends in computed tomography of the head and neck.
Pathology in the head and neck region is now often examined using MR imaging. However, CT remains a very valuable tool for staging of tumors and lymph nodes in the pre- and postoperative periods. In cases of sinusitis, CT has completely replaced conventional radiography. Moreover, CT helps in differentiating hypointense spots seen in the paransal sinuses on MR. In dental radiology, CT is superior to pantomography in detecting root resorption due to impacted teeth. Thanks to the development of new scanners, three-dimensional reconstructions are possible and scanning times are reduced.

Computed tomography of the normal and pathologic muscular system.
A standard program of computed tomographic (CT) scanning of the human skeletal muscular system was developed. Scans were obtained on five levels: the neck, the shoulder girdle, the pelvic girdle, the thigh, and the lower leg. The normal size and density of several muscles were determined. CT scans were also obtained in patients with various neuromuscular diseases. Several types of lesions were found, and their morphologic descriptions and quantitative data are presented. It is concluded that CT opens new possibilities for the evaluation of muscular atrophy and hypertrophy.

Computed tomography of the human skeletal muscular system.
A description of different levels of the normal adult human skeletal muscular system is given as derived by computed tomography (CT). A standard program is presented by which a maximum number of muscles which are affected by neuromuscular diseases can be examined with a minimum of radiation. Twenty-four patients of different ages, 12 males and 12 females, were examined. Descriptions of different levels of the skeletal muscular system, with measurements of cross-section and density of a number of important marker muscles are presented. Variations of these parameters with age, sex, and cerebral dominance are discussed. It is concluded that CT scans can greatly enhance our insight into the effects of neuromusclar diseases on normal and abnormal skeletal muscles.

Computed tomography of muscle.
Computed tomography (CT) scans of skeletal muscles of 3 patients with pseudohypertrophic muscular dystrophy are presented. Different patterns of muscle alterations and particularly of pseudohypertrophy are described. The significance of the radiological findings for clinical examination, electromyography, and needle biopsy is discussed.
Resorption of the lateral maxillary incisor: assessment by CT.
Computed tomography of the maxillary alveolar arch was performed in three children with delayed eruption of one or both maxillary cuspids. Computed tomography demonstrated close contact between the ectopically localized and nonerupted canine and the lateral incisor. The lesion was unilateral in two patients and bilateral in one. In two patients resorption of the lateral incisor root was demonstrated. Moreover, CT permitted exact determination of the extent of the lesion by differentiating between superficial cementodentine resorption limited to the cementodentine (superficial resorption) and resorption extending into the pulpal canal (pulpal canal involvement).
