[en] Primay melanoma of the cavernous sinus is very rare with only few cases reported in the literature. We present the cross-sectional imaging findings of this rare tumor. The differential diagnosis for cavernous sinus mass lesion is wide as it contains vital neurovascular structures that may be affected by vascular, neoplastic, infective, and infiltrative lesions arising in the cavernous sinus proper or via extension from adjacent intra and/or extracranial regions. Radiologic imaging can narrow the differential diagnosis, however, imaging cannot definitely reach single diagnosis if they present in atypical form with hemorrage and cystic degeneration. This case report illustrates that primary cavernous sinus melanoma may present as a atypical tumor with diagnostic dilemma.
[en] The majority of the meningioma is benign. But local invasion by meningioma is not uncommon, which is usually restricted to dura and venous sinuses and may extend to the calcalium and scalp. Distant metastasis from meningioma is extremely rare. Since power(1886) has reported the lung metastasis of meningioma, about 60 cases of extracranial metastasis has been reported until now. We found a case of angioblastic meningioma involving olfactory groove with extracranial metastasis to thoracic and lumbar vertebrae, scapula, rib and right frontal bone.
[en] This study was performed in order to analyse the morphology of maxillary sinus on orthopantomogram. The author analysed the anterior-posterior width of mesial wall, the extension of anterior margin in maxillary sinus and the interrelation between the root apex of maxillary 1st molar and sinus floor. The films consisted of 514 orthopantomograms divided into three groups ranging the 3rd decade, 4th and 5th decade and 6th decade. The obtained results were as follows: 1. The mean dimensions of the anterior-posterior width of mesial wall were 43.81 ± 4.55 mm for male and 43.80 ± 4.49 mm for female in the right of maxillary sinus, 43.75 ± 4.74 mm for male and 43.37 ± 3.92 mm for female. 2. With age, the dimensional change of the anterior-posterior width of mesial wall in maxillary sinus was not observed. 3. The extension order of anterior margin of the maxillary sinus was distal to canine side, 1st premolar mesial side, canine mesial side, and 1st premolar distal side. 4. In the distance between the root apex of upper 1st molar and the maxillary sinus floor, the degree of closeness was more increased in the older-aged group than in the younger-aged group.
[en] The antrolith is a rare disease in the maxillary sinus. We experienced a 67-year-old female whose chief complaint was an intermittent dull pain of clinical, radiological and histological findings, we diagnosed it as antrolith in the left maxillary sinus and obtained results as follows: 1. Three radiopaque substances in the left maxillary sinus were revealed as 'Antroliths'. 2. These antroliths were movable in the left maxillary antrum and combined with maxillary sinusitis. 3. We supposed it internal origin of nidus in this case.
[en] This study was designed to investigate the effects of the maxillary sinus development and nasal septum deviation on diseases of maxillary sinus with cleft palate. The materials was 152 cephalometric Waters' projections consist of 76 cleft patients and 76 normal subjects. The results were as follows: 1. The disease of maxillary sinus was present in 49% of a cleft group and 14% of a control group, and prevalent in cleft side. 2. It showed no statistically significant difference in size of the maxillary sinus in cleft palate patients compared to the control population and in the cleft side to the noncleft side (p<0.05). 3. Nasal septum deviation was more severe in the cleft patient its average value was 3.55mm, compared to the control group, 0.99 mm (p<0.01) and 77% of the deviated nasal septum was deviated to the cleft side.
[en] Congenital coronary artery fistula (CCAF) is communication of a coronary artery or its main branch with one of the atria or ventricles, the coronary sinus, the superior vena cava, or the pulmonary artery. In Korean peoples, only 4 cases of the CCAF were reported as rare as worldwide and authors want to report another case of CCAF, confirmed by operation. 10-year-old girl shows a fistula between sinus node artery of the right coronary artery and right atrium on root aortogram with left-to-right shunt and Qp/Qs=1.58, in which simple ligation of the sinus node artery from right coronary artery was performed. All of the 5 Korean CCAF (4 were previously reported and 1 of authors) were originated from right coronary artery, and of which 4 were opening into right ventricle and 1 of authors were into right atrium. Associated cardiac anomaly was noted in only 1 case as single coronary artery. Ages were from 9 months of age to 10 years old and no adult left case were found. 3 were female and 2 were male patients.
[en] The author have observed mucoid retention cyst in the right maxillary sinus of the patient, 41 year old woman, complained discharging of purulent exudate on the right maxillary molar area, and obtained the following conclusions; 1. The mucoid retention cyst in maxillary sinus casts a faint dome shaped shadow into the radiolucent image of maxillary sinus. 2. The mucoid retention cyst in maxillary sinus may occurred without the history of trauma. 3. Intraoral standard films are also valuable for the interpretation of the lesions in maxillary sinus but only extraoral roentgenograms.
[en] Radiographic features of maxillary sinusitis, type of mucosal thickening, types of bony wall change, and relationship between the radiographic features and symptoms of patients were observed and classified in the Waters' view of 360 patients with 441 maxillary sinuses demonstrating radiologic change was observed in the 154 periapical films. Finally, the value of orthopantomography in the diagnosis of maxillary sinusitis was evaluated in the 138 cases, The obtained results were as followings. 1. Among 441 maxillary sinuses examine by Waters' projection, mucosal thickening was seen in 56.7% and generalized opacification was seen in 36.3%. 2. Among 270 mucosal thickenings classified 8 types, overall regularly thickened type cortical plates was the highest in incidence (36.3%). 3. Bony wall change was seen in 35.6% of all cases and the indistinct while line of the cortical plates was the highest in incidence (78.2%) among the 6 types. 4. Pain (419%) and pus discharge (21.0%) were the most frequent symptoms. And pus discharge, foul odor, and headache was more prevalent in type of generalized opacification than any other types. 5. Regular pneumatization involving all roots of premolars and molars was the highest in incidence (55.0%). The first molar presented the most frequent involvement (61.0%). 6. In orthopantomography, 46.4% showed apparent increased radiopacity and 23.9% showed suspicious increased radiopacity in comparison to Water's projection.
[en] The purpose of this study was to investigate the incidence of the types of the panoramic innominate lines in panoramic radiographs of the patients who had no pathoses in the maxillary sinus and adjacent bony structures. And all panoramic radiographs were obtained in standard position. And the following results were observed; Panoramic innominate lines were observed various types of vertical lines running across the outer third of the maxillary sinus in all examined panoramic radiographs. And types of them were similar in the right and left side of each patient. The types of the panoramic innominate lines were observed most frequently as concavetype (69.3%), followed by convex type (12.5%), flat type (9.0%), uneven type(8.3%), and obliterated type (1.3%) in descending order of frequency. According to the age and sex, concave type was also observed most frequently in all examined radiographs.
