  • Purpose: Cleidocranial dysostosis is a rare hereditary disorder affecting bones that develop by intramembranous formation. The typical features include excessive growth of transverse diameter of the skull, hypoplastic clavicles, low height and characteristic facial features. Methods: A 28 years old female patient visited by frontal area depression. The diagnosis was performed by computed tomographic study and radiographic imaging. The patient has widely opened anterior fontanelle, partial fused metopic suture, multiple wormian bone and supernumenary impacted teeth. Under the coronal incision, we exposed depressed frontal area and corrected with Medpor block carving. Results: Postoperatively, frontoparietal skull was aestheticlly improved and she was satisfied with the results. Conclusion: Authors report a case of cleiodocranial dysostosis who has been done correction of abnormal skull shape by Medpor$^{(R)}$ insertion.

  • Substernal goiter may be defined as any thyroid enlargement that has 50 to 100 % of its mass inferior to the thoracic inlet. Ectopic substernal goiters are rare, and most substernal gaiters arise from cervical thyroid gland. Fifteen to fifty percent of these patients are asymptomatic. Symptoms, when present, are usually the result of tracheal or esophageal compression. Symptoms are often positional. Standard chest roentgenograms are often diagnostic, but computed tomographic or radioactive iodine scans may be helpful. In symptomatic patients or those in whom explorations are undertaken for diagnostic purpose or exclude carcinoma, surgical removal is indicated. Although cervical thyroids with substernal extension may be safely and successfully removed through a cervical incision, primary substernal goiters by definition derive their blood supply from within the thorax and are better approached by splitting the sternum or through a posterolateral thoracotomy. Recently we experienced a child fist sized secondary posterior mediastinal goiter in 55-year old female. The mass was completely removed through right posterolateral thoracotomy without any complications. The postoperative courses were uneventful.

  • One of the most lethal forms of mediastinitis is descending necrotizing mediastinitis, in which infection arising from the oropharynx spreads to the mediastinum. Despite the development of computed tomographic scanning to aid in the early diagnosis of mediastinitis, the past 30 years, in large part because of continued dependence on transcervical mediastinal drainage, Although transcervical drainage is usually effective in the treatment of acute mediastinitis due to a cervical esophageal perforation, these approach in the patient with descending necrotizing mediastinitis fails to provide adequate drainage and pre-disposes to sepsis and a poor outcome. In addition to cervical drainage, aggressive, early mediastinal exploration - debridement and drainage through a subxiphoid incision or thoracotomy - is advocated to salvage the patient with descending necrotizing mediastinitis.

  • Primary malignant lymphomas of the lung are rare neoplasms representing 3.6% of all extranodal lymphomas and less than 1% of pulmonary malignancies, with its distinct clinicopathological features. A 60-year-old symptomatic man, who was a former non-smoker, had a cough and sputum. Chest roentgenogram and computed tomographic scan showed the presence of a posterior mass in the basal segment of the right lung. Transthoracic needle aspiration cytology was inadequate for the diagnosis of cancer. A subsequent right thoracotomy was carried out, which showed a primary pulmonary lymphoma of the bronchus-associated lymphoid tissue.

  • Pneumomediastinum, also referred to as mediastinal emphysema or Hamman's syndrome, is defined as the presence of air or gas within the fascial planes of the mediastinum. Superior extension of air into the cervicofacial subcutaneous space via communications between the mediastinum and cervical fascial planes or spaces occurs occasionally, Pneumomediastinum frequently results from blunt tracheobronchial lesions and esophageal injuries. However, in most cases, the origin of pneumomediastinum remains unclear. an some cases, it is attributed to the Macklin effect. We report a case of patient with pneumomediastinum, that presented with Macklin effect on chest computed tomographic scan.

  • The purpose of this paper is to review our experience with mucoepidermoid carcinoma(MEC), a rare tumour in minor salivary glands, in a paediatric patients. 15-year-old boy was noted to have a irregular round mass appearing atthe soft palate just to the right of the mid-line. A computed tomographic(CT) scan showed a palatal mass limited to soft palate with no bony erosion. The lesion was curetted and debulked. Pathology was reported as an intermediate-grade mucoepidermoid carcinoma, and the patient was considered to radiation therapy institution for further treatment. To date, patients remain free of disease. Wide local excision is the treatment of choice for low to intermediate grade MEC of the minor salivary glands in paediatric patients.

  • Isolated hypoglossal nerve paresis due to mechanical compression from a vascular lesion is very rare. We present a case of a 32-year-old man who presented with spontaneous abrupt-onset dysarthria, swallowing difficulty and left-sided tongue atrophy. Brain computed tomographic angiography and magnetic resonance imaging of the brainstem demonstrated an abnormal course of the left vertebral artery compressing the medulla oblongata at the exit zone of the hypoglossal rootlets that was relieved by microvascular decompression of the offending intracranial vertebral artery. This case supports the hypothesis that hypoglossal nerve palsy can be due to nerve stretching and compression by a pulsating normal vertebral artery. Microvascular decompression of the intracranial nerve and careful evaluation of the imaging studies can resolve unexpected isolated hypoglossal nerve palsy.

  • We report a case of trigonal cavernous malformation (CM) radiologically mimicking meningioma. The computed tomographic (CT) head angiography and magnetic resonance imaging (MRI) showed a partially calcified lesion with slight contrast enhancement located in the area of the left atrium of lateral ventricle. The lesion was completely removed using microsurgery with a parieto-occipital transcortical approach. The resected mass was histologically confirmed as CM. CM should be considered as differential diagnosis in case of the atrial mass lesion due to lack of hemosiderin ring characteristically seen other seated CM.

  • A 28-year-old woman was referred to our hospital with a sudden, very severe headache. Brain computed tomographic angiography showed a saccular cerebral aneurysm at the bifurcation of the left middle cerebral artery and infraoptic courses of both anterior cerebral arteries. The anterior cerebral arteries were seen to arise from the ipsilateral internal cerebral arteries at the level of the origin of the ophthalmic artery, passed underneath the ipsilateral optic nerve, and turned upward at ventral portion of the optic chiasm. Infraoptic course of the proximal anterior cerebral artery is an extremely rare anomaly and is often associated with cerebral aneurysms. We report the clinical features, radiological findings, and possible genesis of this anomaly with a literature review.

  • Three-dimensional reconstruction of computed tomographic image(3D CT) is a well-established imaging modality which has been investigated in various clinical settings. It is commonly performed in case of congenital or developmental abnormalities, and traumatic fracture of skull and face that requires reconstruction of osseous structure. However reporting the 3D CT in laryngeal or tracheal stenosis is rare and its results are obscure. The authors performed 3D CT in six cases of tracheal stenosis and found diagnostic value of 3D CT. A Comparision of diagnostic information obtained from plain X-ray, 2D CT and 3D CT has performed in total six cases of tracheal stenosis. Surgical treatment of the tracheal stenosis was following in these cases : tracheal end to end anastomosis In 1 case, laryngotracheal end to end anastomosis in 2 cases. 3D CT information was compared with operative finding. In two of six cases, satisfactory information was not obtained from 3D CT in evaluating an exact stenosis of trachea. Future, it will be helped in evaluating of tracheal stenosis by 3D CT.
