To evaluate characteristic CT findings of orbital pseudotumor and to define differentialpoints from other pathology, the authors retrospectively reviewed CT of 19 patients who were prooen to have orbital pseudotumor by clinical course and, in some cases, biopsy. A variety of CT findings including extraocular muscle thickening(11 cases), streaky infiltration of retroorbital fat(11 cases), mass formation(10 cases), optic nerve thickening (6 cases), conjunctival thickening (5 cases), scleral thickening(4cases), enlarged lacrimal gland(4 cases) and destruction of orbital bone (2 cases) were observed. Thickening of the anterior portion and irregular margin were characteristic findings of extraocular muscle and optic nerve lesions. Mass formation predominantly occurs in the anterior portion of the orbit. In most cases more than two orbital structures are involved by lesion.

Simulated three-dimensional (3D) imaging represents reformation of conventional sectional imaging data into a series of images that closely resemble the original studied structure. We tried to make 3D mucosal surface images of the sinonasal cavities, pharynx and larynx, and evaluated the feature of normal anatomy in 28 subjects. In the sinonasal cavities, 3D imaging was capable of demonstrating the inner wall of paranasal sinuses and its openings, and general status status of the nasal cavity. In the nasal cavity. In the nasopharynx, 3D imaging provided an easy concept of sectional images as 3D picture and displayed anatomic subsites and lesions comparable to that in fiberscope. In addition, 3D imaging had advantages in overcoming the technical limitations in fiberscope. In the larynx and hypopharynx, 3D imaging gave a 3D concept of the laryngeal structures and presented additive information not seen in axial iamges thus enabling access to regions beyond the scope of fiberscope. In conclusion, 3D imaging allows an easy conceptualization of transaxial CT images in complex anatomic areas and provides additional in formations undetectable in transaxial CT. We believe that the spaces of the sinonasal cavities, pharynx and larynx would be a new field of application of 3D image.

Subclavian steal syndrome caused by an acute thrombus is very rare. We present a case of cerebellar infarction with proximal subclavian artery thrombosis. A 56-year-old woman was admitted for sudden vertigo. One day prior to admission, she received a shoulder massage comprised of chiropractic manipulation. On examination, her left hand was pale and radial pulses were absent. Blood pressure was weak in the left arm. Downbeat nystagmus and a right falling tendency were observed. Brain MRI showed multiple acute infarctions in the left cerebellum. The findings of Doppler ultrasonography in the left vertebral artery were compatible with a partial subclavian artery steal phenomenon. Digital subtraction angiography demonstrated a large thrombus in the left subclavian artery. After heparin infusion, thrombus size markedly decreased. Cerebellar infarction caused by acute subclavian thrombosis following minor trauma is rare, but the thrombus can be successfully resolved with anticoagulation.

Aprotinin, a proteinase inhibitor, is known to significantly reduce blood loss during cardiac, thoracic and vascular surgery. Despite the wide use of this medication, there are only a few reports of anaphylactic reactions. We experienced a case of severe intraoperative anaphylactic reaction due to reexposure of aprotinin used to reduce intraoperative bleeding. During anesthesia for brain tumor removal, systemic hypotension and generalized rash were developed following the administration of aprotinin in a 34-year-old woman. We suggest that it is necessary, in patients known to have had previous aprotinin therapy, to perform skin test with diluted aprotinin before infusion.

An inflammation of an epiploic appendage is a relatively rare cause of acute abdominal pain. It can be clinically misdiagnosed as either acute appendicitis or diverticulitis. Judicious interpretation of imaging with ultrasound or computed tomography may lead to an early diagnosis and prevent unnecessary surgical or medical treatment. Conservative treatment of symptoms is usually sufficient. We have experienced a case of epiploic appendagitis treated by conservative management and report this case with the review of the literature.

In patients with acute ischemic stroke, early treatment with thrombolytic agents is thought to permit reperfusion to ischemic but still viable brain areas and to promote recovery of function. However, reocclusion and hemorrhagic transformation may occur after thrombolysis and these are major factors of no-improvement or deterioration despite the initial successful recanalization. Reocclusion occurs frequently during or immediately after successful recanalization, often silently. In the case of reocclusion, initial platelet-fibrin thrombi are converted into platelet-rich thrombi by platelet-mediated thrombotic mechanisms. Therefore, if can be effectively resolved by use of the platelet membrane glycoprotein IIb/IIIa receptor inhibitors such as abciximab. Hemorrhagic transformation (HT) is a well-known factor limiting the use of thrombolytics and negating the effect of the treatment. Recent studies demonstrate that loss of integrity of the blood-brain barrier in association with active proteolytic degradation of vascular extracellular matrix is a key molecular pathway leading to HT. Therapeutic strategies to prevent reocclusion and HT by use of agents that act against these mechanisms before or during thrombolysis are warranted to enhance the efficacy of reperfusion therapy in stroke.

Tracheobronchopathia osteochondroplastica (TO) is a rare idiopathic tracheobronchial abnormality characterized by diffuse cartilaginous and osseous nodules protruding into the airway lumen of the trachea and bronchus. TO is easy to misdiagnose because of nonspecific symptoms and chest CT scan with pathologic biopsy is necessary for definitive diagnosis. We report two cases of patient with TO who underwent laryngomicroscopic biopsy and tracheostomy with literature review.
