We report a case of acute intermittent porphyria presenting with variable symptoms and signs such as hypertension, polyneuropathy, syndrome of inappropriate secretion of antidiuretic hormone and cerebral infarction. A 47 year-old female patient entered hospital with abdominal pain followed by generalized seizure. She was diagnosed to have acute intermittent porphyria in consequence of Watson-Schwartz test and δ-ALA in 24 hours urine. She was managed with conservative treatment but died of respiratory failure.

Three cases of Dupuytrens contracture which developed in hands were reported along with review of literatures. Partial fasciectomy was done as the choice of treatment for them to improve impairment of function of the hands. No attributable causes for the developement of the disease were found.

The MR images of 13 patients with brain abscesses were retrospectively reviewed. The abscesses were solitary in 11 patients and multiple in 2 patients. They were located in the corticomedullary junction of the cerebral hemispheres(11) and cerebellum (2).: The sizes of the abscesses were variable, ranging from 1 cm to 5 cm in diameter. They were round (5), oblong (4) or multilobulated (4) in shape. Massive surrounding edema was found in 12 patients. The signal intensity of the abscess contents was hypointense to gray matter and hyperintense to CSF on T1-weighted images, and hyperintense to gray matter on both proton-density-and T2-weighted images. In 5 patients the abscess contents were heterogeneous on both T1-and T2-weighted images. The signal intensity of the abscess walls was isointense(11), slightly hyperintense (1) or hypointense (1) relative to gray matter on T1-weighted images, whereas they were isointense (4) or hypointense (9) on T2-weighted images. Of 10 patients with Gd-enhanced-T1-weighted images, 5 patients(50%) showed thin, smooth, rim enhancement, while the other 5 patients revealed somewhat irregular thick wall enhancement Satellite or daughter abscesses were found in 6 patients. Meningeal or ventricular wall enhancement suggesting meningitis or ventriculitis was associated in 3 and 1 patient, respectively. In conclusion, the characteristic morphology and intensity of the abscess capsule, massive surrounding edema, satellite abscess and associated meningitis or ventriculitis are characteristics of the brain abscess, even though they are not entirely specific to allow for accurate diagnosis in all patients.

PURPOSE: Authors reviewed CT and MR findings of patients with parapharyngeal masses, and their incidence and characteristic findings were studied. MATERIALS AND METHODS: We reviewed 27 CT and 9 MR of pathologically proven 29 patients with primary parapharyngeal mass Neurogenic tumor (17 cases) and other rare masses (3 carotid body tumors, 2 pleomorphic adenomas, 2 cavernous hemangiomas, 1 cavernous lymphangioma, 2 carotid artery pseudoaneurysms, 1 non-Hodgkin's lymphoma, 1 idiopathic cervical fibrosis) were included and the characteristic CT and MR findings were studied. RESULTS: Neurilemmoma was seen as a well-demarcated, solid mass of heterogeneous attenuation or intensity, so that pleomorphic adenoma of minor salivary gland origin could not be differentiated by demarcation, attenuation, or signal intensity of the tumor itself. The direction of carotid artery displacement was not constant in cases of neurilemmomas while the styloid process was constantly displaced laterally in all cases. Characteristic CT and MR findings of other rare tumors were described. CONCLUSION: Neurogenic tumor is the most common parapharyngeal space mass and the direction of displacement of styloid process might be helpful in differential diagnosis from pleomorphic adenoma. Other rare tumors showed very characteristic CT and MR finidings and could be differentiated easily.

We retrospectively analyzed the Magnetic Resonance (MR) imaging findings in 41 cases of histologically proved malignant tumors of oral cariey. The diagnostic value of MR imaging in detection and delineation of the lesions was assessed. The value of MRI was compared with that of Computed Tomography (CT) in 14 patients. Thirty-four cases of 41 malignant tumors were squamous cell carcinomas. Adenoic cystic carcinomas (2 cases), malignant melanomas (2 cases), non-Hodgkin lymphomas (2 cases) and mucoepidermoid carcinoma(1 cases) were also included in this study. Most of the lesions were isointense or slightly hyperintense to muscle on T1 weighted images and showed variable degrees of high signal intensity on T2 weighted images. Two cases of malignant melanomas showed characteristic hyperintensity on T1 weighted images. T2 weighted image was better in detection and delineation of tumor in most of the cases. In 6 cases, Gd-DTPA-enhanced T1 weighted image was better than T2 weighted image. T2 weighted image was useful for the evaluation of deep tissue infiltration and T1 weighted image was useful for the evaluation of bone invasion and superficial tissue plane invasion. The lesion was detected only by MR in 3 cases of 14 in which CT was also performed. MR imaging was more sensitive in the evalustion of bone marrow involvement. MR imaging is very useful modality in evaluating oral cavity malignany and is superior to CT in delineation of the as well as in the evaluation of mandible invasion.
