Localized fibrous mesothelioma of the liver is very rare benign tumor. It usually manifest large palpable hepatic mass in right upper quadrant area, and the prognosis is excellent by surgical resection. Contrast enhanced CT scan shows well defined hyperattenuating mass and celiac anglogram shows hypervascular mass. Recently we experienced 1 case of localized fibrous mesothelioma of the liver, and we report CT and anglographic findings of this tumor.

BACKGROUND AND OBJECTIVES:Traditionally, down beat nystagmus is regarded as a sign of central nervous system dysfunction. But, several years has passed since Herdman et al reported the down beat nystagmus developed during treatment maneuvers for posterior semicircular canal benign paroxysmal positional vertigo(BPPV). We undertook this study to evaluate the character and clinical analysis of the positional or positioning down beat nystagmus, to discuss the clinical significance of positional or positioning down beat nystagmus as a diagnostic criteria of superior semicircular canal BPPV, and to propose the new treatment method. MATERIALS AND METHOD:From November 1999 to March 2004, we sampled the 103 patients with positional or positioning down beat nystagmus. Of these patients, we selected 16 patients except for the patients with central nervous system dysfunction, nonspecific or artifact result, idiopathic origin. RESULTS:All of 16 patients had no sign and radiologic result of central nervous system disorder. 10 patients was reported or suspected the diagnosis of posterior semicircular canal BPPV. Fatigability was reported in 9 patients and reversibility was reported in 1 patient. Average latency was checked less than 2 seconds. CONCLUSION:Although the diagnostic criteria of superior semicircular canal BPPV that we reported was not controversial, we expect that this criteria is useful in diagnosis for patients with atypical positional or positioning down beat nystagmus. And the new treatment method that we reported will has the better results than previous method.

Massive ovarian deema is a tate conditian. It is a benign enlargement of the ovary caused by accumulation of fluid, which is thought to result from intermittent partial toraion of the ovarian pedicle. Histologically, the ovaries were characterized by diffuse edema of medulla and inner cortex. Two cases of massive ovanan edema are reported with brief review of the literatures.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.
