Teratoma is very rarely developed in the third ventricle. We report a case of third ventricular mature teraroma in 12 year old boy with headache and precocious puberty. In TlWl and Gd-DTPA enhanced TlWl, the mass in the third ventricle showed mixed signal intensities with signal void and partial contrast enhancement. The tumor was confirmed as a mature teratoma including teeth and fatty tissue.

Measurement of the normal pituitary gland height was performed on magnetic resonance (MR) images of 144 subjects with no known or suspected pituitary or hypothalamic diseases. Midsagittal T1 weighted images (T1WI) were used for measurement, and mean vertical height according to age and sex group was obtained. In all age groups, the pituitary height was greater in females than in meles, The group of 0-9 years in both genders showed the minimum mean pituitary height, The maximum mean height was observed in the 10-19 years age group in both genders. The height gradually decreased with increasing age after age 20 years. There was no subject with a height more than 9.0 mm in females or 8.0 mm in males. In conclusion the measurement of the normal pituitary pland height using mid sagittal MR imaging can be used for the evaluation of the pituitary gland lesions.

Rieger's syndrome is a rare autosomal dominant developmental anomaly characterized by ocular and systemic abnomalities. These disorders are typically bilateral and usually diagnosed at birth or in the childhood. The most common ocular defects are hypoplasia of the iris, a prominent Schwalbe's line with iris strands and corectopia. A large number of patients have glaucoma due to devel-opmental defects of the anterior chamber angle structure. The authors experienced a case of Rieger's syndrome which was found in 31-year-old female, who had characteristic ocular and other systemic abnormalities. Associated glaucoma was well controlled by filtering surgery.

Diabetes mellitus, obstructive uropathy and urinary infection were considered to be most important in the etiology of renal papillary necrosis in the past literature. However, since 1953, Spuhler and Zollinger reported an association between phenacetin abuse and renal papillary necrosis, the most frequent cause of renal papillary necrosis has been diabetes mellitus, while analgesic abuse (contained phenacetin) has been the second most common factor in recent reports. In the more recent literature, most of the patient have had neither obstructive uropathy nor urinary infection, and it is quite possible that there two condition are of no direct etiological significance. But in this case, we can not suggest definite etiological factor except urinary infection clinically. Only one case is reported showing clinical manifestations laboratory findings, pyelographic findings and pathological changes compare with previous papers.

Cervical tuberculous lymphadenitis is a commonly encountered disease, expecially in adults, Differentiation from other lymphadenopathy and benign conditions such as cystic neck masses is important. CT findings of tuberculous lymphadenopathy in the abdomen and thorax are reported in many literatures. But there are only a few articles concerning cervical tuberculous lymphadenopathy. The authors retrospectively analyzed CT findings of 33 cases with cervical tuberculous lymphadenitis regarding distribution, contour, enhancing pattern, changes of adjacent fascial plane, and dermal and subcutaneous manifestations. We concluded that the presence of conglomerated nodal masses with central lucency, thick irregular rim of contrast enhancement and inner nodularity, varying degree of homogenous enhancement in smaller nodes, dermal and subcutaneous manifestations of inflammation such as thickening of overlying skin, engorgement of the lymphatic and thickening of adjacent muscles, and diffusely effaced fascial plane are suggestive of tuberculous lymphadenitis. However, some CT patterns of tuberculous adenitis may be seen in other disease; for example, enhancement can occur in hyperplastic nodes, vascular metastasis(thyroid, melanoma, and hypernephroma), lymphoma, granulomatous disease, and Castleman's disease.

OBJECTIVES: Contemporary empirical studies have suggested high rates of comorbid attention-deficit hyperactivity disorder(ADHD) or obsessive compulsive disorder(OCD) in children with tic disorders. Not infrequently, ADHD or OCD is as source of greater impairment than are the tic symptoms. The studies in the pathophysiology of tic disorder have implicated abnormalities of dopamine, serotonin and norepinephrine. The studies in pathophysiology of ADHD or OCD also have implicated abnormalities of dopamine, serotonin and norepinephrine. This study was purposed to examine the differences in tic severities and in the levels of plasma homovanillic acid(HVA) and 5-hydroxyin-doleacetic acid(5-HIAA) according to the presence of comorbid ADHD or OCD in patients with chronic tic disorders. METHODS: In fifty chronic tic patients, OCD or ADHD was also diagnosed. And then tic symptoms, obsessive-compulsive symptoms, and attention-deficit hyperactive symptoms were assessed using Yale global tic severity scale(YGTSS), Leyton obsessional inventory-child version(LOI-CV), and Conners parent rating scale. The plasma HVA and 5-HIAA levels were measured using high performance liquid chromatography with electrochemical detection method. RESULTS: Fifty-eight percent of the patients with chronic tic disorders had comorbid ADHD or OCD. But severities of tic did not differ regardless of the presence of comorbid ADHD or OCD. There was a significant positive correlation between tic severities and plasma HVA levels but none between tic severities and plasma 5-HIAA levels. There was a significant inverse correlation between resistance and interference scores and plasma 5-HIAA levels. Plasma HVA levels showed significant positive correlations with plasma 5-HIAA levels. CONCLUSION: These results showed that tic severities didn't vary according to the presence of comorbidities, and that tic severities were correlated with plasma HVA levels, not with plasma 5-HIAA levels. These results suggested that the pathophysiology of chronic tic disorder was strongly correlated with abnormalities of dopaminergic system.
