Rupture of anterior communicating artery aneurysm is one of the most important casuses of subarachnoid hemorrhage. Subarachnoid hemorrhage due to ruptured anterior communicating artery aneurysm shows characteristic CT findings, such as forntal hematoma or septum pellucidum hematoma. In some patients with the ruptured aneurysm, direct carotid angiography may be needed. particularly when transfemoral approach is not possible. However, not much have been known about the puncture site selection between the two carotid arteries in relation to the location of hematoma in CT scans. To determine the ideal puncture site of the direct carotid angiography, seventy-five cases of anterior communicating artery aneurysm confirmed by operation from May 1988 to April 1992, were analyzed in terms of relationship between location of hematoma on CT, direction of aneurysm and A1 artery on angiograms. Frontal lobar hematoma was more prevalent than septal hematoma, and was more common on the right side. In cases of lobar hematoma, aneurysm was directed to the ipsilateral side of the hematoma (67%) and was most commonly fed by contralateral A1 artery(75%). Septal bematoma consisted 36% of the cases and among there, midline directed aneurysm was most common, frequently fed by left A1 artery. In conclusion, when performing direct carotid angiography in patients with anterior communicating artery aneurysm, if forntal hematoma is observed on CT, it may be beneficial to puncture contralateral carotid artery. Meanwhile, if hemorrhage of septum pellucidum is observed, it may be better to puncture left carotid artery.

Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.

Histiocytosis X(Langerhans cell histiocytosis) is a rare prolifertive disorder of Langerhans cells that includes Lettere-Siwe disease, Hand-Shiiller-Christian his ase and eosinophilic granuloma. Since many authors have reported in anintermediate and poarl classified form histiocytosis X has a namenclatural had nosologic problem. We report a case benign cutaneous variant of histiocytisis X. A four-month-old boy had shown multiple skin-colour papules on the trunk, head and nik for one month. Extensive in- vestigations failed to detcct any systemic involvement. The clixron microscopic findings of the skin biopsy specimen were Qefinitely diagnostic for histiocytosi. X Since he did not sbow evidence of internal organ involvernent and any further progression of he skin lesion, no therapy was given. Over the next two months the disease underwent spontane us and complete remission.

We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.

Therapeutic irradiation can induce angiosarcoma. Radiation-induced angiosarcoma constitutes 20% of all angiosarcomas. Although its common site of origin is the skin and subcutaneous tissue, it rarely arises in small or large bowels with a presentation as multifocal abdominal angiosarcomatosis. We report a case of intra-abdominal angiosarcomatosis involving the jejunum, ileum, transverse colon, mesentery and right ovary in a 63-year-old female. It developed 10 years after therapeutic irradiation for squamous cell carcinoma of uterine cervix. She developed panperitonitis due to intestinal perforation. She died from sepsis 3 days after segmental resection of the small bowel and right oophorectomy. We reviewed the previously reported cases and describe the clinicopathologic features of this tumor.

Failure of automatic control of ventilation (Ondine's curse syndrome) is a rare syndrome that sometimes occurs following localized brainstem dysfunction. In this report, we present a case of a 52-year-old male who was admitted to the hospital with sudden-onset nausea. On examination, no lateralization signs were presented. After one hour, his consciousness was altered and he became apneic. After endotracheal intubation and mechanical ventilation, his mentality improved and he was able to ventilate spontaneously. Cranial magnetic resonance imaging demonstrated acute infarction in both cerebellar inferior aspects involving the right side of the medulla. Eleven hours later, the patient's consciousness altered again. Computed tomography demonstrated newly developed hydrocephalus and emergent craniotomy, and extraventricular drainage were performed. The patient improved in both consciousness and respiratory status but complained of mild ataxia and left arm weakness. We recommend cautious examination and early diagnosis and therapeutic decisions in cases of patients with atypical presentation of stroke.

PURPOSE: To evaluate the feasibility of in-vivo 1H magnetic resonance spectroscopy (1H-MRS) for differentiation between hepatic and renal cysts, with emphasis on the analysis of cystic content. MATERIALS AND METHODS: The 1H-MR spectra of 43 cystic lesions (15 hepatic and 28 renal) obtained using in -vivo 1H-MRS at 1.5 T and with a localized proton STEAM sequence were evaluated. We calculated the ratio of the peak area of lipid/water (Rlipid/water), protein/water (Rprotein/water) and lipid/protein (Rlipid/protein), paying particular attention to identifying differences in peak area ratios between the two types of cyst. RESULTS: The 1H-MR spectra from 26.7% (4/15) of hepatic and 67.9% (19/28) of renal cysts showed the lipid peak as most prominent. Mean+/-standard deviations of the Rlipid/water of hepatic and renal cysts were 0.38+/-0.30x10-6 and 8.42+/-23.24x10-6, respectively; for Rprotein/water the corresponding figures were 0.83+/-0.74x10-6 and 1.50+/-2.94x10-6, and for Rlipid/protein, 0.57+/-0.64 and 2.44+/-3.26. All differences were statistically significant (p<0.05), and positive correlation between lipid and protein in hepatic and renal cysts was demonstrated. CONCLUSION: The different in-vivo 1H-MRS findings, for hepatic and renal cysts can be used in comparative study of cystic tumors of the liver and kidney.
