Fetal abnormalities in central nervous system are now recognized more often with the increasing use of high-resolution prenatal sonography. Arachnoid cysts, because of their compression of adjacent brain tissue, may require neurosurgical intervention but otherwise they have a good long- term prognosis. The differential diagnosis of intracranial lesions is important to allow accurate counselling and also to optimize neonatal management. We report the two cases of fetal arachnoid cyst diagnosed with prenatal ultrasonography

We report the sonographic features of an intracystic papillary carcinoma of the breast presenting as recurrent hemorrhagic cysts following trauma. A 56-year-old woman presented with palpable breast masses after a traumatic event; sonography showed multiple, well-defined, hemorrhagic cysts. Hemorrhagic fluid was evacuated by fine needle aspiration with no residual lesions. Cytology was negative for malignancy. Five months later, the mass reappeared; sonography demonstrated multiple cysts with solid nodules. US-guided core biopsy and surgery revealed invasive papillary carcinoma. We suggest close follow-up of cystic masses, even with negative cytology, and performance of surgical excisional biopsy in cases of rapid refilling after aspiration.

With the development of fetal ultrasonography, detection of fetal ovarian cysts has been increased. Although ovarian cyst formation during the perinatal period is a self limiting process, there is still considerable controversy regarding the best treatment of the fetal ovarian cyst. The purpose of this study is to evaluate the natural history of fetal ovarian cysts and to analyze the result of treatment. From 1995 to 2004, 31 consecutive fetuses with ovarian cysts were followed by ultrasonography during the perinatal period. The fetal ovarian cyst was diagnosed by prenatal ultrasonography between 25weeks and 38 weeks and the mean size of the cysts was 5cm (ranged from 2 to 8cm). At birth, 3 cysts disappeared. In 2 cases, the diagnoses were changed to multicystic kidney disease and intestinal duplication. During following up of 26 cysts, 15 cysts have resolved completely. Seven cysts required oophorectomy because of cyst torsion (n=3), differentiation of tumorous condition (n=2), increased size of cyst (n=1), and large size (8cm) of cyst at birth (n=1). Fetal ovarian cyst should primarily be observed, and only in the limited cases, surgical treatment would be required for the risk of complications such as torsion and differentiation from benign to malignant pathology.

Arachnoid cysts represent 1 percent of all intracranial masses. Their common locations include the middle cranial fossa, the quadrigeminal cistern, the suprasellar region, the posterior fossa, and the region of the cerebral convexities. Midline cysts often create a disturbance in intracranial dynamics due to the shift and displacement of surrounding structures, and then developed hydrocephalus. So, early diagnosis and treatment of these cysts are important. The arachnoid cyst by ultrasonogram shows characteristic well capsulated homogeneous hypoechoic cyst. We report a case of prenatally diagnosed suprasellar arachnoid cyst by ultrasonogram and MRI, which was treated postnatally.

PURPOSE:The purpose of this study is to evaluate the ultrasonographic finding and clinical course of fetal ovarian cysts. METHODS:A retrospective study of 11 cases of fetal ovarian cysts, evaluated by prenatal and postnatal ultrasonographic studies was conducted. We analyzed the demographic factors, the ultrasonographic findings, the change of ultrasonographic parameters, the mode of delivery, the management of ovarian cysts and pathologic finding. RESULTS:In all cases, fetal ovarian cysts were unilateral simple cysts at the time of diagnosis. The mean sizes of the ovarian cysts were 29.7 mm on prenatal and 19.8 mm on postnatal studies. In four of the 11 cases, the ultrasonographic patterns of cysts changed from simple to complicated cysts on serial monitorng, and one of them required postnatal surgery. Ten of 11 cases were spontaneously resolved during perinatal follow-up ultrasound. CONCLUSION:We recommend continuous ultrasonographic assessment of antenatally diagnosed ovarian cysts, which is helpful to predict the outcome of cysts and decide on the management.

Splenic cysts are unusual in daily surgical practice and less than 1000 cases have been reported. Primary, true or epithelial splenic cysts, are even rarer. Usually, most of the cysts are asymptomatic until of significant size, at which time they are then detected incidentally on ultrasonography or CT scan. We report a case of a 25-year-old woman with giant epithelial splenic cyst with about 3000 ml of clear-yellow fluid was collected from the cyst. The splenectomy specimen measured 205 mm × 192 mm × 137 mm and weighed 4000 g.

BACKGROUND: The purpose of this study was to report the ultrasonographic findings and clinical features of schwannoma of the hand. METHODS: We enrolled 8 patients who were initially diagnosed with ganglion by ultrasonography but finally with schwannoma by a tissue biopsy. We retrospectively analyzed the ultrasonographic findings of eight patients including echogenicity, internal homogeneity, posterior enhancement, internal vascularity, and clinical manifestations such as the occurrence site, tenderness, Tinel's sign, and paresthesia before the surgery. RESULTS: The occurrence sites were as follows: two cases on the thenar area, one case on the second web space, three cases on the third web space, one case on the radiovolar aspect of the proximal phalanx of the index finger, and one case on the radiovolar aspect of the proximal phalanx of the middle finger. Four patients suffered from tenderness and pain on presentation, and all patients had pain around the mass before presentation. Tinel's sign was present without paresthesia in one case. Ultrasonography revealed cystic lesions showing clear margins in all cases, and two of them had acoustic enhancement without internal flow. CONCLUSIONS: It may not be easy to diagnosis schwannoma of the hand with ultrasonography alone when the lesion is small because of the similarity to the ultrasonographic findings of ganglion. Therefore, it is necessary to consider the possibility of schwannoma if a mass near the digital nerve or cutaneous nerve branch is accompanied by dull pain and tenderness.

We report a case of hyperreactio luteinalis in a patient with normal singleton pregna-ncy. In the 10th week of gestation, the patient developed lower abdominal pain accompanied by abdominal distension. Ultrasonography revealed bilateral ovarian cysts. Right salpingo-oophorectomy was performed due to torsion of right ovarian cyst. The pathologic diagnosis was corpus luteal cyst. Any signs of maternal virilization were not seen. The patient deliv-ered a normal male infant at 39th week of gestation. As hyperreactio luteinalis is a benign condition in itself with normal spontaneous remission after delivery, the conservative man-agement may be appropriate.

Sixteen cases of intracranial arachnoid cyst were diagnosed with computerized tomography(CT). Four patients also had subdural hematoma, two of them following head trauma. Arachnoid cysts in Sylvian fissure are divided into three types, according to their shape and extension on CT. Male was predominant in sex distribution and Sylvian fissure was prevalent in location. Seizure and focal thinning of bone were the most frequently encountered clinical and radiological findings. Surgical procedure was performed in nine cases with partial excision of the cyst membrane or cystoperitoneal shunt. The authors discussed the pathogenesis, clinical findings and treatment of the intracranial arachnoid cyst. We support the congenital origin as pathogenesis, with the experience of one case, which was diagnosed before delivery with ultrasonogram. Considering the potential morbidity of the cyst, as subdural hematoma formation, we propose the surgical treatment as soon as the diagnosis is made.

OBJECTIVE: The aim of this study is to review 4 years' experience of peritoneal inclusion cysts at Kangnam St. Mary's Hospital. METHODS: A retrospective study of 50 cases of peritoneal inclusion cyst between April 1, 1999 and June 30, 2003 was carried out and then clinical feature, preoperative diagnostic findings, operative findings and recurrence were compared with previous reports. RESULTS: The mean age of patients was 40.2 years old and most of them were premenopausal. The majority (94%) of patients had history of laparotomy and most (70.2%) of them had history of total hysterectomy. The values of tumor makers such as CA125 and CA19-9 were normal in most of the patients. The peritoneal inclusion cysts usually generate on the left side of the pelvic cavity, size of them were often (59.6%) 5 to 10 cm and they usually (65.4%) have septum in ultrasonographic findings. They probably had pelvic adhesion or ovarian cyst with them in operative findings. Most of the recurrence occurred after only adhesiolysis was done. CONCLUSION: Because peritoneal inclusion cyst is benign and uncommon disease, its preoperative diagnosis rate was low. In our experience of 50 cases of peritoneal inclusion cyst, most of the patients have history of laparotomy and were premenopausal. When the ultrasonographic findings of cyst are 5 cm to 10 cm in size and have septum, they are likely to be peritoneal inclusion cyst. Their recurrence might be more common when adhesiolysis only was performed.
