1/133. Adrenal endothelial cyst with massive central calcification.

    A 55-year-old woman was treated for a rare case of adrenal endothelial cyst that was detected incidentally during management of abdominal pain. Computed tomography of the tumor displayed massive central calcification and a fluid-fluid level by intracystic hemorrhage. magnetic resonance imaging showed an intracystic papillary part with calcification. After surgery, the tumor was diagnosed as an angiomatous type of adrenal endothelial cyst.

2/133. A case of small cerebral cyst and pericentric inversion of chromosome 9 that developed schizophrenia-like psychosis.

    A case of schizophrenia-like psychosis (psychotic disorder not otherwise specified according to the DSM-IV criteria) with pericentric inversion on chromosome 9 [inv.(9) (p11; q13)] is reported. In this case, a minor brain anomaly, a small cyst in the left subcortex, was observed on magnetic resonance imaging of the brain. In the clinical course, prominent chronic hallucinations were observed; however, there was no evidence of the disorganization of personality, delusion, and deterioration in level of functioning that are usually seen in schizophrenia. This case and a review of the literature indicate that the pericentric region of chromosome 9 might be a potential areas of interest for the aetiology of psychiatric disorders. The phenotype-karyotype relationship of pericentric inversion on chromosome 9 and its relationship to psychosis are discussed.

3/133. Hemorrhagic adrenal cyst: an unusual reason of acute hypovolemia.

    Adrenal cysts are often asymptomatic and included in the larger "incidentaloma" group. They may reach significant size without onset of compressive symptoms and are often left undiagnosed until an ultrasound or CT scan are performed for a vague lumbar or flank discomfort. Intracystic hemorrhage is a rare but life-threatening complication since a sudden and significant blood loss may occur without any evident clinical source, hypovolemic shock resulting as the first symptom. The authors report their personal experience in two patients along with a review of the literature on this insidious emergency, its diagnosis and therapeutic approach.

4/133. Vascular adrenal pseudocyst: cytologic and immunohistochemical study.

    Adrenal vascular cysts are rare lesions that might be considered in the differential diagnosis of adrenal tumors. Their origin is not clear. We report the clinicopathological findings of a large adrenal hemorrhagic pseudocyst (AHP) in a 73-yr-old man who complained of abdominal pain. An abdominal CT showed a 9 cm tumor in the left adrenal. A fine-needle aspiration biopsy (FNAB) was hemorrhagic and inconclusive. The tumor was excised and touch imprints were taken showing groups of spindled and fusiform cells with elongated nuclei, without atypia. Histologically, the tumor was well delimited by a fibrous capsule and contained numerous cystic spaces lined by endothelial cells and filled with erythrocytes, fibrin thrombus, and necrotic debris. Immunohistochemical study showed strong positivity for factor viii-RA, CD31, and CD34. Also, the remaining adrenal showed a prominent frame of thin and medium caliber vessels, supporting a vascular origin for this entity. This case illustrates the difficulty in making a diagnosis by FNA and to keep in mind AHP when hematic aspirates are obtained from an adrenal tumor mass.

5/133. Haemorrhage into non-functioning adrenal cysts--report of two cases and review of the literature.

    Adrenal cysts are a rare condition and are usually non-functioning and asymptomatic. Most of the reported cases were incidental findings or discovered at autopsy. However, large cysts have a tendency to develop complications such as intracystic haemorrhage and rupture, which can present as an acute surgical emergency. We report two cases of adrenal cysts with intracystic haemorrhage. One patient presented with persistent non-specific upper abdominal pain, investigations with ultrasound (US) scan and computed tomographic (CT) scan revealed a left adrenal cyst and gallstones. Simultaneous cholecystectomy and adrenalectomy was performed with resultant relief of symptoms. The second patient presented with acute abdominal pain simulating acute surgical abdomen. Preoperative CT scan showed a large cystic lesion in the region of the tail of the pancreas with radiological evidence of haemorrhage but was unable to confirm its origin. The cyst was found to have arisen from the left adrenal gland at laparotomy; left adrenalectomy with complete excision of the cyst was done. histology showed pseudocyst with haemorrhage in both cases. Pseudocyst is the commonest histological type encountered clinically. We believe the second case is related to pregnancy and childbirth as the patient presented during puerperium and the cyst, even though very large in size (25 x 15 x 15 cm), was not noted during antenatal screening with US scan.

6/133. Isolated visceral leishmaniasis presenting as an adrenal cystic mass.

    A 69-year-old woman presented with a large left retroperitoneal suprarenal mass. Radical resection of the left kidney and the mass revealed a cystic adrenal tumor with a weight of 1500 g. Histologic examination showed that the cyst was composed mostly of partially organized clotted blood. The periphery of the mass consisted of a thin rim of cortical and medullary adrenal tissue with superimposed granulomatous chronic inflammation. The infectious nature of the process was manifested by the scattered intracellular and extracellular Leishmania amastigotes that were found throughout the lesion. The differential diagnosis of cystic adrenal masses and the unusual presentation of visceral leishmaniasis are discussed in this context.

7/133. Foveal pseudocyst as the first step in macular hole formation: a prospective study by optical coherence tomography.

    OBJECTIVE: To establish the natural history of a series of impending macular holes presenting as foveal pseudocysts using optical coherence tomography (OCT). DESIGN: In a prospective observational case series, patients exhibiting a foveal pseudocyst on biomicroscopy were examined with OCT and were followed up for 3 to 26 months (mean, 9.4 months) PARTICIPANTS: Twenty-two eyes of 20 consecutive patients examined for a macular hole in the fellow eye or reporting visual symptoms in only one eye, in whom a foveal pseudocyst was diagnosed on OCT. methods: In all cases, fundus biomicroscopy and OCT findings were compared. MAIN OUTCOME MEASURES: Biomicroscopic fundoscopy, OCT scans, and visual acuity. RESULTS: Eight foveal pseudocysts occurred in the fellow eye of an eye with a macular hole, and 14 were diagnosed in patients with unilateral visual symptoms. In four of the 22 eyes, the macula was considered normal on biomicroscopy. In the 18 others, biomicroscopy detected a foveal pseudocyst, radial striae, a yellow spot or ring, or a combination of these findings. No posterior vitreous detachment was seen on biomicroscopy in any of the eyes. On OCT, the cystoid space occupied the inner part of the foveal tissue in the stage 1A impending hole; a stage 1B impending hole corresponded to a cystoid space that extended posteriorly, disrupting the outer retinal layer. During the follow-up period, three pseudocysts evolved into full-thickness macular holes, four turned into lamellar holes, seven resolved completely after detachment of the posterior hyaloid, and eight remained unchanged for a long time. CONCLUSIONS: Foveal pseudocysts are a specific entity occurring either as a primary ocular involvement or in the fellow eye of an eye with a macular hole. Foveal pseudocysts are the first step of full thickness macular hole formation, but they also may evolve into a lamellar hole, may persist unchanged for months, or may resolve completely. Foveal pseudocyst formation may be the result of the incomplete separation of the vitreous cortex at the foveal center and the particular structure of the foveal Muller cells.

8/133. Adrenal cyst--a case report.

    Adrenal cysts are rare and mostly silent clinically. Herein we report a case of adrenal cyst. A 55-year-old female was incidentally found to have a left suprarenal cystic lesion with a calcified wall by abdominal sonography during a work-up for her epigastralgia and left flank pain. Then, computed tomography (CT) revealed a left adrenal cystic mass with wall calcification, magnetic resonance imaging (MRI) showed left retroperitoneal cystic mass with fluid content, and angiography demonstrated an avascular lesion. Surgical exploration was performed via a flank incision and a calcified cystic adrenal mass was excised. The pathologic diagnosis was adrenal pseudocyst with calcified wall. We discuss the diagnosis and management of adrenal cyst and briefly review the literature.

9/133. Hepatocyte nuclear factor-1beta: a new kindred with renal cysts and diabetes and gene expression in normal human development.

    The hepatocyte nuclear factor-1beta (HNF-1beta) transcription factor controls endoderm development. Human mutations cause early-onset diabetes mellitus and have recently been associated with dysplastic, hypoplastic, and glomerulocystic kidneys. A new kindred with this "renal cysts and diabetes" syndrome is described, and nephrogenic HNF-1beta expression is defined. The proband had congenital cystic kidneys: over the next 12 yr, his renal function was impaired, but he was normoglycemic. His mother developed diabetes during pregnancy: renal ultrasonography at age 24 yr was normal, but she subsequently developed cysts. Both subjects have a heterozygous frameshift mutation in HNF-1beta that results from a 1-bp insertion in exon 5 (Y352fsinsA). When reverse-transcription PCR and in situ hybridization were used, HNF-1beta mRNA was detected in normal human metanephroi, with the highest levels of transcripts localized to fetal medullary and cortical collecting ducts and low levels of expression in nephrogenic cortex mesenchyme, primitive nephron tubules, and immature glomeruli. These results constitute the first demonstration of HNF-1beta expression during human nephrogenesis and emphasize a disease spectrum associated with HNF-1beta mutation.

10/133. Adrenal cyst: a review of the Japanese literature and report of a case.

    Adrenal cysts are a rare condition and are usually non-functioning and asymptomatic. A 44-year-old man was referred from another hospital because a left retroperitoneal tumor was incidentally found by abdominal echography. Laboratory findings including adrenal hormonal study were within the normal range. It showed homogeneously low intensity on T1-weighted images and high intensity on T2-weighted images on magnetic resonance imaging (MRI). angiography demonstrated that the tumor was avascular and of left adrenal origin. The patient was diagnosed with left adrenal cyst and was intensively followed up with plans for examination with diagnostic imaging.
