Foetus-in-fetu (FIF) is a rare congenital condition in which a vertebrate foetus is incorporated within its twin. The authors report the case of a newborn girl with prenatal ultrasonographic diagnosis of an intra-abdominal mass. Abdominal ultrasonography and computed tomography of the abdomen showed a heterogeneous cystic mass containing multiple calcifications. The patient had a laparotomy at 18 days of age with excision of a well-encapsulated 6 x 5 cm retroperitoneal mass, containing many organs. Anatomicopathologic examination showed a relatively well-differentiated FIF attached to an amniotic sac by a rudimentary umbilical cord...

Spermatozoa ultrastructure was studied in five marines (Paralonchurus brasiliensis, Larimus breviceps, Cynoscion striatus, Micropogonias furnieri, Menticirrhus americanus, Umbrina coroides, Stellifer rastrifer), and one freshwater (Plagioscion squamosissimus) species of Sciaenidae and one species of Polynemidae (Polydactylus virginicus). The investigation revealed that, in all species, spermatozoa display a round head, a nucleus containing highly condensed, filamentous chromatin clusters, no acrosome, a short midpiece with a short cytoplasmic channel, and a flagellum showing the classic axoneme structure (9+2) and short irregular lateral fins...

Fetus-in-fetu (FIF) is a rare congenital condition in which a vertebrate fetus is incorporated within its twin. The authors report the case of a newborn boy with prenatal ultrasonographic diagnosis of intraabdominal mass, provoking compression of the left kidney. Plain abdominal radiography, ultrasonography, and computer tomography showed a cystic mass containing multiple calcifications. Pathologic examination showed an irregular fetiforme mass, weighing 8 g, attached to an amniotic sac by a rudimentary umbilical cord with 2 rudimentary limbs, vertebral bodies, encephalus, coroidal plexus, stomach, duodenum, bowel, adrenal glands, upper and lower respiratory tissue, spleen, lymphoid tissue, single cavity heart, and kidney...

Sturge-Weber Syndrome (SWS) is characterized by facial flammeus nevus, leptomeningeal angiomatosis and coroidal hemangioma and MRI and CT scans are used to disclose the angiomatosis and secondary brain lesions. We review the CT and/or MRI scan of 26 patients with SWS. In 75% of cases the SWS was unilateral and in 25% bilateral, being the angiomatosis more frequent on occipital lobe (93%) than on the parietal (83%), frontal (53%) and temporal (53%) lobe. Diencephalon was involved in 13%, midbrain in 6% and cerebellum in 6% of cases...

CASE REPORT: A case of an immunocompetent patient presenting primary systemic toxoplasma infection involving the eye (condition seen in less than 3% of primary infections). The patient showed reactivation of this primary focus two years later. DISCUSSION: Diagnosis of toxoplasm retinitis is based on a typical lesion consisting in an area of active retinitis adjacent to an inactive corioretinal scar. Differential diagnosis must consider other causes of retinal coroiditis in primary infection cases: sarcoidosis, tuberculosis, syphilis as well as viral and fungal infections...

A 56-year-old right-handed male with a history of hypertension and diabetes presented two episodes of stroke: The first affected territory was the left anterior coroidal artery (capsular and paracapsular infarcts at the level of the genu and posterior arm of the internal capsule) and the second was the right thalamus, due to a hematoma. Following the first stroke, the patient developed severe dysarthria and after the second stroke remained anarthric. The pathophysiology of the disorder is discussed, and the role of the left and right thalamus as far as speech is concerned is reviewed...

The feeding biology of eight species of benthivorous fishes was studied in a sandy shore at Anchieta Island, south-eastern Brazilian coast. The fishes fed mainly on Amphipoda and Mysidacea crustaceans. The diet of the most abundant species, the drum Umbrina coroides, was analyzed in three standard length classes (20-55, 56-90 and 91-135 mm). This sciaenid showed an ontogenetic diet shift from Mysidacea to Amphipoda. The feeding behaviour of the sciaenid U. coroides and the gerreid Eucinostomus gula was recorded while snorkeling...

The paper presents the case of a 6 and a half year-old child, with marked hipotrophy in height and weight (15 kg weight, which make a deficit of about 6 kg). The right eye presented pupilar sinekies, loaded vitreous and two white-yellow exsudative coroidal placards. One of them was inter-maculo-papilar having 4DP in diameter, difuse margins and aspect, the other was infero-macular. The right eye vision was only 2/50 n.c. The child also presented cronical labial herpes and interstiţial pneumony. The ELISA test (+) confirmed the HIV suspicion...

The authors described a 39 year old woman affected by epidermal nevus syndrome, with cutaneous (verrucous epidermal nevus), skeletal (thoracolumbar levoscoliosis and frontal bossing) and ocular (papillar coloboma and coroideal nevus) defects. Moreover the patient presented vascular malformations and hamartomas: lymphangioma circumscriptum of the mammary area, left peroneal Gorham's disease, artero-venous acral tumour of the left foot and multiple artero-venous shunts of the lower limbs. Since puberty, hemodynamic modifications have caused pseudo-Kaposi of Bluefarb-Stewart of legs and feet and malleolar painful ulcers...

According to the diagnostic criteria currently in use, the so-called "unilateral" forms of the moyamoya disease, or rather those in which the disorders of the disease itself--such as occlusion of the internal supraclinoid carotid artery or its terminal branches and development of abnormal collateral circulation in the region of the basal ganglia--are only found in one hemisphere and should be considered as "probable" forms of the disease with a much lower incidence than the bilateral or "defined" forms of the same...

Proliferations fo the retinal pigment epithelium over malignant malanoms of the coroid were examined in the following regions: 1. at the posterior pole, 2. in the equator region, 3. in the ora region. The pigment epithelial cells exist in each proliferation in a differently marked pattern of mono- and double layers. Furthermore the proliferations show a varying amount and localisation of a fine fibrillar substance. The majority of the proliferated pigment epithelial cells at the posterior pole are loosely arranged to mono and double layers...
