[INTRODUCTION - The glove-finger phenomenon observed on chest plain film is characterized by branching tubular or fingerlike opacities that originate from the hilum and are peripherally directed. This change brings about impaction and inspissation of the mucus and inflammatory debris besides the obstruction of bronchi and of its prestenotic dilatation about. CASE REPORT - A 51 year old male patient presented with coexisting bronchial asthma and microcellular carcinoma of left 2nd pulmonary segment, leading to a tubular type glovefinger phenomenon. The diagnosis was proved by decrease of Tiffeneau’s index, bronchoscopy, bronchocytology and bronchogenic biopsy. CONCLUSION - The glove-finger phenomenon is correctly visible on postero-anterior chest plain film. The dilated and mucus-filled bronchi are not visible on radiography if the sorrounding lung is atelectasic. Because obstructive and nonobstructive bronchogenic diseases can appear with similar presentation, therefore, definitive diagnosis is only possible on the basis of pneumodynamic examinations, bronchoscopy, bronchocytology and biopsy.]

[Ethiopathogenesis of polycystic ovarian syndrome and imaging diagnostics of polycystic ovary]

JAKAB Attila, MOLNÁR Zsuzsanna, TÓTH Zoltán

[Polycystic ovarian syndrome is a heterogenous syndrome with a wide variety of endocrine and metabolic abnormalities and clinical symptoms. It is considered as the most frequent endocrine disorder in women in reproductive age and the most common cause of anovulatory infertility. Key features include menstrual cycle disturbance, hyperandrogenism and obesity. There are many extraovarian aspects to the pathophysiology of polycystic ovarian syndrome, but ovarian dysfunction is central. The underlying unique feature of the ovarian morphology gives the significance of the ultrasound examination. At a recent consensus meeting, a refined definition of the polycystic ovarian syndrome was agreed, encompassing a description of the morphology of the polycystic ovary. The subjective appearance of polycystic ovary should not be substituted for the definition. Further, a woman having polycystic ovary in the absence of menstrual disorder or hyperandrogenism (asymptomatic polycystic ovary) should not be considered as having polycystic ovarian syndrome, until more is known about the situation. Since ultrasound description of polycystic ovary morphology has central role in the diagnosis, and untreated polycystic ovarian syndrome carries long term health risks, the increasing attention to ovarian morphology may offer an effective tool to decrease women`s morbidity. This review outlines the background and feature of ovarian morphology in polycystic ovarian syndrome, and details the current ultrasound definition of polycystic ovary.]

[Breast core needle biopsies yielding uncertain results - Experience at the complex mammographic screening unit in Kecskemét]

AMBRÓZAY Éva, BORI Rita, LŐRINCZ Margit, LÓRÁND Katalin, CSERNI Gábor

[INTRODUCTION - On occasion core biopsies yield an inconclusive (B3 or B4) result in the triple diagnostics of breast lesions. These cases may turn to be malignant in the operation specimen. This study evaluates the value of B3 and B4 diagnoses and the consequences of these diagnoses. MATERIALS AND METHODS - Core needle biopsies were generally taken under imaging guidance with an automatic gun using G14 gauge needles. They were evaluated using internationally and nationally accepted categories from B1 to B5. The analysis was based on data collected between 2000 and March 2005. RESULTS - Of the 663 core needle biopsy specimens 31 (4.7%) were classified as B3 and 22 (3.3%) as B4. Specimens were more often fragmented in the latter category (a rate of 0.64 as compared with a rate of 0.26). Patients with a B3 diagnosis were operated on in 23 cases, eight of which turned to be malignant (0.35). B4 diagnoses were followed by operations in 21 cases and were found to be malignant on 19 occasions (0.9). Whenever a B4 diagnosis was associated with radiological findings of malignancy (category 5 on mammography and/or ultrasound) the cases unanimously proved to be malignant. The same association with B3 diagnoses yielded malignancy in a rate of only 0.67. CONCLUSION - Both B3 and B4 diagnoses represent an indication for operation. Our experience suggests that B4 diagnoses when coupled with a radiological opinion of malignancy can be candidates for definitive (therapeutic breast conserving) surgery whereas B3 diagnoses require diagnostic excisions.]

[The bubble-sign of spontaneous pneumoperitoneum]

SZÁNTÓ Dezső

[INTRODUCTION - Pneumoperitoneum is a reliable indicator of serious underlying damage. There are four etiologic categories of extraluminal-intraperitoneal gas collections: spontaneous, iatrogenic, traumatic and criminal perforations. The erect posteroanterior chest radiograph is the most sensitive plain film projection for detecting pneumoperitoneum and it may show 0.5-1 ml free abdominal gas when meticulous radiographic techniques (lateral, oblique, air-gap, lordotic, inspiratory and expiratory exposures) are used. The appearances of extraluminal gas collections are specified by physical rules and individual preferences. The bubble-sign is an uncommon, pathognomonic phenomenon. CASE REPORT - A case of an 86 years old female patient with spontaneous pneumoperitoneum, diagnosed on the basis of the bubble-sign is presented. On erect, lordotic inspiratory chest film, right medial inversion of diaphragm, left pleural effusion, emphysema, cardiomegaly and aortectasia were observed. The bubble-sign and hydromediastinum became evident in the right phrenicocostal angle on expiratory view. Our patient expired before the surgical intervention.The postmortem demonstrated double peptic duodenal ulcers; the older ulcer had penetrated and encapsulated in the hepatoduodenal ligament, while the more recent one perforated through the intraperitoneal space. CONCLUSION - Routine upright chest films are valuable screening tools for uncommon signs of pneumoperitoneum, also.]

Life threatening rare lymphomas presenting as longitudinally extensive transverse myelitis: a diagnostic challenge

TOLVAJ Balázs, HAHN Katalin, NAGY Zsuzsanna, VADVÁRI Árpád, CSOMOR Judit, GELPI Ellen, ILLÉS Zsolt, GARZULY Ferenc

Background and aims – Description of two cases of rare intravascular large B-cell lymphoma and secondary T-cell lymphoma diagnosed postmortem, that manifested clinically as longitudinally extensive transverse myelitis (LETM). We discuss causes of diagnostic difficulties, deceptive radiological and histological investigations, and outline diagnostic procedures based on our and previously reported cases. Case reports – Our first case, a 48-year-old female was admitted to the neurological department due to paraparesis. MRI suggested LETM, but the treatments were ineffective. She died after four weeks because of pneumonia and untreatable polyserositis. Pathological examination revealed intravascular large B-cell lymphoma (IVL). Our second case, a 61-year-old man presented with headache and paraparesis. MRI showed small bitemporal lesions and lesions suggesting LETM. Diagnostic investigations were unsuccessful, including tests for possible lymphoma (CSF flow cytometry and muscle biopsy for suspected IVL). Chest CT showed focal inflammation in a small area of the lung, and adrenal adenoma. Brain biopsy sample from the affected temporal area suggested T-cell mediated lymphocytic (paraneoplastic or viral) meningoencephalitis and excluded diffuse large B-cell lymphoma. The symptoms worsened, and the patient died in the sixth week of disease. The pathological examination of the presumed adenoma in the adrenal gland, the pancreatic tail and the lung lesions revealed peripheral T-cell lymphoma, as did the brain and spinal cord lesions. Even at histological examination, the T-cell lymphoma had the misleading appearance of inflammatory condition as did the MRI. Conclusion – Lymphoma can manifest as LETM. In cases of etiologically unclear atypical LETM in patients older than 40 years, a random skin biopsy (with subcutaneous adipose tissue) from the thigh and from the abdomen is strongly recommended as soon as possible. This may detect IVL and provide the possibility of prompt chemotherapy. In case of suspicion of lymphoma, parallel examination of the CSF by flow cytometry is also recommended. If skin biopsy is negative but lymphoma suspicion remains high, biopsy from other sites (bone marrow, lymph nodes or adrenal gland lesion) or from a simultaneously existing cerebral lesion is suggested, to exclude or prove diffuse large B-cell lymphoma, IVL, or a rare T-cell lymphoma.

TLR4 (Toll-like receptor-4) expression and frontal-cingulate volumes in schizophrenia

LI Hua, KÉRI Szabolcs

Evidence suggests that pathogen-associated pattern recognition receptors (Toll-like receptors, TLRs) are implicated in the pathophysiology of schizophrenia. TLRs are important in both peripheral immune responses and neuronal plasticity. However, the relationship between peripheral TLR expression and regional brain volumes is unknown in schizophrenia. We therefore assessed 30 drug-naïve, first-episode patients with schizophrenia. TLR4+/TLR1+ monocytes were measured using flow-cytometry. High resolution magnetic resonance images (T1 MRI) were obtained and analyzed with FreeSurfer. Results revealed significant negative correlations between the percentage of TLR4+ monocytes, mean fluorescent intensities, and brain volumes in frontal and anterior cingulate regions. The measures of TLR1+ monocytes did not show significant relationships with regional brain volumes. These results raise the possibility that abnormal TLR-activation is associated with decreased brain volumes in schizophrenia.

Investigation of risk factors, topographic location and stroke mechanisms of unilateral isolated and posterior cerebral ARTERY thalamic infarcts

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.
