Duplication of the inferior vena cava (IVC) is the most common anomaly to affect the vena cava. Variations in the IVC are diagnosed in routine dissection studies, in retroperitoneal surgeries, or in computerised tomography (CT) sections ordered for various reasons. In this paper we present two cases of a double IVC together with the CT findings. The duplication might have occurred during embryological development. Although venous anomalies are rare, they have particular importance with respect to the interruptions that may occur during retroperitoneal and thoracic surgery or in the treatment of thrombo-embolic disease.

This study has been designed to estimate the volume fraction of the brain ventricles volume to total brain volume and to correlate them with gender and age in normal subjects. Cranial computed tomography (CT) images of 80 normally evaluated subjects (five female and five male for each decade) were selected from 1,073 CT examinations. The volumes of total brain, cerebral aqueduct, fourth, third, and lateral ventricles and their ratios were estimated using the Cavalieri method and volume fraction-stereological methods. The ratio of total brain ventricle volume to total brain volume was comparable between the two genders (p > 0.05, independent t test). Mean volume fraction of total ventricle volume to total brain volume was found to be 1.21% in the first and 3.37% in the last decades. Mean volume fraction was found to increase significantly with age (p < 0.01, r = 0.630, Pearson). In conclusion, the mean percentage of total ventricle volume within the total brain volume was found to be 2%. We demonstrated the volume fraction of total ventricle to total brain in normal subjects. Total ventricle volume to total brain volume fractions can be important tools in determining ventricle volumes, which denote variability in some diseases (Alzheimer, schizophrenia, neurodegenerative disorders, etc.) and can be estimated by stereological methods.

Using computerized tomography 7 human fetuses were examined, aging 24 to 39 weeks. Frontal sinus developes in the region of frontal recess of the frontal nasal meatus in a fetus aging 27 weeks. In the latter weeks of the fetal life the frontal recess of the middle nasal meatus transforms upwards into an oval thin-walled space corresponding to the developing frontal sinus. It adheres to the ethmoidal slabyrinth, integrating with it.

A CT study was performed on 8 foetuses aged between 20 and 38 weeks. In foetuses at the 20th week the semicircular canals, the spiral canal of the cochlea and the initial (labyrinthine) part of the facial canal are visible. At week 24 the tympanic part of the facial canal is observed. In the 31st week the cochlea is divided into 2 compartments, and in the 38th week the vestibular aqueduct and osseous labyrinth are seen.

Even though much has been written on the aetiology of globus pharyngeus, it still remains elusive and multifactorial. We present a case of a 54-year-old woman who was referred by an orthopedist to the radiology department with a 6-day history of an intense feeling of “pressure” and “tightness” in the jugular notch. After performing a contrast-enhanced computed tomography scan, a phlebectasia of the right anterior jugular vein was discovered. When trying to determine the cause of the globus sensation one has to consider the possible existence of a phlebectasia of one of the jugular veins. (Folia Morphol 2013; 72, 3: 278–280)

The aim of the study was to investigate the distribution of the circle of Willis variants in Polish population by means of computed tomography angiography (CTA). The results were then analysed and compared with another study that used similar methods but that was carried out on an ethnically distinct population. Patients presenting with intracranial pathology were excluded from the initial study population. In total, 250 CTA belonging to 129 female and 121 male patients were reviewed. A modified classification system of the circle was proposed, which took into consideration the anterior and the posterior aspects of the circle individually. The typical variant of Willis’s circle occurred in 16.80% of cases. The anterior and the posterior portions of the circle were normal in 47.20% and 26.80% of the patients respectively. As for the anterior part, lack of the anterior communicating artery was the most frequent abnormality (22.80%). Bilateral absence of posterior communicating arteries was the most common anomaly in the posterior part of the circle (29.20%). This type of anomaly was also the most common, when taking into consideration the entire circle (12.00%). There were statistically significant differences between the age groups and genders when considering the occurrence of an incomplete circle. Overall, a substantial proportion of patients manifested clinically important variants that were incapable of providing collateral circulation. Comparison with other imaging-based and cadaveric studies revealed noticeable differences, that may have resulted from the variable technical features of other studies or other factors such as the ethnical origins of the studied populations.

Background: Frontal sinuses are 2 irregular cavities, placed between 2 lamina of frontal bone. Expansion continues during childhood and reaches full size after puberty. Persistent metopic suture is one of the factors that are related to abnormal frontal sinus development. In this study, we want to discuss about the coexistence of persistent metopic suture and abnormal frontal sinus development using radiological techniques. Materials and methods: In this retrospectively planned study, images of 631 patients were examined, 217 (34.4%) of them were men and 414 (65.6%) of them were women. Brain computed tomography and magnetic resonance images were retrieved from the electronic archive for analysis. Results: In this study, frontal sinus development is categorised as right side atrophy, left side atrophy, bilateral atrophy and bilaterally developed sinuses. The presence of metopic suture was accepted as persistent metopic suture. Frontal sinus atrophy was found in 22.7% and persistent metopic sutures were found in 9.7% of overall. Conclusions: In this study, no significant results were detected that were related to the frontal sinus agenesis or dismorphism associated with persistent metopic suture. We conclude that, although publications propounding metopism that leads to abnormal frontal sinus development are present in the literature, no reasonable explanation has been mentioned in these articles; and we believe that these findings are all incidental.

There is no agreement in the literature as to the time of the onset and progress of the vertebral column ossification. The aim of the present study was to determine the precise sequence of ossification of the neural arches and vertebral centra. Histological and radiographic studies were performed on 27 human foetuses aged from 9 to 21 weeks. It was found that the ossification of vertebrae commences in foetuses aged 10 and 11 weeks. Ossification centres appear first for neural arches in the cervical and upper thoracic vertebrae and by the end of 11th week they are present in all thoracic and lumbar neural arches. In the vertebral centra in foetus of 10 weeks ossification was found in the lower 7 thoracic and first lumbar vertebrae. By the end of 11th week ossification is present in the lower 4 cervical, all thoracic, all lumbar and 4 sacral vertebral centra. The study indicates that ossification of the neural arches proceeds in the craniocaudal direction, whereas in the vertebral centra it progresses from the lower thoracic vertebrae into both directions. Different shapes of ossification centres were also described. (Folia Morphol 2013; 72, 3: 230–238)

Quadricuspid pulmonary valve (QPV) is an uncommon congenital defect reported in the general population with a frequency of up to 0.25%. The defect usually does not cause severe clinical complications and its presence frequently remains clinically silent. Moreover, there are several difficulties in visualization of pulmonary valve using basic diagnostic modalities such as echocardiography. Therefore, in the majority of cases, QPV is detected accidentally during cardiac procedures or post mortem. The authors present a case of QPV complicated with aneurysm of the pulmonary trunk, diagnosed with computed tomography in 70-year-old woman. Although the patient had undergone transthoracic echocardiography examinations several times in the past, only computed tomography allowed the detection of the anomalous valve. In addition, the examination confirmed aneurysm of the pulmonary trunk. To the best of our knowledge, this is the first case of QPV diagnosed in vivo with computed tomography.

Stosowanie analizy obrazu do badań struktury wymaga określenia metody odróżnienia punktów obrazu należących lub nie do obiektów. Przedstawiono algorytm binaryzacji obrazów tomograficznych gleby zagregowanej, który skonstruowano w oparciu o warunek równości porowatości struktury obliczonej z tomogramu przed i po segmentacji. Podano sposób na wyznaczenie porowatości struktury z obrazu tomogramu. Wymaga on znajomości współczynnika Hoansfielda materiału, z którego zbudowane są agregaty glebowe. Założono, że jest równy wartości odpowiadającej położeniu maksimum histogramu współczynników Hounsfielda, znajdującemu się w obszarze dużych jego wartości. Przyjęto jednakowe wartości współczynnika tego dla gleby nieodkształconej i poddanej procesowi ściskania (odkształcenie względne 13 %),

An autopsy or necropsy can be performed only once; therefore, its proper execution is of fundamental importance in explaining the cause of death. The protocol with photographic documentation is an integral part of the autopsy, but sometimes it does not fully reflect the state of the body and the pathological changes observed at each stage of the procedure. These shortcomings are addressed by modern imaging techniques, which are increasingly used during the autopsy of human bodies, but quite rarely during necropsy of animals. Non-invasive techniques (CT, MRI, or photogrammetry with laser body scanning), or in some cases also minimally invasive techniques (biopsy), enable comprehensive analysis of the carcass, but Virtopsy is only a supplement to the classical autopsy, especially in veterinary forensic medicine.

Artykuł zawiera krótkie omówienie zasady działania tomografii komputerowej. Zwrócono uwagę, że stosując metodę analizy obrazów do pomiarów parametrów geometrycznych agregatów glebowych zawartych w obrazach tomograficznych, konieczne jest określenie zależności między wielkością minimalnego, dającego się parametryzować agregatu, a rozmiarami woksela. Wykonano analizą tomogramów rzeczywistych oraz uzyskanych metodą symulacji komputerowej dla monoagregatowych struktur (agregaty od 1 do 7mm). Stwierdzono, że warunkiem ilościowej analizy jest aby rozmiar agregatu był przynajmniej 10 razy większy od woksela.
