A case of missing mitral valve leaflet: radiological detection.

Intravascular foreign bodies may be introduced into the circulation as a complication of minimally invasive or interventional techniques, or during cardiac valve surgery. Prosthetic heart valve leaflets have been rarely described as intravascular foreign bodies. Herein we report a case of prosthetic heart valve leaflet embolization to the aortic bifurcation with computed tomography and ultrasonography findings, and the importance of radiographic imaging in the localization of missing leaflet fragment is pointed out.

The measurement of the rotational deformities with computed tomography in femoral shaft fractures of the children treated with early spica cast.

Twenty-eight children with femoral shaft fractures, treated with early spica cast, were evaluated with computed tomography (CT), for their femoral shaft rotational deformities. The femoral torsion angles were measured on both sides. If the torsion angle of the fractured side was more than the other side, it was considered as an internal rotational deformity and if it was less, it was considered as an external rotational deformity. Internal rotational deformities were detected in nine cases and external rotational deformities were detected in 17 cases. Rotational deformity was not observed in two cases. Four cases, with a rotational deformity more than 10 degrees, were corrected with a gypsotomy through the level of the fracture. We concluded that a rotational deformity, which is an important complication in conservative treatment of the femoral shaft fractures in children, can be determined exactly with CT and corrections on the spica cast can be made with a gypsotomy.

Subcutaneous undifferentiated sarcoma induced by N'-ethyl-N'-nitrosourea in rat: radiology, histopathology and mutagenesis.

The aim of the present study was to investigate high dose and long-term effects of a common industrial agent, N'-ethyl-N'-nitrosourea (ENU), on soft tissues in a rat model. ENU, which was dissolved in polyethyleneglycol (PEG) was injected intra-peritoneally once a week (300 mg/kg) in the first experimental group. The second group received only PEG. The control group was free of any agent administration. Only rats treated with ENU for a period of 45 weeks developed large subcutaneous tumours (approximately 5-9 cm in size). Tumoral tissues were examined radiologically, histopathologically and immunohistochemically. There was no bone destruction beneath the soft tumoral tissues in direct X radiograms. Computed tomographic (CT) images showed heterogeneous soft tissue masses with a density ranging from 50 to 65 HU. Macroscopically, all tumors were circumscribed with a gray-white surface in the cross-sections. The histopathological and immunohistochemical examination of the subcutaneous tumoral tissues showed a spindle cell type of sarcoma. Lymphatic and skeletal muscle invasion, atypical mitoses and necroses were determined in all tumoral tissues in the experimental group. A somatic point mutation was detected in exon 2 of KRAS oncogene in sarcoma tissues using the single strand conformational polymorphism (SSCP) analysis. In conclusion, the activated KRAS oncogene might contribute to the progression of subcutaneous sarcoma in experimentally ENU induced rats due to point mutation.

Disseminated pneumocephalus secondary to an unusual facial trauma.

Pneumocephalus can be secondary to a postintrathecal procedure, sinus fracture, basilar skull fracture, congenital skull defect, neoplasm, gas producing organism, barotrauma, neurosurgery, paranasal sinus surgery, mask or nasal continuous positive-airway pressure. Unusual facial traumas can also be rare causes of pneumocephalus. Here, we present such a case in whom an air compressor tip injury to both eyes led to the disseminated pneumocephalus. We report this rare case with the computed tomography findings and try to explain the possible mechanism of the pnemocephalus.

Primary diffuse tracheobrochial amyloidosis: case report.

Respiratory amyloidosis is a rare disease that occurs in three forms: tracheobronchial, nodular parenchymal and diffuse parenchymal involment. Tracheobronchial amyloidosis is characterized by focal or diffuse deposition of amyloid in the submucosa of the trachea and proximal bronchi. Herein, we report a case of diffuse tracheobronchial amyloidosis with plain radiography and thorax computed tomography findings.

Inferomedially projecting pneumatised secondary middle turbinate.

Secondary middle turbinate (SMT), a rare variation of the nasal cavity, is a bony projection covered by soft tissue that arises from the lateral nasal wall. It is almost always bilateral and usually projects superomedially without any ostiomeatal unit obstruction. Herein, we report a case of bilateral inferomedially projecting secondary middle turbinates, one of which is pneumatised and hypertrophied, resembling a large ethmoid bulla extending into the middle meatus. The recognition of this variation is important since it may predispose to inflammatory sinus disease, by narrowing the ostiomeatal unit.

Normal thyroid volume by ultrasonography in healthy children.

With the objective of creating standards for the volume of the thyroid gland by ultrasonography in the 0-16-year age group, thyroid volumes of 302 healthy children (150 boys, 152 girls) were measured by ultrasonography. The transverse (x), sagittal (y) and anteroposterior (z) lengths of the right and left lobes and isthmus were measured. Volumes of these were calculated by the ellipsoid volume formula [V = (pi/6) x x x y x z]. Statistical analysis was done using the Kruskal-Wallis and Student t tests. The cases were divided into six and eight groups by age and height, respectively. There was a significant positive correlation between thyroid volume, age, height and weight. Thyroid volumes in children of 12 years and over were significantly different from those in the younger age groups.
