Splenogonadal fusion (SGF) is a rare congenital malformation, which can be of a continuous or discontinuous type. It is characterized by splenic tissue fused with gonadal tissue. Because it lacks characteristic features, very few cases of SGF have been diagnosed preoperatively. Herein, we present a case with left side SGF who was diagnosed by 99mTc-nanocolloid spleen scintigraphy.

SUMMARY:The aim of this study was to determine the normal values of brain ventricles and indices in healthy subjects in our population using magnetic resonance imaging (MRI) and to reveal sex and age related differences. The MRI of two hundred-sixty-five healthy individuals aged between eighteen and eighty-seven years were examined and the midsagittal and axial images were used for measurements. The measurements were performed from MRI on a Workstation. The following mean values of brain ventricles and indices were observed; frontal horn width (FHW) (33.14 mm); third (3rd) ventricle width (TVW) (3.37 mm); fourth ventricle anteroposterior width (FVWAP) (9.93 mm); fourth ventricle transverse width (FVWT) (12.40 mm); and the maximum transverse inner diameter of the skull (TIDS) (128.75 mm) in females. The same dimensions were 34.85 mm, 3.91 mm, 10.26 mm, 12.81 mm, and 134.68 mm in males, respectively. There were statistically significantly differences in the frontal horn width, third (3rd) ventricle width, and the maximum transverse inner diameter of the skull values in between sexes. The mean values of Evans' index which obtanied with maximum width between the frontal horns of the lateral ventricles divided by the maximum transverse inner diameter of the skull were found as 0.280 ±0.172 in females; whereas the same dimensions were calculated 0.276±0.161 in males. These values were lower in healthy male subjects than females, however; there were no found significantly difference between groups. Present findings obtained from MRI are necessary anatomical baseline data for interpreting pathological changes, planning surgery, and determining presence and progress of some neurological diseases.

The aim of this study was to identify sphenoid sinus dimensions; and distance between columella nasal and sphenoid sinus; and columella nasal and hypophysis in healthy adult subjects using magnetic resonance imaging (MRI) and to evaluate differences between genders and age groups. The MRI results of 300 healthy subjects (192 females; 108 males) aged 18-68 years were studied. The midsagittal and axial images were used for shape of the sphenoid sinus, and the distance measurements of its related adjacent structures on MRI. The mean values of the distance between columella nasal; and columella nasal and hypophysis; and sinus sphenoidalis width were 65.73±5.22 mm, 87.05±4.79 mm and 37.67±8.40 mm in females respectively, whereas the same values were 71.79±5.06 mm, 94.52±6.07 mm and 41.95±9.32 mm in males, respectively. The means of all measurements were lower in healthy female subjects than in healthy males.Additionally, the classification of sphenoid sinus types were determined to be postsellar type (131), sellar type (46), presellar type (14) and conchal type (1) in females, respectively. The same measurement were determined as postsellar type (82), sellar type (23) and presellar type (3) in males, respectively. Differences between sexes and age related changes were observed in the variations of the size, location and shape of sphenoid sinus were observed The observations presented in this report have defined anatomic parameters that need to be taken into consideration for reference data to determine gender discrepancies, age related changes and helpful for radiologists and clinicians to plan safe surgical approach and avoid surgical risks.
