Abstract

Objective: We
evaluated adipose tissue distribution in different anatomical localizations by comparing
with epidural fat tissue.

Methods:
Sixty patients’ (28 female and 32
male) included in our study had abdominal computerized tomography and lumbar
magnetic resonance images evaluated retrospectively. Subcutaneous and
intraabdominal fat tissue thickness was compared with perirenal and epidural
fat. The relationship with demographic characteristics of patients was
investigated.

Results:
Mean value of subcutaneous fat thicknesses were higher in females (29.9±24.2 mm
in females and 16.2±24.5 mm in males), while perirenal fat tissue area was
higher in males than females (2118.4±2327.1 mm² and 1204.1±851.3 mm²
respectively). There was no significant difference in intraabdominal and
perirenal fat tissue measurements according to gender (p=0.407, p=0.390;
respectively). Also subcutaneous, intraabdominal and perirenal fat tissue
measurements showed increments in association with gender (r=0.33, p=0.010;
r=0.37, p=0.004; r=0.51, p=<0,001; respectively); however no relationship was
detected with epidural fat area (p=0.519). Subcutaneous and intraabdominal fat
thicknesses were not related with epidural fat (p values 0.434 and 0.271,
respectively); and there was a statistical relationship between perirenal and
epidural fat (p=0.010).

Conclusions: Increases
in subcutaneous and intraabdominal fat tissue thickness with waist
circumference was an expected finding, but no correlation was detected with
epidural fat. Thus, we think that the amount of epidural fat does not change
with obesity. Also, we concluded that while perirenal fat measurements were
higher in the male group and correlated with epidural fat, androgenic effects
can play a role in changing the amount of perirenal and epidural fat tissue. This
result may be helpful in management of epidural pathologies, though there is a
need for supportive studies.
