The mean age of these SRCT cases was 6.3± 1.6 (range: one month-19) years.

The higher proportion of cases was reported in the age of 1-5 years, contributed for 43.5%.

Male to female ratio is 59/108 vs.

49/108, respectively, the male to female ratio being at 1.2 to 1.0.

Conclusions: The mean age of SRCTs cases was 6.3± 1.6, ranging from one month to 19 years.

The higher proportion of SRCTs cases was reported in the age ranging from 1-5 years; with a ratio of males to females being 1.2 to 1.0.
