Introduction: Adnexal masses consist of anomalies which can be noticed in any age of women. These abnormalities determine different features during reproductive age, entail surgical treatment, and are monitored with clinical and laboratory findings. Adnexal masses may result from benign or malignant lesions of ovarian, tubal, and para tubal origin, as well as pregnancy-related causes such as ectopic pregnancy. The study intends to evaluate the adnexal masses by laparoscopy among patients admitted to Bangabandhu Sheikh Mujib Medical University from March 2016 to August 2016. Methods: This cross-sectional study was carried out at Bangabandhu Sheikh Mujib Medical University, Dhaka. The sample was collected by the purposive consecutive sampling method. Subjects were selected by appropriate inclusion criteria. Data were collected after appropriate verbal consent from the guardian of patients and the result was subjected to standard statistical evaluation and was analyzed by the SPSS programme. Result: This study shows the average age was 27.82 years. Regarding parity majority (31, 62.0%) were nulliparous women and the majority (31, 62.0%) were from a lower-middle-class families. The primary complaints in the study group (27, 54.0%) were dysmenorrhoea followed by infertility (21, 42%). Eighteen women (18, 36.0%) complained of dyspareunia. Twenty-six patients (26, 52.0%) had tender mass. Size of the uterus, twenty-two (22, 44%) patients had an enlarged uterus. The commonest finding was tubo-ovarian mass in thirteen (13, 26.0%) patients followed by an endometriotic cyst in twelve patients (12, 24%). The findings of diagnostic laparoscopy, maximum (22, 44.0%) were enlarged uterus followed by fourteen patients (14, 28.0%) who had ovarian cysts. Conclusion: This study observed laparoscopic findings are far way better than ultrasonography. As a result, laparoscopy is a gold standard for the estimation of patients with pelvic adnexal masses.
