Introduction

Imperforated hymen incidence is 0.014-0.01% [1]. The presentation mostly late with amenorrhea at the adolescence age. Specific causes for the failure to set up patency are not clear. The cause may be related to failure of apoptosis due to a genetically transmitted signal, or it may be related to an inappropriate hormonal milieu [2]. Familial inheritance in successive generations has been described [3]. Hydrocolpos is an accumulation of reproduction gland secretion and cystic dilation of the vagina due to imperforate hymen or congenital anomalies of the vagina like; vaginal atresia or membranous obstruction in the lower part of the vagina [4-7]. If the condition not diagnosed early, could be renal failure develops due to lower renal obstruction. Our case is female, she was actually diagnosed to have pelvic-abdominal mass, at birth by examination; she had abdominal distention and imperforate hymen.

Case Report

Second-degree consanguineous parents, they had no family history of congenital anomalies. Mother, she had good antennal care, at 39 weeks gestation age, antenatal ultrasound showed the fetus had pelvic-abdominal mass 4 × 6 cm (Figure 1).

She was born at 40 weeks gestational age, by normal vaginal delivery, Apgar score were 7, 9 at 1, 5 minute respectively. Birth weight was 3300 grams and head circumference was 36 cm. She had abdominal distension in the lower part, by palpation, there is a tender mass with a diameter of about 6 cm (Figure 2). The other parts of the physical examination is normal. She has a normal patent anus and she passed stool. she has a patent normal urethral opening and passed urine 3 ml/kg/day. She had imperforated bulging hymen (Figures 3-5). Abdominal ultrasound showed cystic abdominal mass measure about 5 × 8 cm, there were left-sided hydronephrosis and hydro ureter.

Figure 5: Axial view CT-hydrocolpos.

Abdominal CT showed cystic mass extended from the pelvis the level of the hymen, the mass was not connected to the internal organ or spine. The mass made pressure on urine bladder which was pushed anteriorly. Clinical presentation and abdominal CT was diagnostic of imperforate hymen with hydrocolpos. The pediatric surgeon did a hymeneal incision and a large amount of milky secretion was drained. The abdomen distension significantly subsided. The baby was discharged home to be operated next week under general anesthesia for appropriate vaginoplasty.

Investigation

Serum urea-20 mg/dl; Creatinine-0.3 mmol/l; Sodium-135 mmol/l; Potassium-4 mmol/l; Calcium-1.14 mmol/l.

Discussion

By antenatal ultrasound, the fetus had lower abdominal mass at the age of 39 weeks gestation. By physical examination after birth, she had visible abdominal distension, abdominal ultrasound showed pelvic cystic mass not connected to the internal organ but had pressure on the left side causing hydro-ureter and hydronephrosis, abdominal CT showed cystic mass extended from pelvis to lower part of vagina till hymen. The CT showed also cystic mass made pressure on the urine bladder which was pushed anteriorly. Physical examination also showed bulging imperforated hymen. The clinical examination and the radiologic findings were diagnostic of neonatal imperforated hymen and hydrocolpos. The diagnosis at the time and the appropriate management of pediatric surgeon by hymeneal incision saved the baby from a fatal complication [8,9].

Conclusions

• The genital area of the female new-born should be examined well after birth.

• Early diagnosis and at appropriate management will protect the patient from a fatal complication.
