Case Presentation: A 28-year-old female presented to the emergency department complaining of right lower abdominal pain. A contrast-enhanced computed tomography (CT) was done, which showed a 15-centimeter right adnexal cyst with adjacent “whirlpool sign” concerning for right ovarian torsion. Transvaginal pelvic ultrasound (US) revealed a hemorrhagic cyst in the right adnexa, with duplex Doppler identifying arterial and venous flow in both ovaries. Laparoscopic surgery confirmed right ovarian torsion with an attached cystic mass, and a right salpingo-oophorectomy was performed given the mass was suspicious for malignancy. Discussion: Ultrasound is the test of choice for diagnosis of torsion due to its ability to evaluate anatomy and perfusion. When ovarian pathology is on the patient’s right, appendicitis is high in the differential diagnosis, and CT may be obtained first. Here we describe a case where CT first accurately diagnosed ovarian torsion by demonstrating the whirlpool sign, despite an US that showed arterial flow to the ovary. Future studies should determine whether CT alone is sufficient to diagnose or exclude ovarian torsion.

Paratubal Cyst

A 30-year-old woman (gravida 0) visited our hospital with a complaint of right lower abdominal pain. Transvaginal ultrasonography revealed a 5-cm swollen right ovary, which was suspected to be a mature cystic teratoma. Pelvic examination revealed moderate pain. Contrast-enhanced computed tomography showed a 44-mm cystic mass containing fat and calcified material in the right pelvis. Since torsion was suspected, emergent laparoscopic surgery was performed. Intraoperative findings were a swollen right ovary without torsion or congestion. Two small pedunculated 1- and 2-cm diameter paratubal cysts that grew from almost the same place of the ampulla of the right fallopian tube were observed. The thin stalk of the 1-cm paratubal cyst was entangled around the stalk of the 2-cm paratubal cyst, with its head congested. Through a small abdominal laparoscopic incision, the tumor of the right ovary and the two paratubal cysts were excised. Histopathological examination revealed that the right ovarian tumor was a mature cystic teratoma, and the two paratubal cysts had no malignancy. This case showed that only a 2-cm tumor with congestion caused the acute abdomen.

A 77-year-old man, who was on anticoagulation, presented with a painful lump on the right abdominal wall. Laboratory tests showed slight anaemia and elevated inflammatory markers. Abdominal plain computed tomography (CT) revealed a mass in the right rectus abdominis muscle. He was admitted with a diagnosis of primary rectus abdominis haematoma. However, on the next day, the diagnosis was corrected to primary rectus abdominis abscess, following contrast-enhanced CT of the abdomen. This case illustrates the importance of considering primary rectus abdominis abscess in patients with suspected primary rectus abdominis haematoma, and contrast should be used when performing CT.

AbstractThe incidence of abdominal cysts in infants is 1 in 500 to 1 in 1,000 live births. Among the ovarian cysts in infants, serous cystadenoma is extremely rare with only few reported cases in the literature. Here, we report a case of a giant neonatal ovarian serous cystadenoma treated with laparoscopic cystectomy and confirmed by histopathological examination.A 27-year-old delivered a female baby with uneventful caesarean section at full term. The antenatal ultrasonography (USG) in third trimester had showed an abdominal cyst in the left side of the abdomen. Postnatal USG was suggestive of omental cyst. A contrast-enhanced computed tomography scan of the neonate showed a large cyst occupying the entire abdomen. On laparoscopic evaluation, a cystic mass filled with 500 mL of clear yellow fluid was seen in the left pelvic fossa. Left ovary could not be visualized separately. The right ovary, fallopian tubes, and uterus were normal. The entire cyst was removed and sent for histopathological examination. On gross examination, a unilocular cyst measuring 10×8×6.5 cm with a wall thickness of 0.2 cm was noted. On microscopic examination, the histomorphological features were consistent with serous cystadenoma of the ovary. There is a paucity of literature regarding pathological diagnosis of such cases and hence we report one such case.

Background: Endometriosis mainly affects female pelvic tissues and organs, and the presence of endometriosis in the kidney is extremely rare.Case Presentation: We report a case of a 48-year-old woman who presented with intermittent hematuria. She was found to have a cystic mass on renal ultrasonography, and contrast-enhanced computed tomography (CT) showed slight enhancement of the cystic wall and septa. These findings were indicative of cystic renal tumor. The patient subsequently underwent partial right nephrectomy. Histopathology revealed endometriosis of the right renal parenchyma. The patient recovered well and had no evidence of a recurrent renal mass at the 3 months' follow up.Conclusion: The possibility of renal endometriosis should be considered in a female patient with a cystic renal mass and clinical symptoms related to the menstrual cycle.

<p>Giant tonsillolith is a rare clinical entity. We present the case of a 7 years old male who presented with sore throat and difficulty in swallowing. Right tonsil was bulging into the oropharynx with marked peritonsillar swelling and inflammation and a provisional diagnosis of peritonsillar abscess was made. Contrast enhanced computed tomography scan revealed a large-sized tonsillolith on the right side. The patient underwent elective stone removal and tonsillectomy.</p>

AbstractTeratoma can be defined as a true neoplasm that contains tissues that either are foreign to the primary site of origin or are histologically diverse and represent more than one of the embryonic germ layers. A 20-year-old female patient presented with chief complaints of swelling in the right upper abdomen since childhood and back pain for the past 4 years. Per abdomen, examination revealed a lump of around 15 cm in size in the right hypochondrial region extending to the epigastric region. Contrast-enhanced computed tomography abdomen revealed a 14.3 × 14.1 × 17.4 cm well-defined heterogeneously hypoattenuating nonenhancing complex cystic mass with focal areas of calcifications and fat attenuation in retroperitoneum. The patient was taken up for exploratory laparotomy and a tumor was found in the retroperitoneum, retrocavally and was excised with due care. Histopathological examination features were suggestive of mature cystic teratoma. The postoperative stay was uneventful.

Polypoid Tumor

We present a rare cause of intestinal obstruction in an adult, due to ileo-colic intussusception by a lipoma of the ileo-cecal valve and its ultrasonographic presentation. The case presented in emergency for spontaneously appearing and disappearing palpable elastic mass in the right iliac fossa. The ultrasonographic examination raised the suspicion of an ileo-colic intussusception due to a polypoid tumor. The contrast-enhanced computed tomography confirmed the finding and suggested that the polypoid tumor was more likely a lipoma. Right hemicolectomy and cholecystectomy were performed and the pathological examination confirmed the lipoma. The evolution of the patient was favourable and uneventful.
