Adnexal torsion is a relatively rare cause of lower abdominal pain in women, but in many cases it leads to a serious condition. We present a case of adnexal torsion of a mature cystic teratoma in which hemorrhagic infarction was reflected by progressive enlargement and wall thickening on successive plain abdominal radiographs. There has been no other report describing such changes of adnexal torsion on plain abdominal radiographs.

An ovary with a mature cystic teratoma which was autoamputated into the cul-de-sac and confirmed by laparoscopy is described. A 24-year-old woman with a history of chronic pelvic pain for 5 years presented with left abdominal pain. Magnetic resonance imaging revealed a left ovarian mass of 5 cm in diameter. The pain was relieved spontaneously after a few weeks. Laparoscopy was performed 5 months later. The mass was identified in the cul-de-sac partly enveloped in the omentum without any ligamentous or direct connection with the pelvic organs. There was no left ovary in its proper anatomical location. Histopathologic study revealed a mature cystic teratoma with viable ovarian tissue. These findings suggested autoamputation of the ovary either by inflammation or torsion, which is one of the mechanisms for the formation of an ectopic ovary.

A 65 year old postmenopausal female presented with left sided abdominal pain. Sonogram revealed an intra-abdominal 7.4 x 5.7 cm heterogenous mass. On laparotomy, approximately 10 X 10 cm mesenteric mass was seen adherent to the descending colon. Multiple omental tumor deposits were also noted. Gross examination showed solid and cystic tumor with sebaceous material admixed with hair. Histopathology showed mature cystic teratoma with a spectrum of well to poorly differentiated squamous cell carcinoma with omental metastasis.

Malignant transformation of ovarian dermoid cyst (mature cystic teratoma) is rare and most often established in postmenopausal women after surgery by sample anatomopathological analysis. We report the case of a 58-year-old woman showing abdominal pain associated with constipation episodes. The diagnosis of dermoid cyst was established upon ultrasonographic and tomodensitometric criteria. Its histopathological analysis confirmed the presence of a well differentiated epidermoid carcinoma. In line with the literature, our study highlights the importance of the age of the patient, the size of dermoid cyst and its growth rate as well as squamous cell carcinoma (SCC) antigen serum level. These date are collected in order to establish a correct diagnosis and provide an appropriate cure. When a cyst is discovered these data must pathological event, mostly observed in menopaused women. Certainty diagnosis is collected in order to establish a correct diagnosis and provide an appropriate cure.

The recurrence of benign sacral teratomas is a small but significant possibility. Recurrence as an endodermal sinus tumor (EST) with epidural metastases, however, has not been previously reported. The authors describe a case of a mature sacrococcygeal teratoma in a 4-day-old female patient that recurred after 22 months as an EST with epidural metastases. The child presented with abdominal pain, urinary retention, and difficulty walking. On imaging, a large pelvic mass and an epidural spinal mass were revealed. The patient's alpha-fetal protein (AFP) level was 68,000 ng/ml. Her neurological examination was significant for 3/5 plantar and dorsiflexion strength bilaterally. The patient underwent L-3, L-4, and L-5 bilateral laminectomies followed by subtotal resection of the recurrent pelvic tumor. Pathological testing of samples of both the recurrent pelvic and the extradural spinal tumors led to a diagnosis of EST. The patient underwent four cycles of chemotherapy with normalization of her AFP level to 13 ng/ml. In the weeks that followed, her AFP level steadily rose again to 167 ng/ml. Follow-up imaging revealed no tumor recurrence. The patient underwent a second course of chemotherapy followed by two tandem courses of high-dose chemotherapy with autologous stem-cell rescue. Since completing this therapy the patient has been clinically stable with an AFP level of 1.3 ng/ml for 14 months. At the 1-year follow-up examination, her plantar and dorsiflexion strength had markedly improved to 4+/5 bilaterally. To the authors' knowledge, this is the first case of a mature sacrococcygeal tumor that recurred as an EST and caused spinal canal compromise.

A 10-year-old premenarchal girl was admitted to our hospital with moderate abdominal pain, although presenting no vomiting or abdominal rebound tenderness. A large abdominal mass was visible and palpable in the periumbilical and epigastric regions. Results of physical examination revealed that the general health status was satisfactory. Computed tomographic scan revealed a large, thin-walled cyst occupying nearly the entire peritoneal cavity. The other viscera were of normal aspect. A laparoscopic approach revealed a left ovarian cystic tumor that was twisted 360 degrees in conjunction with the uterine corpus with hemorrhagic infarction. A partial hysterectomy and a left salpingo-oophorectomy were carried out. The tumor was classified as mature cystic teratoma of the ovary accompanied by hemorrhagic necrosis, not only of the cyst but also of the left uterine tube and the uterine corpus.

Ovarian torsion occurs when an ovary twists about its vascular pedicle. The process causes abdominal pain and will result in ovarian tissue loss if not diagnosed and managed expeditiously. Acute ovarian torsion is an uncommon cause of abdominal pain in adolescents, and, as a result, it is often mistaken for other processes. We present a case of ovarian torsion in an adolescent female who presented with abdominal pain and marked abdominal distension, which was initially suggestive of a gravid abdomen. She was ultimately found to have a very large cystic teratoma of the right ovary with concomitant ovarian torsion. There are no reported cases of ovarian cystic teratoma with acute torsion presenting with an abdominal mass suggestive of a gravid abdomen.

Immature teratomas represent only the 1% of ovarian teratomas, and they are the third most common primitive germ cell tumor; generally, they are congenital lesions and affect mainly the first 2 decades. We present the case of a 7-year-old child who came at our attention because of an acute low abdominal pain due to the torsion of an ovarian immature grade 1 teratoma on its pedicle. After ultrasound in the emergency department, preoperative evaluation was done by performing a magnetic resonance study, whose findings helped in suggesting the curative approach. The magnetic resonance imaging characteristics of the neoplasm are reviewed and correlated with histopathologic findings. As it was highlighted in our case, magnetic resonance imaging may be part of the diagnostic approach of this rare disease entity also in a small child in emergency.

Benign solid teratomas within the fallopian tube are rare. The incidence of this kind of benign solid teratoma of the fallopian tube associated with intrauterine leiomyomas is extremely low and may complicate the clinical manifestations. Here, we report a 40-year-old female with periodic lower abdominal pain and hypermenorrhea who was found to have 3 nodules within the uterine myometrium and left distended fallopian tube. Final pathology revealed benign solid teratoma of the fallopian tube associated with 3 intrauterine leiomyomas. Primary teratoma of the fallopian tube is extremely uncommon. Gynecologic oncologists should be aware of the possibility of this disease entity when making differential diagnoses.

Ovarian torsion is defined as partial or complete rotation of the ovarian vascular pedicle and causes obstruction to venous outflow and arterial inflow. Ovarian torsion is usually associated with a cyst or tumor, which is typically benign; the most common is mature cystic teratoma. Ultrasonography (US) is the primary imaging modality for evaluation of ovarian torsion. US features of ovarian torsion include a unilateral enlarged ovary, uniform peripheral cystic structures, a coexistent mass within the affected ovary, free pelvic fluid, lack of arterial or venous flow, and a twisted vascular pedicle. The presence of flow at color Doppler imaging does not allow exclusion of torsion but instead suggests that the ovary may be viable, especially if flow is present centrally. Absence of flow in the twisted vascular pedicle may indicate that the ovary is not viable. The role of computed tomography (CT) has expanded, and it is increasingly used in evaluation of abdominal pain. Common CT features of ovarian torsion include an enlarged ovary, uterine deviation to the twisted side, smooth wall thickening of the twisted adnexal cystic mass, fallopian tube thickening, peripheral cystic structures, and ascites. Understanding the imaging appearance of ovarian torsion will lead to conservative, ovary-sparing treatment.
