Abstract

Introduction: Rhabdomyosarcoma (RMS) is a rare soft tissue tumor, mainly affecting children, adolescents, and adults younger than 15 years, representing 3% to 4% of all childhood malignancies. Genitourinary is the second-most-common location of RMS with around 25% of cases. We describe a rare case of vaginal rhabdomyosarcoma in adolescents with huge polypoid tumors. Case Presentation: A 15-year-old female presented with vaginal bleeding for seven months. Her medical story was unremarkable. The clinical examination showed a polypoid mass prolapsed from the vagina, and the laboratory result was anemia. The pelvic magnetic resonance imaging (MRI) showed a heterogenous bulky solid tumor in the vagina. The histopathological finding revealed a sarcoma, and the immunohistochemical staining result was rhabdomyosarcoma not otherwise specified (NOS). Conclusions: Vaginal RMS is a rare malignant tumor of mesenchymal origin with skeletal muscle differentiation. Vaginal RMS is the most common site of genitourinary RMS and presents as a rapidly growing and aggressive local mass. Imaging plays an important role in the initial diagnosis of vaginal RMS, regarding the presentation of the bulky protruding tumor on the vaginal region

Abstract

Spinal cord injury is a common type of injury that can be highly fatal. Clinically, spinal cord injury can be assessed using standardized physical examination scoring from International Standards for Neurological and Functional Classification of Spinal Cord Injury Patients, which is the American Spinal Injury Association (ASIA) impairment scale or often called as AIS. The results of this scoring will then be combined with magnetic resonance imaging (MRI) examination to determine the diagnosis and prognosis. In this case, we report a 20-year-old male complaining weakness in four extremities after traffic accident while driving a motorcycle. Based on neurological examination, the patient can barely feel a touch sensation and cannot move both his arms and legs at all. Cervical X-ray examination showed dislocation fracture on C5 level. Further MRI examination showed edema and spinal cord hemorrhage around fracture area. The findings of edema and spinal cord hemorrhage on MRI examination are useful in diagnosing and predicting the outcome of patient with spinal cord injury.

Abstract

Pendahuluan: Kehamilan ektopik (KE) adalah kehamilan dengan letak implantasi di luar kavum uterus. Diagnosis KE ditegakkan melalui tes urin, ultrasonografi, penilaian level β-hCG, dan kuretase. Ultrasonografi transvaginal adalah modalitas imejing terpilih, meskipun pada beberapa kondisi, sulit menentukan antara kehamilan awal atau KE melalui Ultrasonografi transvaginal. Pada KE dapat terjadi juga beberapa gambaran kelainan di intra-uterus/endometrium. Kasus: Seorang wanita 32 tahun dengan riwayat kehamilan ektopik 2 kali sebelum dan sekarang dengan periode menstruasi terlambat 2 bulan. Tes kehamilan positif dengan kadar β-hCG 24,411 mIU/ml. Pasien menjalani TVU dan dicurigai adanya massa intra uterin tanpa ditemukan struktur kantung gestasi (GS). Pasien diduga menderita gestational trophoblastic disease (GTD) karena pada pemeriksaan laboratorium didapatkan hasil tes kehamilan positif dan peningkatan kadar β-hCG, dan USG tidak menunjukkan adanya GS intra/ekstra kavum uteri. Pasien menjalani MR pelvis dengan hasil dicurigai adanya kantung kehamilan di adneksa kiri dan menunjukkan perubahan endometrium yang menyerupai lesi massa. Pasien menjalani operasi laparotomi dan mengungkapkan kehamilan ektopik di dalam tuba Fallopi kiri dengan hemoperitoneum masif, diagnosis ini dikonfirmasi pada hasil patologis. Simpulan: Apabila sulit menegakkan diagnosis dengan ultrasonografi transvaginal, maka modalitas MRI menjadi pilihan karena memiliki kemampuan diagnosis yang lebih baik. Pengetahuan akan gambaran klinis dan MRI pada KE sangat penting untuk menentukan diagnosis yang akurat dan penatalaksanaan yang tepat.

Abstract

BACKGROUND Diffusion-weighted magnetic resonance imaging (DW-MRI) is a noninvasive, non-contrast sequence for cancer detection. Research involving DW-MRI in cervical cancer has revealed lower apparent diffusion coefficient (ADC) values. This study aimed to evaluate the difference in tumor ADC values and ADC ratios (tumor-to-urine and tumor-to-muscle) with respect to tumor staging (early versus late) and histopathology (squamous cell carcinoma versus adenocarcinoma). METHODS This retrospective study included 56 patients with cervical cancer, divided into early- and late-stage groups. DW-MRI was performed in all patients, and the tumor ADC value, ADC ratio between the tumor and urine (ADC ratiot−u), and ADC ratio between the tumor and gluteal muscle (ADC ratiot−m) were measured. Statistical methods were employed to assess the difference in the tumor ADC value, ADC ratiot−u, and ADC ratiot−m with respect to cervical cancer stages and histopathological findings. RESULTS The median tumor ADC value was lower in the early-stage group than in the late-stage cervical cancer (0.75 × 10−3 mm²/s versus 0.8 × 10−3 mm²/s, p = 0.022). However, no differences were observed in ADC ratiot−u and ADC ratiot−m concerning the tumor staging, nor in ADC value, ADC ratiot−u, and ADC ratiot−m concerning histopathological findings (p = 0.29, 0.67 and 0.35, respectively), with no significant differences in the ADC ratiot−u (p = 0.153) and ADC ratiot−m (p = 0.260). In receiver operating characteristic analysis, the tumor ADC value was 75.0% sensitive and 50.0% specific in predicting late-stage cervical cancer with a cut-off value of 0.750 × 10−3 mm2/s. CONCLUSIONS The median tumor ADC value in early-stage patients was significantly lower than in the late-stage patients, suggesting that tumor ADC value has valuable potential for characterizing cervical cancer staging.
