AB  - AIM: To investigate typical features of primary fallopian tube carcinoma (PFTC) 
      on magnetic resonance imaging (MRI) to differentiate it from epithelial ovarian 
      cancer (EOC). MATERIALS AND METHODS: Twenty-one patients with PFTC and 35 
      patients with EOC were included. The clinical and pathological features of 
      patients were analysed. The following MRI features were compared: maximal 
      diameter, laterality, configuration, shape, signal intensity, enhancement 
      pattern, hydrosalpinx, intrauterine fluid accumulation, rim enhancement, and 
      apparent diffusion coefficient (ADC) values within the solid components of 
      tumours in PFTC and EOC. RESULTS: The maximal diameter of PFTC was 4.50+/-2.10 cm. 
      The shapes of PFTC were mural papillary nodules (2/21, 10%), sausage-like (8/21, 
      38%), nodular (3/21, 14%), or irregular (8/21, 38%). Enhancement was mild (10/21, 
      48%), moderate (8/21, 38%), or marked (3/21, 14%). Associated hydrosalpinx and 
      intrauterine fluid accumulation were observed in six (29%) and three (10%) cases, 
      respectively. Significant differences between PFTC and EOC were found in the 
      International Federation of Gynecology and Obstetrics (FIGO) stage, maximal 
      diameter, shape, enhancement pattern, hydrosalpinx, and intrauterine fluid 
      accumulation (p=0.002, 0.004<0.001, <0.001, and 0.048, respectively). Rim 
      enhancement was more prevalent, thicker, and exhibited higher continuity in PFTC 
      than in EOC (p=0.002, <0.001, and 0.002, respectively). CONCLUSIONS: Rim 
      enhancement is a useful feature in distinguishing PFTC from EOC, particularly 
      when continuous or seen in combination with a sausage-like shape, hydrosalpinx or 
      intrauterine fluid accumulation. When the tumour is associated with other MRI 
      signs, for example, (i) hydrosalpinx with mural papillary nodules or sausage-like 
      shape with mild-to-moderate enhancement of solid components, (ii) hydrosalpinx, 
      or (iii) intrauterine fluid accumulation, the diagnosis of PFTC should be 
      considered.
