• Article: Cystic partially differentiated nephroblastoma.

  M Puvaneswary, J Macintosh, J Cassey
  [show abstract] [hide abstract]
  ABSTRACT: Cystic partially differentiated nephroblastoma is a relatively rare tumour of the kidney usually affecting infants. Cystic Wilms' tumour and multilocular cystic nephroma should be distinguished from cystic partially differentiated nephroblastoma. Multilocular cystic nephroma is a benign tumour whereas cystic Wilms' tumour is at the malignant end of the range of classification of such tumours. Cystic partially differentiated nephroblastoma may undergo local recurrence but there is no report of metastasis.

• Article: Pelvic anatomy and MRI.

  S Paramasivam, A Proietto, M Puvaneswary
  [show abstract] [hide abstract]
  ABSTRACT: An in-depth knowledge of the anatomy of the pelvis and pelvic sidewall is necessary before a gynaecologist can even contemplate making an initial examination and start management in cases of pelvic pathology or malignancy. This chapter provides basic information on gross pelvic anatomy structures that are of clinical relevance and discusses their correlation with medical imaging, especially magnetic resonance imaging (MRI). MRI is an ideal non-invasive technique in the assessment of normal anatomy and tissue characterization of pelvic pathology. The excellent soft-tissue contrast and the ability to direct multiplanar imaging and to demonstrate blood vessels without the use of intravenous contrast make MRI superior to other imaging modalities in the evaluation of pelvic abnormalities. The anatomical relation of the visceral organs, the differential zonal anatomy of the corpus uteri and the cyclical endometrial changes during the menstrual cycle are well depicted with MRI.

• Article: Mucocele of the appendix with magnetic resonance imaging findings.

  M Puvaneswary, A Proietto
  [show abstract] [hide abstract]
  ABSTRACT: Mucocele of the appendix is a rare lesion caused by abnormal accumulation of mucus. Although preoperative diagnosis is important to avoid rupture of a mucocele, the diagnosis is often made at surgery. We report a case of an appendiceal mucocele that mimicked a hydrosalpinx on CT and MRI.

• Article: Double-chambered right ventricle: magnetic resonance imaging findings.

  M Puvaneswary, N Indira, M Sreedhar, B Barooah
  [show abstract] [hide abstract]
  ABSTRACT: Primary double-chambered right ventricle is an uncommon congenital anomaly that presents with right ventricular outflow tract obstruction in childhood or adolescence. A search of the literature revealed only a few documented case reports with MRI findings. We present a case with mixed lesions, and with anomalous muscle bundles located both in the middle portion of the right ventricular sinus and at the subinfundibular level.

• Article: Primary papillary serous carcinoma of the peritoneum: four cases and review of computed tomography findings.

  M Puvaneswary, T Proietto
  [show abstract] [hide abstract]
  ABSTRACT: Primary papillary serous carcinoma of the peritoneum is an uncommon primary malignancy of the peritoneum and is histologically indistinguishable from papillary serous carcinoma of the ovary. The diagnosis of primary peritoneal papillary serous carcinoma should be considered in the presence of peritoneal and omental masses in the absence of an ovarian mass. Although it has been extensively documented in the pathological and gynaecological oncology literature, the CT appearance of primary papillary serous carcinoma of the peritoneum has been reported in only 51 cases in five reports. We present four patients with CT findings of pathologically proven primary papillary serous carcinoma of the peritoneum. There were a total of 23 patients with a histopathologically proven diagnosis of primary papillary serous carcinoma of the peritoneum between 1980 and 2002 with CT imaging. However, only four of the 23 patients' CT films were retrieved for retrospective evaluation. The rest of the films were not available as either patients had misplaced the films or patients were deceased.

  ABSTRACT: We report a case of duodenal malrotation that presented in adulthood as midgut volvulus. On colour Doppler ultrasound, findings of a clockwise rotation of the superior mesenteric vein around the superior mesenteric artery (whirlpool sign) and a distinctive 'whirl'-like pattern resulting from an encircling of loops of the bowel around the SMA on CT is diagnostic of midgut volvulus.

  ABSTRACT: Pulmonary arteriovenous malformations (AVMs) are rare vascular malformations of the lung. Although most patients are asymptomatic, AVMs can bleed and result in haemoptysis and haemothorax. We describes a case of pulmonary AVMs in a patient with Osler-Weber-Rendu syndrome with 3-D contrast-enhanced MR angiography. Magnetic resonance angiography provided accurately and non-invasively the number and size of the feeding arteries and draining veins.

  ABSTRACT: Significant eosinophilia and even eosinophilic tissue infiltration has been associated with a variety of clinical disorders including allergic and immunodeficiency states, drug reaction, infection, parasitic infestation and malignancy. Eosinophilia without an underlying aetiology and with multi-organ dysfunction has been designated idiopathic hypereosinophilic syndrome. We report a case of endomyocardial fibrosis with MRI findings.

  ABSTRACT: Congenital mesoblastic nephroma (CMN) is a rare renal tumour usually imaged by ultrasound and or CT. To the authors' knowledge there have been only two previous reports concerning MR imaging of CMN in the English-speaking literature. The MRI findings in a neonate with CMN, which were not previously described, are reported here.
