Abstract
OBJECTIVES To examine the association between ovarian immobility and presence of endometriomas and assess the diagnostic accuracy of transvaginal sonographic (TVS) ovarian immobility in the detection of deep infiltrating endometriosis (DIE). METHODS This was a multicenter prospective observational study of women presenting with chronic pelvic pain from January 2009 to March 2015. Women with or without history of endometriosis who were scheduled to undergo laparoscopic surgery for endometriosis gave a detailed history and underwent specialized TVS in a tertiary referral unit prior to laparoscopy. During TVS, ovarian mobility and the presence of endometriomas were assessed. The relationship between TVS ovarian mobility, with or without endometriomas, and DIE was correlated with the gold standard, diagnosis of endometriosis at laparoscopy. RESULTS Included in the analysis were 265 women with preoperative TVS and laparoscopic outcomes. Ovarian immobility on TVS was significantly associated with presence of endometriomas at surgery, with a prevalence of 12.2%, 10.8% and 52.7% for fixation of the left ovary only, the right ovary only and bilateral ovaries, respectively, compared with 4.2%, 3.7% and 7.3% for normal ovaries. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and positive and negative likelihood ratios of TVS ovarian immobility for diagnosis at surgery of immobility of ovaries with endometriomas in the left ovary only were 44.4%, 92.3%, 44.4%, 92.3%, 5.8, 0.6, in the right ovary only were 50.0%, 98.5%, 80.0%, 94.2%, 33.0, 0.5 and bilaterally were 74.4%, 68.6%, 72.5%, 70.6%, 2.4, 0.4, while those for diagnosis of immobility of normal ovaries were 25.0%, 87.9%, 8.3%, 96.4%, 2.1, 0.9 for left ovary only, 14.3%, 92.9%, 7.1%, 96.6%, 2.0, 0.9 for right ovary only and 35.7%, 97.2%, 50.0%, 95.0%, 12.6, 0.7 bilaterally, respectively (P < 0.05 except for normal left and right ovaries with P = 0.2 and 0.4, respectively). The sensitivity, specificity, PPV and NPV for performance of ovarian immobility in the prediction of DIE for all women were 58.3%, 74.1%, 60.6%, 72.2% and in the prediction of need for bowel surgery were 78.2%, 71.1%, 41.3%, 92.6%, respectively. CONCLUSIONS There is a significant association between ovarian immobility and the presence of endometriomas. Ovarian immobility as a sonographic 'soft marker' of DIE performs better in the presence of endometriomas compared with in normal ovaries. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Background Craniopharyngiomas are rare intracranial tumors commonly presenting with neurological symptoms. Reports of severe hyponatremia as a presenting manifestation of a craniopharyngioma and hyponatremia-induced myopathy are rare. We report the case of a patient with craniopharyngioma presenting with severe hyponatremia, panhypopituitarism, and hyponatremia-induced myopathy. Case presentation A 52-year-old Sri Lankan man presented with anorexia, nausea, fatigue, generalized muscle weakness, and cramps for 1 week. The onset of his illness had been preceded by vomiting and diarrhea for 1 day which he attributed to food poisoning. On examination, he had an apathetic disposition with a generalized “sallow complexion.” He was not dehydrated. Apart from reduced muscle power (4/5) and hyporeflexia, the neurological examination was normal. His serum sodium was 102 mmol/l; potassium 4.1 mmol/l; chloride 63 mmol/l; plasma osmolality 272 mosm/KgH2O; urine osmolality 642 mosm/KgH2O; and urine sodium 79 mmol/l. His creatine phosphokinase was 12,400 U/l, lactate dehydrogenase 628 U/l, aspartate aminotransferase 360 U/l, and alanine aminotransferase 64 U/l. His hormone profile revealed panhypopituitarism. An electromyogram showed nonspecific abnormalities while a muscle biopsy did not show any pathology. Magnetic resonance imaging of his brain demonstrated a well-defined craniopharyngioma with suprasellar extension. His pituitary gland was compressed and the pituitary stalk was displaced by the tumor. He had marked improvement in muscle power and rapid reduction of serum creatine phosphokinase levels paralleling the correction of severe hyponatremia, even before the initiation of hormone replacement. Conclusions This case illustrates the rare presentation of severe hyponatremia and hyponatremia-induced myopathy in patients with craniopharyngioma, awareness of which would facilitate early appropriate investigations and treatment.

Abstract
The distribution of Lipiodol in the liver and lungs following arterial or portal injection was studied in normal (n = 55) and cirrhotic rats (n = 20). Using magnified xeroradiography and radioisotope labeled tracers, it was found that Lipiodol was deposited mainly in the liver and lung after either arterial or portal administration. In control rats after arterial injection, deposits in the lung peaked after 2 hours and gradually declined over 48 hours; whereas after portal injection, the deposit steadily increased for 48 hours. Twenty-five percent of cirrhotic rats demonstrated a Lipiodol-induced miliary pattern in the lung. An increased number of portosystemic shunts in cirrhotic rats was also noted. These results suggest that cirrhosis of the liver may be a potential risk factor for developing pulmonary complications after Lipiodol administration.
