A rare case of atypical skull base meningioma with perineural spread by Henry Walton et al. |
Published: 2015 Dec Issue: 9(12) :: Pages: 1-14
| Abstract: Atypical meningioma is a rare cause of perineural tumour spread. In this report, we present the case of a 46-year-old female with an atypical meningioma of the skull base demonstrating perineural tumour spread. We describe the imaging features of this condition and its distinguishing features from other tumours exhibiting perineural spread.

A Torted Ruptured Intra-abdominal Testicular Seminoma Presenting As An Acute Abdomen by Oliver James Nickalls et al. |
Published: 2015 Dec Issue: 9(12) :: Pages: 21-28
| Abstract: The susceptibility of the undescended testis to malignant transformation is well documented. The most common location of the undescended testis is within the inguinal canal, with only a minority located within the abdominal cavity. When a testicular mass develops, the risk of torsion increases. We describe a large intra-abdominal testicular seminoma that had undergone torsion, rupture and haemorrhage, presenting as an acute abdomen. A 30 year old man presented to the emergency department with right iliac fossa pain. Computed tomography in the emergency department showed haemoperitoneum and a torted large left testicular mass, likely malignant. The patient underwent laparotomy and excision of the mass. Histologic examination revealed a grossly enlarged seminomatous testis which had torted and ruptured. While pre-operative imaging diagnosis of an intra-abdominal testicular seminoma has been published, reports are few. To the best of the author`s knowledge pre-operative imaging diagnosis of a malignant testicular mass with torsion and intra-abdominal haemorrhage presenting as an acute abdomen has not been described before.

Isolated Fallopian Tube Torsion With Fimbrial Cyst In A 10 Year-old Girl Diagnosed By Ultrasound: A Case Report by Maria Constancia Olveda Ormasa et al. |
Published: 2015 Dec Issue: 9(12) :: Pages: 29-36
| Abstract: Torsion of the fallopian tube without the involvement of the ipsilateral ovary is a rare but important cause of acute abdominal pain in women as it is a surgical emergency. Although uncommon, it should be considered as one of the differential diagnosis in female children presenting with acute lower abdominal or pelvic pain. The diagnosis of isolated fallopian tube torsion is difficult pre-operatively and is often made during laparoscopic or surgical exploration because diagnostic features are usually non-specific. In this report, we present a case of isolated fallopian tube torsion with fimbrial cyst in a young female patient diagnosed pre-operatively by ultrasound.

Inferior vena cava filter penetration following Whipple surgical procedure causing ureteral injury by Ahmed Kamel Abdel-Aal et al. |
Published: 2015 Dec Issue: 9(12) :: Pages: 37-43
| Abstract: We report a case of an indwelling inferior vena cava filter that penetrated the IVC wall after Whipple`s pancreatico-duodenectomy procedure performed in a patient with ampullary carcinoma, resulting in right ureteral injury and obstruction with subsequent hydroureter and hydronephrosis. This was incidentally discovered on a computed tomography scan performed as routine follow up to evaluate the results of the surgery. We retrieved the inferior vena cava filter and placed a nephrostomy catheter to relieve the ureteral obstruction. Our case highlights the importance of careful inferior vena cava manipulation during abdominal surgery in the presence of an inferior vena cava filter, and the option of temporary removal of the filter to be placed again after surgery in order to avoid this complication, unless protection is required against clot migration during the surgical procedure.

Incidentally Discovered Middle Mesenteric Artery In A Renal Donor by Ahmed Kamel Abdel-Aal et al. |
Published: 2015 Dec Issue: 9(12) :: Pages: 15-20
| Abstract: The middle mesenteric artery is a very rare anomalous artery originating from the ventral surface of the abdominal aorta in-between the superior mesenteric artery and inferior mesenteric artery. We identified a middle mesenteric artery during abdominal computed tomographic angiography in a renal donor patient as a part of his work up. The middle mesenteric artery branched out into ileal and ileocolic arteries, supplying the terminal ileal loops as well as the cecum. The anomalous artery had no effect on patient`s eligibility as a renal donor candidate.
