Abdominal And Pelvic Pain

Sonography is the primary imaging modality for the evaluation of pelvic pain in female patients, especially if gynaecological pathology is suspected. However, computed tomography (CT) is frequently used in patients who present to emergency departments (and elsewhere) with otherwise nonspecific abdominal and pelvic pain and may be the first imaging modality to demonstrate an acute gynaecological abnormality. Computed tomography can also be used prospectively in selected patients to further evaluate findings initially identified on sonography, although to reduce radiation exposure, magnetic resonance imaging is being used more frequently in this situation. The purpose of this article is to discuss the spectrum of gynaecological findings of the acute female pelvis that may be identified on CT by the emergency radiologist and by the general radiologist, with a brief review of the imaging literature of each specific diagnosis.

ABSTRACT: Arachnoid cysts are accumulations of cerebrospinal fluid that occur within the arachnoid membrane due to the splitting or duplication of this structure. The aim of this retrospective study is to report the occurrence of this condition in 26 dogs, as well as to describe the findings of computed tomography imaging and magnetic resonance image scans and to correlate these with the clinical signs. A prevalence of the condition was observed in males, predominantly in the small breeds Miniature Pinscher and Shih Tzu, with age raging from 2 months to 9 years. The mainly clinical signs observed in these dogs were seizures and cerebellar ataxia. The study concluded that in 17 dogs the quadrigeminal arachnoid cyst was regarded as an incidental finding, in 6 dogs this condition was regarded as the determinant cause of the clinical signs, and in 3 dogs some clinical signs were associated with arachnoid cyst, but they also presented clinical signs involving others sites of intracranial lesion.

Background Venous malformation (VM) is a common vascular malformation in soft tissue. Surgical management plays an important role in its treatment. The location, extent, and adjacent anatomy of the lesion are crucial information for the safety of operation. This study introduces the application of magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging in gathering above information. Methods A retrospective analysis was made in the patients with venous malformation from January 2012 to June 2014 in our clinic. All patients underwent magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging. The location, extent of the lesion, its draining veins, and the relationship with around tissues were showed. Surgical management was carried out in the lesions which were well defined, located in the superficial fascia without important vessels and nerves across it. The wound was repaired by skin flap or skin graft. Results A total of 13 patients underwent complete surgical removal of the lesions, including five type I venous malformations and eight type II venous malformations. Ten lesions were removed by undermining dissection, and the wound was repaired by the undermined flap. Three superficial lesions were removed together with the skin over it, and the wound was repaired by the skin graft. In the six months to two years of follow-up period, none of the recurrence of the lesion was observed. Conclusion Magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging can display abundant morphological details of venous malformation, which are helpful for the surgical management.

Isolated primary sphenoid sinusitis is a rare occurrence, estimated to make up less than 3% of sinus infections. The posterior anatomic location of the sphenoid makes treatment challenging when it becomes infected. Complications involving intracranial extension to surrounding structures often result in cranial nerve deficits due to their proximity. A single case of chronic sphenoiditis with direct extracranial extension into the prevertebral space is reported with a discussion on clinical presentation, diagnosis, and management. A 46-year-old female patient with diffuse headaches radiating into the neck and throat was evaluated in the office. Computed tomography demonstrated sphenoiditis with direct extension into the prevertebral space. Imaging revealed a purported route of direct extension through the clinoid and directly into the clivus to form an abscess in the longus colli muscle. The patient underwent endoscopic surgical management including drainage of the prevertebral abscess and has since made a full recovery. This is the first reported case of direct extension of sphenoiditis into the prevertebral space. The findings highlight the importance of aggressive treatment of chronic sphenoid infections to prevent detrimental complications. Computed tomography imaging proved an advantageous imaging modality to demonstrate bony erosion and sinus tracts from the skull base to the deep neck space.
