Non contrast-enhanced four-detector multisection CT for the detection of ring lesions in seizures.

AIM: To evaluate the role of non contrast-enhanced multidetector computed tomography (MDCT) in the detection of ring lesions in the brain in patients from the Indian subcontinent, presenting with seizures. MATERIALS AND METHODS: Ninety-four patients presenting with seizures were examined using four-detector MDCT. Contiguous axial non contrast-enhanced CT of the brain was performed with a section width/section collimation of 5mm/5mm. A single axial non-contrast enhanced examinaton of section width 2.5mm was obtained through the region of interest, if necessary. This was followed by contrast-enhanced sequential imaging in all patients, using the same parameters as for unenhanced CT (i.e., 5mm/5mm). Non-contrast and contrast-enhanced CT images were recorded and reviewed separately. RESULTS: In 63 out of 94 cases non-enhanced MDCT (with section width 5mm) was able to identify the ring lesions. In 11 cases, which were doubtful on unenhanced CT (5mm), performing a single examination using a section width of 2.5mm through the area of interest, helped to detect the ring lesion. Hence in 74 out of 94 (79%) cases ring lesions could be detected using unenhanced MDCT. In the remaining 21% cases, the presence of ring lesions in the brain was confirmed only after the intravenous administration of contrast medium. CONCLUSION: Non contrast-enhanced MDCT is recommended for detecting ring lesions in the brain of patients on the Indian subcontinent, presenting with seizures. This can help to decrease the radiation dose to the patient and reduce the duration of examination. The risk of adverse reactions and patient discomfort associated with intravenous contrast medium injection are also reduced as are the costs incurred. Contrast-enhanced MDCT should be performed only in those cases in which the presence of ring lesions is doubtful on unenhanced CT.

Filarial dance in a breast mass on colour Doppler imaging.

Filarial dance in breast lesions is a very rare entity. It is difficult to show the characteristic vigorous movement of the adult worms on static images although pulse wave Doppler and colour power Doppler have been used. Filarial dance on colour Doppler imaging has not been reported earlier to the best of our knowledge.

Diagnosis of tubular colonic duplication by barium follow-through study.

Barium enema studies are considered essential for the diagnosis of tubular colonic duplication with opacification of two colons being the diagnostic sign. Yet in certain cases, barium enema apparently does not show positive findings. A case is reported in which a barium follow-through study established the complete diagnosis of duplication of colon and terminal ileum. The findings were confirmed on laparotomy.

Management of traumatic cataract in children.

PURPOSE: To evaluate the presentation, mode of management, and clinical outcome of traumatic cataract in children. SETTING: L.V. Prasad Eye Institute, Hyderabad, India. METHODS: One hundred thirty-seven children (< 16 years) who developed traumatic cataract, seen between January 1988 and December 1993, were retrospectively analyzed. Nature of injury, type of cataract, management, and outcome were evaluated. RESULTS: The study group comprised 110 boys and 27 girls. Average follow-up was 11.7 months (range 1 week to 60 months). Most injuries (54.7%) were caused by a stick or a bow and arrow. Most (53.2%) of the cataracts were total. Corneal scarring (60.5%) and iris-related problems (49.6%) were the most common associated findings. Extracapsular cataract extraction with intraocular lens (IOL) implantation was performed in 65.67% of patients. Visual acuity improved form 20/200 or worse in 97.7% of patients preoperatively to 20/60 or better in 74.1% or patients postoperatively. Seventeen patients had associated posterior segment insult; most failed to recover satisfactory vision. Posterior capsule opacification (PCO) was noted in 42.9% of patients. CONCLUSIONS: Extracapsular cataract extraction with IOL implantation provides satisfactory results in children with traumatic cataract. Associated posterior segment complications and development of PCO are the major obstacles to visual rehabilitation.

Globe rupture during digital massage after peribulbar anesthesia.

A 75-year-old woman developed globe rupture with extrusion of intraocular contents during digital massage after periocular injection of an anesthetic. The rupture was repaired. At the last follow-up 6 months after surgery, visual acuity was 20/160. The retina was attached, and the vitreous hemorrhage was resolving. This complication of peribulbar anesthesia and digital massage highlights the importance of using quantitative techniques to induce hypotony during peribulbar anesthesia.

Co-occurring adenoviral keratitis and hemorrhagic cystitis. A case report.

Adenoviruses are ubiquitous viruses, commonly causing ocular infections. They are also known to cause multisystem infections. External ocular infections caused by adenovirus are most often due to contaminated secretions. We report a patient in whom genitourinary symptoms developed and subsided along with ocular symptoms. Adenovirus was isolated on ocular culture. This is the first reported case of concurrent adenoviral keratitis and hemorrhagic cystitis. Eliciting a history of genitourinary and respiratory symptoms is important in patients with ocular adenoviral infections.
