Assessment of Lower Segment Ceasarean Scar by Transvaginal Ultrasound and MRI

Objective: To assess lower segment scar on ultrasound and MRI followed by comparing with the intraoperative findings of scar in lower uterine segment. Methods: This was a prospective observational comparative study with a sample size of 40. Patients were recruited from the antenatal clinic. The study included women with previous one lower segment cesarean section and not willing for trial of labour after birth and those with previous one lower segment cesarean with no H/O previous vaginal birth. Routine obstetric examination was done at 36-37 weeks POG. A detailed obstetric ultrasound was performed. Patients before undergoing elective repeat lower segment cesarean section had Transvaginal ultrasonography (TVS) and MRI for evaluation of previous cesarean uterine scar. Result: The mean age of study group was 29.28 ± 3.48 yrs. The mean scar thickness in study group on TVS was 3.36 mm ± 1.2 mm. Mean scar thickness on MRI was 3.5 mm± 1.12mm. During intra-operative assessments of scar, in 82.5% cases scar was intact while in 15% cases scar was dehiscent. There was a positive correlation between all three modalities i.e. TVS , MRI and intra-operative findings. Conclusion: In this observational comparative done to correlate scar thickness measured on TVS and MRI with the intra-operative scar thickness, based on the findings we conclude that both TVS and MRI can be used for measurement of scar thickness.

Intralesional radiofrequency ablation for nodular angiolymphoid hyperplasia on forehead: A minimally invasive approach.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is an idiopathic acquired condition characterized by erythematous papulo-nodular lesions with a predilection for the head and neck. The lesions are cosmetically disfiguring, resistant to most medical and surgical therapies and tend to recur. We report the novel use of radiofrequency equipment in the management of nodular ALHE on forehead of a 53-year-old man. Intra-lesional radiofrequency ablation was done using a modified 18 gauge intravenous cannula and three sittings over a period of four years yielded cosmetically acceptable results with no recurrence and minimal side effects.

Extensive disseminated cysticercosis.

Cysticercosis, especially neurocysticercosis, is a major public health problem in India. We report an unusual case of disseminated cysticercosis with extensive infi ltration of the skin, central nervous system, skeletal muscles, eye, lung, and heart. A patient with extensive cutaneous cysticercosis must be thoroughly investigated for widespread internal organ involvement.

Nephrogenic systemic fibrosis: A review of the new conundrum.

Nephrogenic systemic fibrosis is an idiopathic, sclerosing condition that occurs only in patients who have impaired renal function. Although its most conspicuous manifestation is in the skin, the condition involves multiple organ systems and is potentially fatal. Its postulated association with gadolinium-based magnetic resonance contrast agents has attracted attention. The distinctive clinical features of this entity include a prodromal systemic inflammatory syndrome followed by a chronic course of fibrosis that has a predilection for the skin and subcutaneous tissues of the extremities. The progressive systemic fibrosing process involves multiple organs and contributes to the morbidity and the increased mortality. Appropriate preventive action, prompt recognition and timely reporting of cases may enable better management of this condition.

Imaging spectrum of pediatric orbital pathology: a pictorial review.

A wide spectrum of pediatric orbital disorders can occur in the pediatric age group. Cross-sectional imaging plays an important role in the diagnosis and management of these patients. We reviewed our imaging record and collected representative cases of pediatric orbital pathology. The purpose of this pictorial essay is to illustrate the imaging features of various orbital lesions encountered in children.

Hepatic hydatid cysts with biliary, and peritoneal rupture and transdiaphragmatic migration.

Hydatid disease is a parasitic infection that most commonly involves the liver. Imaging plays a vital role in the diagnosis of this disease. Rupture of the cyst can give rise to a wide spectrum of complications. We describe a case of hepatic hydatid cyst with rupture into the biliary tree, right pleural cavity and dissemination into the peritoneal cavity, with associated splenic hydatid cysts. MRI may be a useful non-invasive diagnostic tool in such disseminated cases to define the complete extent of the disease.

Pre-operative diagnosis of Meckel's diverticulum: report of a case and review of literature.

Meckel's diverticulum represents a patent omphalomesenteric duct at its junction with the ileum. Although it is a common anomaly, it is often a surgical surprise as the preoperative diagnosis is seldom established. We present an unusual case where the constellation of imaging findings was so typical that we could suggest this diagnosis prospectively and it was subsequently confirmed surgically.

Role of MR imaging in pediatric surgery.

Magnetic Resonance Imaging is a non-invasive multiplanar imaging modality which does not use ionizing radiation. In recent years major technical advances in this field have led to shorter imaging times and better resolution. This has widened the scope of this modality in pediatric imaging. MRI is already an established technique for the brain and spine and is increasingly being used for musculoskeletal, abdominal and pelvic imaging. In this article the authors provide an update on this exciting modality with stress on applications relevant to pediatric surgeons.
