Changes in the globus pallidus in chronic kernicterus
The objective of the study was to establish the diagnosis of kernicterus as a cause of seizures and abnormal movements in a 1-year-old child. We performed an MRI of the brain of the child on our 1.5 T scanner. The MRI of the patient showed high signals on T2-weighted images in the globus pallidus bilaterally, with no evidence of mass effect. Because of an increased risk of hearing loss, the brain-stem evoked response examination was also performed. The brain-stem evoked response examination showed bilateral severe sensorineural hearing loss. The presence of isolated hyperintense signals in basal ganglia (globus pallidi) was very useful in the evaluation of the structural changes in posticteric bilirubin encephalopathy
Diagnostic role of magnetic resonance angiography in Swyer James syndrome: Case series of two cases
Swyer James syndrome is a rare syndrome which occurs due to viral illness in early childhood. The post infective obliterative bronchiolitis results in arrest of lung growth and alveolarization with reduced vascularity resulting in classical radiological features. We describe two cases of patients fulfilling all the criteria of the syndrome - 1) Unilateral hyperlucent small lung in chest radiograph with air trapping on expiration, small ipsilateral hila and pulmonary artery. 2) Diffuse decrease in attenuation of lung parenchyma with bronchiectasis and reduction in vascularity. 3) Unilateral pruned tree appearance on angiography (MRA). The clinical presentation was recurrent chest infection in a child and infrequent bouts of hemoptysis in a middle aged female. The study demonstrates the role of magnetic resonance angiography in diagnosing the condition
A new classification of inferior vena cava thrombus in renal cell carcinoma could define the need for cardiopulmonary or venovenous bypass
Introduction: Although the level of inferior vena cava (IVC) thrombus governs the type of surgical approach, there is no consistency in reporting the levels of IVC thrombus in the literature. This prospective study illustrates a simple three-level classification based on the need for clamping hepatoduodenal ligament and venovenous or cardiopulmonary bypass.
Materials and Methods: Between January 2010 and June 2014, 30 patients of renal mass with renal vein and/or IVC thrombus were treated after classifying the IVC thrombus into three levels on the basis of need for clamping the hepatoduodenal ligament. After excluding renal vein thrombi, level I was described as thrombus located caudal to the hepatic vein. Level II included all retrohepatic, suprahepatic infradiaphragmatic or supradiaphragmatic thrombi reaching till the right atrium. Atrial thrombi were categorized as level III. Level I and II thrombi were managed without venovenous or cardiopulmonary bypass. Level III thrombus required cardiopulmonary bypass.
Results: Of 26 patients with thrombus, 13 had level I thrombus. Of eight cases with level II thrombus, three were retrohepatic, three were suprahepatic infradiaphragmatic and two were supradiaphragmatic. All were removed successfully. Of five patients with level III thrombus, three were operated with cardiopulmonary bypass while the remaining two patients were too sick to be taken up for surgery. The median hepatoduodenal ligament clamp time was 10 min. One patient with level II thrombus had transient liver enzyme elevation.
Conclusion: Renal vein thrombus should not be categorized as level I thrombus. Level II thrombus, irrespective of its relation to the diaphragm, could be managed without venovenous or cardiopulmonary bypass
Case report: MR spectroscopy in pantothenate kinase-2 associated neurodegeneration
We report a case of a 13-year-old girl with Hallervorden-Spatz disease (HSD) or pantothenate kinase-2 associated neurodegeneration (PKAN). HSD is a rare neurodegenerative disorder, which is characterized by a rapidly progressive extrapyramidal syndrome, dementia with optic atrophy, and retinal degeneration. It is associated with accumulation of cysteine-iron complex in the globus pallidi and substantia nigra. The MRI "eye of the tiger" sign is the characteristic. MRI spectroscopy is also characteristic. It shows markedly decreased NAA/Cr values in the globus pallidi and substantia nigra with increased mI/Cr values that suggest of gliosis
Clinicopathological spectrum and the outcome of treatment of upper tract transitional cell carcinoma
Introduction: Disease spectrum of upper tract transitional cell carcinoma (TCC) in Indian patients is not known. Herein, we present data on clinical presentation, pathological characteristics, and the outcome of treatment of upper tract TCC.
Materials and Methods: Clinicopathological data of patients who were diagnosed for upper tract TCC between January 2000 and January 2010 were collected from the hospital information system and case records. Preoperative diagnosis was based on contrast-enhanced computerized tomography of the whole abdomen and urine cytology. Cross tab and logistic regression analysis was done on the effect of various clinicopathological characteristics on the outcome and cancer-specific and recurrence survival were derived.
Results: There were total 40 patients, 35 (87.5%) of them were male. The mean age was 62.7 ± 7.9 years. The most common symptom was gross hematuria present in 30 (75%). Mean tumor size was 2.8 ± 1.2 cm. Median duration of follow up was 36 (12 to 100) months. Laparoscopic nephroureterectomy was done in 27 patients along with bladder cuff excision and seven patients underwent open surgery. Thirty two (88.8%) patients had invasive T stage and high-grade lesions were seen in 24 (66.6%). Lymphovascular invasion was found only in one case and necrosis in 30 (83.3%). Necrosis was found to be the poor prognostic factor. Five-year recurrence-free and cancer-specific survivals were 36.33% and 26%, respectively.
Conclusion: Patients with upper tract TCC present very late with a high-stage disease and a very low 5-year cancer-specific and recurrence-free survivals
