Osteoid osteoma is a benign bone-forming tumor with hallmark of cells directly forming mature bone. accounts for around 5% all bone tumors and 11% male predilection. It occurs predominantly in long bones the appendicular skeleton. According to Musculoskeletal Tumor Society staging system tumors, osteoid stage-2 lesion. classified based on location as cortical, cancellous, or subperiosteal. Nocturnal pain most common symptom that usually responds salicyclates non-steroidal anti-inflammatory...
While chest x-rays (CXRs) represent a cost-effective imaging modality for developing countries like Pakistan, their utility the prognostication of COVID-19 has been minimally explored. Thus, we describe frequency and distribution CXR findings, association with clinical outcomes patients COVID-19.All adult (≥ 18 years) presenting between 28th February-31st May to emergency department tertiary care hospital in who were positive on RT-PCR done presentation, included. A Severity Score (CXR-SS)...
Introduction Initiated in June 2019, this collaborative effort involved 15 public and private sector hospitals Pakistan. The primary objective was to enhance the capacity for pediatric neuro-oncology (PNO) care, supported by a My Child Matters/Foundation S grant. Methods We aimed establish operate Multidisciplinary Tumor Boards (MTBs) on national scale, covering 76% of population (185.7 million people). In response COVID-19 pandemic, MTBs transitioned videoconferencing. Fifteen with...
ABSTRACT Introduction Medulloblastoma (MB) is the most common malignant childhood brain tumor. Molecular subgrouping of MB has become a major determinant management in high‐income countries. Subgrouping still very limited low‐ and middle‐income countries (LMICs), its relevance to with incorporation risk stratification (low risk, standard high risk) yet be evaluated this setting. We describe molecular findings from tertiary care center Pakistan their implications for outcome. Methods Children...
Magnetic resonance imaging (MRI) is regarded as the modality of choice in diagnosis pituitary macroadenomas. Since surgery first line therapy for all adenomas, simple and reproducible MRI classification based on major directions tumour growth an essential tool. SIPAP adenoma describes tumor extension parasellar, suprasellar, infrasellar, anterior posterior directions. We, therefore, evaluated reproducibility reporting adenomas.Forty-nine patients with biopsy-proven macroadenoma were graded...
Aneurysmal bone cysts are tumors of occurring predominantly in the metaphyses long bones and posterior elements spine adolescents young adults. Radiographically, on x-rays they appear as eccentric metaphyseal expansile lytic lesions containing “fluid-fluid” levels. Computed tomographic scan magnetic resonance imaging clearly define fluid-fluid levels; former delineates cortical expansion latter fibrovascular component clearly. Magnetic is particularly useful differentiating aneurysmal from...
BACKGROUND Conventional magnetic resonance imaging (cMRI) is sensitive to motion and ferromagnetic material, leading suboptimal images image artifacts. In many patients with neurological injuries, an intracranial bolt (ICB) placed for monitoring pressure (ICP). Repeated (computed tomography [CT] or cMRI) frequently required guide management. A low-field (0.064-T) portable (pMRI) machine may provide in situations that were previously considered contraindications cMRI. OBSERVATIONS 10-year-old...
Study Design Cross sectional study. Purpose To determine the accuracy of screening magnetic resonance study lumbar spine in diagnosis nerve root compression cases low back pain as compared to routine imaging (MRI) spine. Overview Literature No local has been conducted for this purpose. In an international study, reported sensitivity and specificity MRI protocol detection are 54% 100% respectively. Methods Patients both genders older than 20 years age with any duration or severity who were...
Uterine arteriovenous malformations (AVM) are rare and potentially life-threatening lesions. Patients present with severe vaginal bleeding which usually does not respond to conservative management on most of occasions requires radiological or surgical intervention. We report a case acquired AVM in ruptured caesarean section scar. The patient presented was treated gonadotropin releasing hormone agonist subsequent angioembolisation coiling.
Sturge Weber syndrome also known as mother spot disease belongs to a group of disorders called phakomatoses (neurocutaneous syndromes involving the central nervous and cutaneous systems). It is congenital disorder vasculature meninges, brain, face eyes. Clinically, it usually presents with seizures other neurological complications, including mental retardation, contralateral hemiparesis glaucoma. Its incidence estimated at one case in 20 000-50 000 persons equal frequency boys girls. We...
Background: As the COVID-19 pandemic continues to disrupt global affairs through a variety of manifestations, severe presentation some pediatric patients has emerged, presenting as multisystem inflammatory syndrome in children (MIS-C) that may mimic surgical conditions. Case Presentation: We report case 9-year-old boy who presented with acute, intermittent abdominal pain and fever. Further inquiry suggested hyperinflammatory disorder affecting multiple organ systems. Upon PCR testing,...
The purpose of this study was to assess the knowledge radiology personnel regarding contrast media used in and management associated adverse drug reactions.A questionnaire-based cross-sectional conducted from 21 February 31 March 2019 five major hospitals Peshawar, Pakistan. A 30-item questionnaire adopted existing literature containing both open closed-ended questions authors a pilot among 25 participants face validity tool. universal sampling technique adopted. Descriptive statistics were...
Background Contrast enema (CE) in Hirschsprung's disease (HD) provides a road map to surgeons by ascertaining the transition zone (TZ) and helps pre-surgical planning. In our institute, we use CE as initial investigation for HD carry on till whole colon is fully distended, followed 24-hour abdominal film which also part of international protocol. The main aim this study was evaluate usefulness delayed detecting HD, compare it with gold-standard biopsy results, other imaging features contrast...
We present a case of 14-year-old girl who was diagnosed with Burkitt lymphoma in 2014. She managed chemotherapy and remained remission for 3 years. On her surveillance imaging 2017, left-sided renal neoplastic mass incidentally discovered. underwent nephrectomy pathology the resected specimen revealed small cell tumour kidney features favouring Ewing sarcoma/primitive neuroectodermal tumour. Molecular genetic analysis by fluorescence situ hybridisation performed which showed translocation...
Though various computerized tomography (CT) severity scores have been described for risk prognostication coronavirus disease 2019 (COVID-19), most are challenging to calculate and variable inter-observer agreement. The objective of this study was develop a simple CT score (CT-SS) with good agreement assess its correlation clinical outcome.This retrospective conducted at the Aga Khan University Hospital (AKUH), from April-August 2020. All patients who were PCR positive COVID-19 underwent...
Diffusion-weighted magnetic resonance imaging (DW-MRI) represents a major advance in the early diagnosis of acute ischemic stroke. It can detect edema due to ischemia brain tissue. not only establishes presence and location injury but also relatively new concept is determination infarct patterns seen on diffusion its clinical correlation. Objective To determine frequency various their relationship with functional outcome patient. Materials methods A total 108 patients stroke were enrolled by...
