RESUMO
BACKGROUND: Congenital pericardial absence is an uncommon cardiac anomaly that is typically asymptomatic and commonly misdiagnosed due to a lack of symptoms or atypical symptoms. Pericardial agenesis (PA) should be considered one of the differential diagnoses when the patient presents with chest pain. This case shows how the diagnosis of pericardial agenesis is made exclusively using multi-modality imaging, starting from findings in a basic chest radiograph to cardiac MRI, while also demonstrating the classic signs seen in this condition. Magnetic resonance imaging of the heart is the gold standard for determining the absence of pericardium in the prognosis. CASE PRESENTATION: A 32-year-old male who presented with chest discomfort and radiating pain to his back and left shoulder mimicking myocardial infarction with normal ECG and enzyme markers. A chest radiograph (taken 24 h apart) demonstrates the left lateral position of the heart and the bulging contour of the left heart border, a lucent area between the aorta and pulmonary artery. Subsequently, cardiac MRI reveals left pericardial agenesis. CONCLUSIONS: This article provides insight into a rare differential to consider in a young patient presenting with chest discomfort. This case shows how the diagnosis of pericardial agenesis is made exclusively using multi-modality imaging, starting from findings in a basic chest radiograph to cardiac MRI, while also demonstrating the classic signs seen in this condition.
RESUMO
Chronic recurrent multifocal osteomyelitis (CRMO) is a rarely reported autoimmune inflammatory condition affecting children and young adults. The typical complaint is recurrent severe bone pain at multiple sites; often imaging suggests features of osteomyelitis or malignancy. However, the biopsy is always negative for any growth in culture and histopathology detects only inflammatory cells. This is a diagnosis of exclusion with various diagnostic criteria. We had a 20-year-old male presenting with recurring pain and swelling in the right hand and left foot for more than seven months. Imaging revealed bone marrow edema with the expansion of bone and sclerosis involving the third metacarpal of the right hand and first metatarsal of the left foot. Acute phase reactants were mildly raised with biopsy showing inflammatory cells. However, the cultures grown from the lesion were sterile. After comparing it with the various diagnostic criteria, a diagnosis of CRMO was made.
RESUMO
Cysticercosis results in humans when infected with the larval stage of taenia solium which is called cysticercus cellulosae. The target organs usually involved are the brain, eyes, spine, and skeletal muscles. The ocular form of cysticercosis can affect the intra-ocular structures or involve the orbital adnexa. Intraocular involvement is relatively common and is readily diagnosed owing to its obvious visibility on a basic slit-lamp examination, however, affection of orbital adnexa is infrequent. Moreover, solitary involvement of one of the extraocular muscles is rare and difficult to diagnose as it presents with a spectrum of non-specific symptoms. We report a rare case of orbital cysticercosis with a solitary left superior rectus muscle involvement, who presented with recurrent on and off lid swelling extending for two years with double vision and restriction of downward gaze.
