Aspergillosis Spectrum
- fungus ball
- preexisting cavity, bulla, bronchiectasis
- saprophytic
- sarcoidosis, CF
- Hemoptysis
- round opacity within cyst or cavity
- air crescent
- mobile
- pleural thickening
Semiinvasive Aspergillosis
- Mildly immunosuppressed hosts
- focal consolidation > cavity > air crescent > thick-walled cyst > fungus ball
Invasive Aspergillosis
- Immunocompromised hosts
- granulocytopenia
- single or multiple nodules
- cavitation
- air crescent
- “Halo” sign on CT
Allergic Bronchopulmonary Aspergillosis
- Hypersensitiviy reaction to aspergillus in mucous plugs
- mucoid impaction
- asthmatic patients
- lobar consolidation
- chronic, upper lobe scarring and bronchiectasis
Hardware
What are those devices called and what are they used for? Here are some helpful links I use:
Gallery of Medical Devices, Part 1. Radiographics.
Cord Insertion Types
Required element in a complete >14wk OB ultrasound report.
Cord Insertion types: central, eccentric, marginal, and velamentous
Hypertrophic Olivary Degeneration
- signal within the medullary olive due to transsynaptic degeneration from lesions along the Guillaine-Molaret triangle
- seen after posterior fossa tumor resection (link)
- akin to Wallerian degeneration
Blount’s disease
- tibia vara, causes genu varum.
- metaphyseal-diaphyseal angle >11 degrees
- bilateral ~infantile type
- pain in adolescent
Vascular Anomalies, ISSVA Classification
2 categories: vascular tumors or vascular malformations. Distinction determines therapy.
Vascular Tumors
- infantile hemangiomas: grow rapidly after birth, GLUT1+
- congenital hemangiomas (RICH and NICH): fully mature at birth, GLUT1-
- Tufted angioma
- Kaposiform hemangioendothelioma
- Spindle cell hemangioendotheliomas
- Dermatologic acquired vascular tumors
Vascular malformations (slow)
- capillary malformation (port-wine stain, telangiectasia, angiokeratoma)
- venous malformation
- lymphatic malformation
Vascular malformations (fast)
- arterial malformation
- arteriovenous fistula
- arteriovenous malformation
Status Marmoratus
Status marmoratus is the presence in full-term infants of basal nucleus lesions resulting from acute total asphyxia. The lesions have a marbled appearance caused by neuronal loss and an overgrowth of myelin in the putamen, caudate, and thalamus. – wiki
