R.I.C.H.
Grand Rounds
October 2005
Speaker: Jay C. Bradley, MD
Discussant: Michael J. Shami, MD
Rapidly Involuting Congenital Hemangioma
Report of Case:
• Premature female referred for choroidal hemangioma OS discovered at ROP screening exam
• 1 pound 10 ounces, 27 weeks gestational age at first exam
• MRI of brain/orbits/liver c/s contrast NL
Types of Congenital Hemangiomas
• Typical infantile hemangioma
• NICH (Non-involuting congenital hemangioma)
• RICH (Rapidly involuting congenital hemangioma)
Typical Infantile Hemangiomas
• 1-2 % of neonates
• Up to 12 % of Caucasian infants by 1 year
• Female > Males (3-5:1)
• Up to 23 % of premature infants
• Manifest postnatally (median of 2 weeks)
Typical Infantile Hemangiomas
• Grows rapidly during 1st year of life
• Involutes slowly from 1 – 7 years
• Completely regresses by 8 –12 years
• Glucose transporter-1 protein present
N.I.C.H.
• Present before birth
• Does not involute
• Grows in proportion with patient
• Similar to RICH in appearance, location, size, and sex distribution
R.I.C.H
• Fully grown at birth• Male = Female• Diagnosis possible as early as 12 weeks
gestation by U/S• Rapid 2nd trimester growth with 3rd trimester
plateau• Involuted rapidly by 12 – 18 months• No glucose transporter-1 protein
R.I.C.H.
• Most common locations– Head & neck
– Extremities, close to joint (ie elbow, shoulder, knee or hip)
– Rare on trunk / liver / sacrococcygeal area
– No previously reported choroidal involvement
• Inhomogeneous areas and larger flow voids on MRI
• Aneurysms on angiography
Possible Theoretical Model

Interferon (trophoblastic origin)
-
1. 6 X greater in 1st than 3rd trimester2. RICH/NICH from localized area of
low [IFN]3. Typical IH from sudden decrease in
[IFN] without placental circulation
Treatment• Observation, observation, observation!!! (>90 %
require no treatment, without relation to size)• Unless…
– Equivocal diagnosis (rule out congenital fibrosarcoma and other malignancy)
– Ulceration, hemorrhage, visual obstruction– AV shunting with CHF– Kasabach-Merritt phenomenon– Residual excess skin or telangiectasias after rapid
involution
• Then excision +/- steroids +/- interferon
Skin / Lid hemangiomas
• Usually capillary type• Induces astigmatism• May cause amblyopia• May require intervention
Sterker I, Grafe G. Strabismus. 2004 Jun;12(2):103-10.
Choroidal hemangiomas
• Usually cavernous type
• Isolated – Reddish orange– Well-circumscribed– Discovered during routine exam or secondary
to induced hyperopia from tumor or serous detachment
– Not usually associated with Sturge-Weber syndrome
• Diffuse– “Tomato catsup” fundus
– May be dicovered during Dx/Tx of associated developmental glaucoma or amblyopia in children
– Associated with Sturge-Weber syndrome• Encephalotrigeminal angiomatosis
• Ipsilateral facial nevus flammeus (port-wine stain) V1/2 (87%)
• Sporadic inheritance
• Seizures (72-93%)/ glaucoma (30-71%) / choroidal hemangioma (40%) / MR (50-75%)
Choroidal hemangioma
• Overlying cytic change alone to frank neurosensory detachment secondary to choroidal exudation and RPE dysfunction
• Hard exudates are not commonly seen• Treatment
– No symptoms observation
– Serous detachment affecting fovea Laser photocoagulation, cryopexy, external beam and plaque radiation, or PDT
