Question Answer
Holly leaf appearance Asbestosis
Hot cross bun signMultisystem atrophy -C The exact cause is not known but it is mostly due to selective loss of myelinated transverse pontocerebellar fibers and neurons in the pontine raphe and sparing of the pontine tegmentum and corticospinal tracts. Multisystem atrophy (MSA) is a sporadic progressive neurodegenerative disorder of adult onset, involving the basal ganglia and the olivopontocerebellar complex to varying degrees. It commonly presents with Parkinsonian symptoms and cerebellar ataxia and depending on which of these symptoms predominates, is classified as MSA-Parkinsonian predominant(MSA-P) and MSA-Cerebellar predominant (MSA-C) respectively. To diffrentiate between MSA, and especially MSA-P, from Parkinson's disease (PD), certain findings on MRI may be a useful aid to clinical diagnosis. Atrophy of the putamen and brainstem and abnormal signal in the middle cerebral peduncle are found in a significant number of patients with MSA, while they are almost never found in PD patients. Hot cross bun sign is a manifestation of pontine atrophy in MSA and is more commonly found in MSA-C.
Hot cross bun skull (Gross appearance -NOT RADIOLOGICAL APPEARANCE)Prominence of suture lines of skull and prominence of frontal and parietal eminences leading to 'bossing' of head ('hot-cross-bun appearance') in newborns. Its usually seen in Congenital Syphilis ,Rickets . Also in Cleido cranial dysplasia.

1-2-3 Sign(Garland's triad (also known as the 1-2-3 sign or Pawnbrokers sign) is a lymph node enlargement pattern which has been described in sarcoidosis:

1)right paratracheal nodes
2)right hilar nodes
3)left hilar nodes
Hilar lymphadenopathy is symmetrical and usually massive. These so called potato nodes don't usually abut the cardiac border which distinguishes it from lymphoma.

Involvement of right paratracheal nodes reflects the ease with which these nodes are identified on plain radiography.

Left paratracheal and aortopulmonary nodes are frequently enlarged but harder to identify)
