Abstract

Identification of certain abnormalities of the chest wall can be extremely helpful in correctly diagnosing a number of syndromic conditions and systemic diseases. Additionally, chest wall abnormalities may sometimes constitute diagnoses by themselves. In the present pictorial essay, we review a number of such conditions and provide illustrative cases that were retrospectively identified from our clinical imaging database. These include pentalogy of Cantrell, Klippel-Feil syndrome, cleidocranial dysplasia, Poland syndrome, osteopetrosis, neurofibromatosis type 1, Marfan syndrome, Gardner syndrome, systemic sclerosis, relapsing polychondritis, polymyositis/dermatomyositis, ankylosing spondylitis, hyperparathyroidism, rickets, sickle cell anemia, thalassemia, tuberculosis, septic arthritis of the sternoclavicular joint, elastofibroma dorsi, and sternal dehiscence.

  Fig. 1 Pentalogy of Cantrell.Chest CT scan of 25-year-old male with Pentalogy of Cantrell, status post remote Fontan procedure for complex congenital heart abnormality, shows absence of sternum resulting in partial herniation of right ventricle (arrowheads). Note extracardiac Fontan conduit (arrow), multiple mediastinal collateral vessels, and bilateral pleural effusions.

• 

  Fig. 2 Klippel-Feil syndrome.Chest radiograph of 39-year-old female with Klippel-Feil syndrome shows hypoplastic right humeral head (arrow), dysmorphic right scapula and glenoid, high-riding left scapula-Sprengel deformity (arrowheads), and multiple upper rib deformities. There is right ventriculo-peritoneal shunt.

  Fig. 3 Cleidocranial dysplasia.Chest radiograph of 3-year-old male with cleidocranial dysplasia shows absence of both clavicles and slanting of ribs. Expected location of clavicles is outlined by dashed line.

• 

  Fig. 4 Poland syndrome.10-year-old female with Poland syndrome.A. Chest radiograph demonstrates hyperlucent left hemithorax. B. Chest CT with coronal reformation shows absence of left pectoral muscles. Note normal right pectoral muscles (arrows).

  Fig. 12 Ankylosing spondylitis.A. CT with sagittal reformation in 76-year-old male with ankylosing spondylitis shows diffuse ankylosis of thoracolumbar spine. B. Chest CT with sagittal reformation in different patient with ankylosing spondylitis shows acute Chance fracture in upper lumbar spine (arrow).

  Fig. 15 Rickets.Frontal chest radiograph of 3-month-old premature-born female with rickets demonstrates healing fractures of left posterior 6th and 7th ribs (arrows), nodular widening of bilateral costochondral junctions-rachitic rosary (arrowheads) and fraying of proximal humeral metaphyses (dashed outlines).

  Fig. 16 Sickle cell anemia.Frontal (A) and lateral (B) chest radiographs of 39-year-old female with sickle cell anemia demonstrate H-shaped vertebrae (arrowheads) and left humeral head subchondral sclerosis (arrow), consistent with avascular necrosis.

• 

  Fig. 17 Beta thalassemia.Chest CT scan of 44-year-old male with beta thalassemia intermedia shows diffuse expansion of osseous medullary spaces, coarsened trabeculations of ribs and vertebrae, and paravertebral extramedullary hematopoiesis (arrows).

• 

  Fig. 18 Beta thalassemia.Sagittal T1-weighted MRI of spine in 9-year-old male with beta thalassemia major shows diffuse abnormally low signal intensity of bone marrow related to active red marrow and iron deposition from multiple blood transfusions. Note that bone marrow (asterisk) is of significantly lower intensity than intervertebral disks (arrowhead).

• 

  Fig. 19 Tuberculosis.Chest CT in bone (A) and mediastinal (B) windows of 23-year-old male with active post-primary pulmonary tuberculosis and spondylitis demonstrates irregular lytic lesion involving superior endplate of dorsal vertebra (arrow) and associated perivertebral abscess (arrowhead).

• 

  Fig. 20 Septic arthritis of sternoclavicular joint.Chest CT in bone (A) and mediastinal (B) windows of 41-year-old male, who developed septic arthritis of right sternoclavicular joint several weeks following penetrating injury to chest, demonstrates erosive lesions in right clavicular head and manubrium (arrowheads) consistent with osteomyelitis, and adjacent phlegmonous collection (arrows).

• 

  Fig. 21 Elastofibroma dorsi.Chest CT scan of 81-year-old female shows bilateral soft-tissue masses between scapulae and rib cage (arrows), consistent with bilateral elastofibroma dorsi.

Chest radiograph shows fractures and misalignment of many sternal wires (arrows). B. Chest CT with coronal reformation shows separation of sternotomy edges (arrowheads).
