ultrasound image cruciate ligament tear                rupture of medial cruciate ligament    

    

These are ultrasound images of the right knee joint following a motorcycle accident. There is a curvilinear echogenic structure within the medial part of the right knee joint cavity. Diagnosis: traumatic rupture of the distal insertion of the medial cruciate ligament, which now floats within the fluid distended (possible hemorrhagic) joint space. Images courtesy of Mr. Shlomo Gobi, Israel.

 

2) Epidermoid cyst:

 

ultrasound image of epidermoid cyst      color doppler image of epidermoid cyst

Sonography of a mass on the dorsal part of the chest was done to study a mass of 2.5 cms. Images reveal a hypoechoic mass of inhomogenous appearance measuring 2.5 x 1.3 cms. It is cutaneous in location and shows no vascularity within on color doppler imaging (image on right). No calcification is seen. These ultrasound images suggest a diagnosis of epidermoid cyst or what was often called a sebaceous cyst. Images by Dr. Joe Antony, Cochin, India, using Toshiba, Nemio XG color doppler machine.

3) Ultrasound image of transient synovitis of hip joint in a child:

ultrasound image of pediatric hip     ultrasound image of transient synovitis

Sonography of the hip joints was done in this 5 yr. old child to c/o pain and swelling in the right hip. Ultrasound images show anechoic fluid collection around the right hip diagnostic of synovitis. The synovial fluid collection here measures 3 x 0.8 cms. The normal left hip joint is also shown for comparison. Ultrasound images courtesy of Dr. Ravi Kadasne, who used a Philips iU 22 machine.

 

4) Ultrasound image of olecranon bursitis:

olecranon bursitis  

This patient had pain and swelling of the left elbow. Sonography of the elbow shows a cystic lesion containing clear fluid over the tip of the elbow. The lesion is located between the skin and the underlying olecranon process of the left ulna. This ultrasound image is diagnostic of olecranon bursitis. Image courtesy of Dr. Ravi Kadasne, UAE. The machine used here is the Philips IU 22.

5) Ultrasound images of inguinal hernia:

 sonography of inguinal hernia

These ultrasound images show echogenic, linear/ tubular structures (intestine) within the left scrotal sac, just above the left testes, extending to the left inguinal canal s/o left inguinal hernia. (Images taken using a Philips iU 22 Ultrasound machine, by Dr. Ravi Kadasne, MD, UAE.

6) Sonography and Color Doppler imaging of Hemangioma in infant:

subcutaneous hemangioma    Color Doppler image of cavernous hemangioma

An infant present with a large reddish patch in the right lumbar region. Ultrasound image (left) shows a hyperechoic lesion of about   2.3 cms. in the subcutaneous layer. Color Doppler image (right) shows the lesion to be markedly vascular. These ultrasound and color Doppler images are diagnostic of Hemangioma, possibly cavernous type. Images courtesy of Dr. Ravi Kadasne, UAE.

7) Hypertrophy of the Abductor Hallucis muscle of the foot:

Ultrasound images showing hypertrophied muscle on medial part of plantar aspect of the foot:

showing the thickened abductor Hallucis (long section)      transverse section through the abductor Hallucis of both sides

Hypertrophy of abductor Hallucis of right side

This patient presented with persistent pain in the sole of the Rt. foot. Sonography of the plantar aspect of the right foot showed markedly thickened muscle along the medial aspect of the plantar region. The left foot was also imaged and showed the normal Abductor Hallucis muscle. It was concluded that the ultrasound images (above) showed a hypertrophy of the right abductor Hallucis muscle. The right abductor Hallucis showed a thickness of 2.1 cms. while the normal left side showed a thickness of about 0.7 cms. Ultrasound images are courtesy of Dr. Ravi Kadasne, MD, UAE.

8) Rib fracture:

Ultrasound image of rib fracture:

sonography in rib fracture     3-D ultrasound image of rib fracture

This patient had a history of trauma to the chest. Sonography of the thorax (chest) showed a breach in continuity of the rib shown above (arrow). 3-D ultrasound image (image on right) shows fracture of the rib with small hematoma collecting anterior to the fracture site. The hematoma is seen as an anechoic collection. High resolution sonography/ ultrasound is now increasingly being used in imaging the skeletal system, especially when in a superficial location. Ultrasound images are taken using Philips IU22 system and are courtesy of Dr. Ravi Kadasne, MD, UAE.

9) Fracture radius with hematoma formation:

fracture of radius with hematoma formation     Ultrasound image of soft tissue hematoma

This X-ray of the wrist and forearm shows a fracture of the distal end of radius. Ultrasound image on right shows large hyperechoic collection (arrowheads) anterior to the fracture site. X-ray image also shows the soft tissue swelling caused by hematoma (blue arrows). This child had a history of bleeding disorder. Images courtesy of Ravi Kadasne, MD, UAE.

10) Intracranial mass/ Intracranial dermoid or epidermoid:

Dermoid mass or CNS Dermoid:

Color Doppler image of CNS dermoid    Ultrasound image of CNS dermoid

the mass compressing on the brain (on sonography)    cranial and CNS ultrasound image

This middle aged female patient presented with a mass in the parieto-occipital region. Sonography of the skull was done to image the mass which was close to the midline. Ultrasound images show a mass of mixed echogenicity with both solid and cystic components within the cranial vault (intracranial region), which has eroded the cranial vault to bulge outward. Particulate matter was seen floating the fluid component of the mass. The cerebral hemishperes appear to be compressed upon by the mass (M) via the dura mater. The meninges appear to be preserved though displaced inward by the mass. Color Doppler image (top row- left) suggests poor vascularity of the intracranial mass. These ultrasound and Color Doppler images suggest a dermoid tumour inside the cranium (CNS dermoid). Dermoids are known to occur in such locations though, are rare. The other diffferential diagnoses are meningioma and epidermoid cyst. But the midline location favors a diagnosis of dermoid cyst. Ultrasound images are courtesy of Dr. Ravi Kadasne, UAE.

11) Baker cyst:

Large cystic lesion in left popliteal fossa:

sonography of Baker cyst    Power Doppler image Baker cyst

Transverse section COlor Doppler image Baker cyst    Showing relation of Baker cyst to popliteal artery

This middle aged female patient presented with a large mass in the left popliteal region which was seen on extension of the knee joint. Ultrasound images of the popliteal fossa show a large cystic mass of 5.7 x 2.8 cms. with few echogenic particles within a primarily clear fluid. The cyst is in close relation to the left knee joint; however, these images did not reveal clear communication with the synovial space of the knee joint. The popliteal artery was visualized on Color Doppler imaging, and was clearly separate from the cyst, ruling out the possibility of aneurysm of this vessel. Final diagnosis: Baker cyst (also called Baker's cyst).
