Pathology demonstrated a immature teratoma. A partly liquefied lymphnode is seen with infiltration of the surrounding subcutaneous fat.

Cystic Abdominal Masses in Children

A year-old female, with a history of previous surgery and radiotherapy for carcinoma of the cervix, presented with an open wound over the symphysis pubis. The uterus is displaced towards the side of torsion. There are few clinical symptoms, most often only a palpable mass.

Although the differential diagnosis is extensive, appropriate use of plain radiography, CT, and MR imaging can help define anatomic extent and, along with guidance from clinical history and biopsy, aid in making the final diagnosis. However HOC can also be an incidental finding in an asymptomatic patient.

Look for fluid anterior to the liver or in Morrisons pouch to exlude a lymphangioma.

Cystic Abdominal Masses in Children

Partial tears most commonly affect the distal head of the rectus femoris. A higher diagnostic yield can be achieved by targeting nonsclerotic, nonnecrotic areas and obtaining more tissue with larger bore needles and multiple passes [ 45 ].

Magnetic resonance imaging has increasingly gained relevance since, besides differentiating parenchymal from pleural lesions, this method presents a better spatial resolution and, if performed during the menstrual period, it can identify glandular tissue in the affected site hyperintense foci on T2-weighted images This medial compression is increased with muscle actions, resulting in more stress injuries in this area.

Sometimes a torticollis is noted. A cyst with a fluid-fluid level is seen. The swelling disappeared on antibiotic treatment. After release of the oocyte, the dominant follicle collapses, and the granulosa cells in the inner lining proliferate and swell to form the corpus luteum of menstruation.

Nerves from the lumbar plexus that descend into the thigh include the femoral, obturator, and lateral femoral cutaneous nerves Figures 56, Strains are stretched or torn muscles or tendons. Metastases Metastases are the most common malignant neoplasm of the pelvis, specifically the sacrum, with lung, breast, kidney, and prostate carcinoma the most frequent primary neoplasms [ 11 ].

The final diagnosis on imaging and on clinical examination was a venous malformation. The infection is the result of a scratch or bite of a cat. If the patella is cut away from the quadriceps femoris, the articularis genu muscle is seen. But when pressure was applied with the probe this proved to be debris.

The quadriceps are in contact with the femur throughout its length, making these muscles susceptible to compression forces. Surgical treatments include arthroscopic drilling of intact lesions, and drilling and replacement of cartilage plugs.

The descending branch artery is used for bypass and reconstruction surgery. Due to the wide spectrum of radiographic appearances, ES can mimic most malignant and a few benign entities, including osteomyelitis, eosinophilic granuloma, and giant cell tumor [ 8 ].

Bypass for peripheral artery disease. Here an image of a newborn with an abnormal thyroid test. MRI has become the imaging modality of choice, as it has excellent specificity and sensitivity to the early stress changes seen in bone.

Be aware that fat and hemorrhagic components can demonstrate high T1 signal on pre-contrast images and should not be confused with enhancement of solid components. Axial CT scan of another patient demonstrates more typical appearances of chondrosarcoma with endosteal scalloping arrow and chondroid matrix arrowhead c.

It was decided to wait and see and the nodes slowly shrunk. The anterior division of the femoral nerve is further divided into anterior cutaneous branches and muscular branches.

The images are of a fourteen-year-old boy with a painless swelling in the left neck. The muscles are more resistant to injury if struck while contracted and nonfatigued.

Nephroblastoma here an one and a half year old girl with a palpable tumor in the left abdomen. It begins at the anterior superior iliac spine, and inserts on the medial aspect of the tibia. The healing process of insufficiency fractures involving the pubic rami can lead to significant callus formation, mimicking a tumor Figure 13 a.

On US a cystic mass can be seen with calcifications. The cyst was partially resected, the common wall with the duodenum was left in situ. AP radiograph a of the pelvis reveals a vague mixed density abnormality diffusely involving the right ilium circle.

It often accompanies other conditions such as hypertension, diabetes, high cholesterol, and stroke. In doing so, you can easily exclude cysts of the liver, spleen, kidneys, pancreas and choledochal duct.

Cystic masses in the abdomen of a child are common. Many of these are discovered with prenatal ultrasound. Others are detected when a child has abdominal complaints and imaging is performed.


The cyst is either the cause of the complaints or an incidental finding. In this pictorial essay we will show. Sr. Editor, Mulher, 29 anos, previamente hígida, procurou o serviço de emergência com queixa de dispneia súbita.

No exame físico o murmúrio vesicular estava abolido em todo o hemitórax direito. Conclusions. Magnetic resonance imaging is an essential tool in the investigation of a patient with suspected temporal lobe pathology. Various conditions may affect this anatomic region, and, therefore, classification of imaging findings into specific groups may help.

MRI allows for visualization of the bundles of Probst—evidence that callosal fibers are not really agenetic but heterotopic, lying parasagittally on both sides and giving the lateral verticle appearance of moose head or viking helmet on coronal images.
