Talk about the condition:

The disease is discussed as: Chondrosarcoma encompasses 20-25% of all bone sarcomas and is the second most frequent malignant bone tumor of the spine after chordoma (3-12% arise in the spine). The average age of onset is in the adult between the ages of 40- 60 with a greater predisposition for men. The distribution is more common in the flat bones, especially the shoulder and pelvis. The presentation is most commonly of the exostotic type, as a large calcified mass in a vertebral body developing into the paraspinal tissue. The center of the tumor is often calcified with stippling and mottling with underlying bone distruction with a thick cap of sarcomatous cartilage surrounding the calcified mass. The causes include de novo appearance, malignant transformation of an enchondroma, or development from the cartilaginous cap of an osteochondroma. The clinical hx is often one of an indolent pain, swelling, with a progressive increase in size to the point of compression of neighboring organs, nerve root, or spinal cord compression. The cartilage emits a high T2 signal on MRI. Treatment is radical surgical resection due to the fact that the tumor is very refractory to chemotherapy. Incidently, most tumors are discovered late in presentation forcing a piecemeal resection and increased recurrence post-op. The dedifferentiated chondrosarcoma a low-grade tumor often transforms into osteosarcoma or malignant fibrous histiocytoma and becomes responsive to chemotherapy. Prognosis is that a low-grade lesion has a 90% 10-year survival, while high-grade have 20-40% 10-year survival. Follow-up with plain films to screen for recurrence.

The disease is discussed as: Celiac trunk, abdominal aorta, & the iliac arteries are all prone to get aneurysms and may all develop over time together.
An aneurysm is a focal dilation of a arterial vasculature with regard to the primary or adjacent artery. In the abdomen the most typical aneurysm is an abdominal aortic aneurysm (AAA) which is defined as an aortic diameter that should have a normal value at the level of the renal arteries of ranging from 1.4 to 3.0 cm with the average typically being 2.0cm. (1,2). Iliac aneurysms may be associated with AAA about 16% of the time (3) and most of the time it involves the common iliac artery. However, celiac artery aneurysms are one of the more uncommon forms of splanchnic artery aneurysm (4). The celiac trunk gives rise to the left gastric, common hepatic, and splenic arteries.
As in this case, AAA most often occur in the segment of aorta between the renal and inferior mesenteric arteries. Typically, unlike dissecting thoracic "aneurysms," abdominal aortic aneurysms involve all layers of the aorta and do not usually create an intimal flap or false lumen as in this case. Mural thrombus may also develop due to poor blood flow/movement through the aneurysm as seen in the celiac artery aneurysm in this case.
The most common risk factors for developing abdominal aneurysms include age (>60), smoking, sex (>males), race (2x more common in whites as opposed to blacks), atherosclerosis, hypertension, and family history. The USPSTF recommends that men ages 65 – 75 who smoke should get a one time screen for AAA via the preferred modality of real-time ultrasonography (5). CT and MRI are alternative imaging modalities that may also be used.

The disease is discussed as: Multiple myeloma is a plasma cell neoplasm that is characterized by involvement of the skeletal system in multiple sites. It accounts for 1% of all malignancies and is most prevalent in the 70-80 year old range. Symptoms include bone pain, anemia, fever, weight loss, and weakness, as well as neurologic symptoms.
Laboratory findings include elevated ESR, anemia, hypercalcemia and hyperuricemia. Elevated globin levels are present, usually involving IgG, but any of the immunoglobulins may be produced. The plasma cell burden will eventually displace and erode the bony trabeculae and give rise to the musculoskeletal symptoms.
Classically, multiple myeloma will appear as osteolytic lesions. These arise predominantly in the verterbral bodies, ribs, skull, pelvis and femur. However, diffuse skeletal osteopenia may be observed without focal lytic lesions. Pathologic fractures are common.
Both plain films and MDP scintigraphy have a significant false negative problem: Plain film false negative 9-25%; and, MDP false negative 40-60%. http://www.med.harvard.edu/JPNM/TF94_95/Jan17/WriteUpJan17.html

Explain the disease:

The disease is discussed as: Duplicated renal collecting systems represent renal units with two distinct pyelocalyceal systems associated with either a single or double ureter. In the case of two distinct ureters, the ureters either join together along their course and form a single ureter, or they both insert individually on the bladder. This anomaly presents either unilaterally or bilaterally, and is estimated to occur in up to fifteen percent of the population. Most individuals with a duplicated renal collecting system remain asymptomatic with their anomaly being found incidentally on imaging studies. Those patients who become symptomatic with their duplicated collecting system generally have two distinct and complete urters, and are prone to developing obstruction, reflux, and infection.
A duplicated renal collecing system forms by one of two ways. The first results from the embryologic bifurcation of a single ureteral bud prior to the bifurcation of the ampulla, and produces either a bifid ureteral pelvis or a bifid ureter which joins distally prior to bladder insertion. The second results when two distinct embryologic ureteral buds arise from the Wolffian duct, giving rise to two complete and separate ureters which insert separately into the bladder. In this second case, with two separate ureters, the upper pole ureter drains below and medial to the lower pole ureter at its insertion. According to the Weigert-Meyer rule, the upper pole ureter is prone to obstruction and hydronephrosis as well as ureterocele formation, while the lower pole ureter is prone to refulx and at is risk for pyleonephritis. Additionally, this upper pole ureter may insert ectopically inferior to the bladder (e.g. urethera, or vagina), causing continual leakage of urine in females (not the case in males as the ectopic insertion is proximal to the external uretheral sphinter).

Describe the condition in detail:
|
The disease is discussed as: Pulmonary sequestrations are masses of pulmonary parenchyma which do not communicate with the central airways through a normal bronchial connection, if at all. In addition, their blood supply is from the systemic circulation. Demonstrating the feeding systemic arterial vessels is the key point in differentiating sequestrations from bronchogenic cysts, lobar atelectasis or other abnormalities.
Extralobar sequestrations are congenital in origin and contain their own pleural covering. Most (over 90%) are left-sided and associated congenital anomalies, such as congenital diaphragmatic hernias and congenital heart disease, are frequent. The venous return is through the systemic circulation. These may not only be seen adjacent to the mediastinum, but also in the mediastinum, pericardium, diaphragm, and retroperitoneum. Rarely is a connection with the bronchial tree present and rarely are they symptomatic. A majority of these are noticed incidentally.
Intralobar sequestrations are located within the lung and have no separate pleural coverings. Although their arterial supply is systemic, their venous return is through pulmonary veins. Compared to the extralobar form, intralobar sequestrations are likely acquired lesions, possibly due to chronic bronchial obstruction or postobstructive pneumonia. Connection to the bronchial tree may be present. This variety may produce symptoms as a result of infections.

The disease is discussed as: • most common congenital vascular anomaly of the aortic arch
• with the anterior aorta, the ARSA creates a vascular ring around the mediastinal structures, including the trachea and esophagus
• most often asymptomatic
• may cause wheezy or stridorous breathing; usually picked-up by 2 years
• dysphagia ("dysphagia lusoria"), particularly in patients with a wide based take-off of the aberrant vessel ('Diverticulum of Kommerell').
• widened mediastinum silhouette on plain PA/AP chest films
• posterior notch on barium swallow/esophagogram
• associated with many types of congenital heart disease, Down's, VCFS (Velo-Cardio-Facial), DiGeorge's, Dubowitz's, and Edward's syndromes

Talk about the condition:
|
The disease is discussed as: Venous sinus thrombosis is caused by thrombus formation in the dural venous sinuses or cerebral veins. It is an uncommon disorder (2-7 per million) which can have serious complications. Causal factors include local (regional infection, trauma, neoplasm) and systemic (dehydration, hypercoagulable states, pregnancy, oral contraceptives). Clinical presentation includes headache, neurologic deficits or seizures. The superior sagittal sinus is most commonly affected, followed by the transverse and sigmoid sinuses. Complications include venous infarcts, intracerebral hemorrhage and intracranial hypertension.
On noncontrast CT, the thombosed sinus is usually hyperdense. This is nonspecific as dehydrated patients, adjacent subdural or subarachnoid hemorrhage or elevated hematocrit can cause increased sinus attenuation. On contrast enhanced CT, the empty delta sign is a central defect from thrombus surrounded by contrast enhanced blood. On MRI, absence of a flow void or abnormal signal within the sinus is seen.
MR venography with two-dimensional time-of-flight is used due to high sensitivity for slow flow compared to 3D TOF. Contrast enhanced MRV improves visualization of small vessels. CT venography is a rapid and accurate method for evaluating the venous sinuses. Disadvantages include ionizing radiation exposure and need for iodinated contrast material.

MedPix-VQA Dataset
The MedPix-VQA dataset is a version of the data found at MEDPIX-ClinQA, specifically modified to address an image overlap issue that would result from directl splitting the original dataset. This overlap can lead to a model potentially seeing the same image during both training and validation, potentially leading to bias or data leakage.
Key Modifications:
- We have modified the dataset to ensure no image overlap between the training and validation sets. This was done by grouping the data based on image hashes and ensuring that all instances of an image (with different Q&A pairs) are either in the training set or in the validation set, but not in both.
- This ensures that the model's evaluation is done on truly unseen images, providing a more accurate assessment of its generalization performance.
Dataset Structure:
The dataset consists of the following columns:
image_id: The ID for each image.mode: The mode or context for the image.case_id: The unique case identifier.question: A textual question related to the image.answer: The corresponding answer to the question.
Dataset Split:
- Training Set: 17420 examples (85%)
- Validation Set: 3080 examples (15%)

})
Usage:
This dataset is designed for training and evaluating Visual Question Answering (VQA) models in the medical domain. It contains images from MedPix, a well-known medical image database, paired with questions and answers that focus on image interpretation.
