| Diagnosis | Unicameral (Solitary) bone cyst with associated pathological fracture | |
| History | Eight-year-old girl fell out of a tree and landed on her arm. | |
| Findings | Plain radiographs right shoulder and humerous demonstrate a nondisplaced pathologic fracture through a nonaggressive-appearing lytic lesion in the proximal metaphysis of the right humerus. Plain radiographs obtained approximately one month prior to the pathologic fracture demonstrates that the lytic lesion is central and metaphyseal in location, abuts the adjacent growth plate, is minimally expansile, is well circumscribed (narrow zone of transition) and is without associated periosteal reaction. | |

| Diagnosis | Solitary thyroid nodule | |
| History | Patient presents for screening carotid ultrasound and a 3cm Solitary right thyroid nodule was incidentally discovered. The patient denied symptoms of hyperthyroidism or hypothyroidism. | |
| Findings | PREOPERATIVE thyroid nuclear scan was performed: I (131) 7.7 microcurie was administered 24 hours prior to imaging and measurement of the radioactive uptake was 13.8% (normal 8% - 30%). On the day of imaging technetium 99m-pertechnetate 11.0 millicurie was administered thyroid imaging revealed a photopenic region in the lateral aspect of the right thyroid gland. The findings consistent with a cold thyroid nodule. POST-THYROIDECTOMY 1(123) scan demonstrated residual thyroid activity in the thyroid bed with no evidence of extrathyroidal malignancy. I (131) ablation therapy followed with a 185 millicurie dose. | |

| Diagnosis | Solitary thyroid nodule | |
| History | 31 yo female presents for CT following deviated trachea noted on routine CXR. Following CT, she develops increased jitteriness, palpitations, intermittent hot sensation. Ultimately sent for Nuclear medicine I-123 scan for further evaluation of Thyroid. | |
| Findings | Heterogenously enhancing, large mass contiguous with the inferior margin of the right thyroid lobe. No lymphadenopathy or other masses. Mildly heterogeneous and hypoenhancing mass/nodule corresponding to CT, with otherwise normal thyroid uptake on I-123 scan | |
| Differential Dx | Intermediate nodule, likely benign. Since it is not "hot", it will be treated as a cold nodule and the patient is sent for FNA. | |

| Diagnosis | Solitary fibrous tumor of pleura confirmed by histology with immuno-histochemical profile. | |
| History | Female, caucasian, 74 years old, asymptomatic, had a routine chest X-rays done 4 years before. This exam showed a regular mass in the upper third of the right hemithorax (Fig. 1). A CT scan suggested a pleural tumor as a possible diagnosis (Fig. 2). She refused a biopsy or a surgery that was the proposed treatment. She was lost of follow-up. Currently she came back with chest pain and shortness-of-breath and a new radiological study,including chest X-rays, CT scan and MRI (Fig. 3 to 5) showed that the lesion was 3 or 4 times bigger. At this point she accepted the operation. | |
| Findings | Chest X-ray: mass in upper third of right hemithorax that was probably pleural at the CT scan. Chest X-ray four years later showed a massive lesion in the right chest that had the same aspect of the previous CT scan but a lot bigger. The MRI showed a huge inhomogenous mass compressing the diaphragm but without evidences of invasion. | |
| Differential Dx | 1- Solitary fibrous tumor of the pleura. 2- Hemangiopericytoma. 3- Pleural sarcoma. | |

| Diagnosis | Simple (Solitary or Unicameral) Bone Cyst | |
| History | 42 year old WM with no significant prior medical history or recent trauma, presents with 2 month history of left glenohumeral and subscapular pain. Suspicious of rotator cuff pathology, MRI left shoulder requested. | |
| Findings | Routine radiographic examination of the left shoulder reveals a lucent lesion in the proximal humeral metaphysis extending over 5.2 cm superior to inferior. The margins of the lesion demontrate sclerosis. The lesion does not cross the physis. MRI examination of the left shoulder following the administration of intravenous contrast. No rotator cuff or labral pathology noted. Degenerative changes of acromioclavicular joint are noted. There is marrow replacement demonstrated in the humeral metaphysis over a 4.1-cm superior to inferior extent, that does not cross the physeal plate. There is shallow endosteal scalloping and increased signal on fat-suppressed T1-weighted images consistent with proteinaceous material. Minimal expansion is seen anteriorly at the level of the bicipital groove. There is a thin rim of low signal surrounding this lesion, consistent with sclerosis. There is no evidence of pathologic fracture. | |

| Diagnosis | A Solitary plasmacytoma of the left 9th rib in this patient with multiple myeloma. | |
| History | A 59 year old white male presents with a two week history of cough. | |
| Findings | Figure 1: The posteroanterior radiograph of the chest demonstrates an ill-defined left perihilar mid lung zone opacity. Examination of the osseous structures demonstrates absence of a segment of the posterior portion of the left eight rib at the level of the previously described opacity. Figure 2: The lateral radiograph demonstrates an approximately 3 cm soft tissue mass along the posterior aspect of the left hemi-thoracic cage with an incomplete smooth tapered superior and inferior border (relative to the adjacent lung parenchyma) and evidence of destruction of the posterior margin of the left 9th rib. | |

| Diagnosis | Solitary Fibrous Tumor of the Pleura | |
| History | The patient is an asymptomatic 28-year-old white male who was found to have an abnormal chest X-ray during a routine physical exam for special forces selection. Subsequent CT revealed a 4x5 cm mass located in the region of the RUL, and adjacent to the mediastinum. No other abnormalities were noted including mediastinal lymphadenopathy. These prior studies were completed at ????? and ????? in New York, respectively. The present study was obtained to assess for interval change and to prepare for resection. Upon admission the patient's physical exam was totally within normal limits. Patient had also undergone bronchoscopy without biopsy, abdominal CT with contrast, and laboratory work-up for tumor markers to assess for metastases and/or other primaries just prior to admission. These studies were all within normal limits as well. The patient underwent thoracotomy with resection of the mass from the pleural space. Pathological analysis revealed the mass to be a Solitary fibrous tumor involving the parietal pleura without any signs of malignancy. The patient recovered uneventfully and returned to Ft. Drum. | |

| History | She complains that one-week prior to presentation, she developed left hip over after a training exercise that progressed over several hours until she lost range of motion. Extension, abduction and internal rotation (active/passive) were severely limited by pain. The patient demonstrated toe-touch weight bearing. Axillary crutches were used with toe-touch weight bearing. | |
| Findings | AP and frogleg views of the pelvis and left hip were taken to evaluate for possible stress fracture or slipped capital femoral epiphysis. Films demonstrate proper positioning and exposure. The left hip film demonstrates a small | |

| Diagnosis | Multiple myeloma presenting originally as a Solitary lesion (plasmacytoma). | |
| History | 77-year-old male complains of severe upper back pain. | |
| Findings | The examination of 8/14/87 demonstrated a compression fracture of T5 with low signal intensity on T1-weighted images (Film 1) and high signal intensity on T2-weighted images (Film 2). Extension into the left paraspinal soft tissue was seen. Cord compression is noted. The examination of 1/25/90 shows progression of disease to include the vertebral bodies of T5, T6, and a small lesion at T2 (Film 3). Greater extension into the paraspinal soft tissue was noted on axial imaging. | |
