Background Image-guided charcoal injection in suspicious breast lesions for preoperative localization is a procedure that has been increasing over the years because it is safer, faster, and more affordable when compared to needle-wire preoperative localization. To date, no complications have been associated with the method. However, in recent years there have been some reports about charcoal granulomas mimicking malignant lesions in some postoperative patients or in a conservative follow-up. Purpose To report a series of 11 cases which had suspicious imaging findings for malignancy and resulted in charcoal granulomas on histopathological analysis. Material and Methods A database of 1650 patients that attended our center from January 2007 to June 2018 was reviewed and detected 495 patients who had been previously submitted to ultrasound-guided charcoal marking in a breast lesion. Then, patients whose imaging studies were compatible with new suspicious lesions on mammography, breast ultrasound, and/or magnetic resonance imaging and biopsy of this new lesion indicating charcoal granuloma were selected. Results From 495 patients who had undergone charcoal localization injections in previous biopsies, we selected 11 who had new lesions with malignant characteristics on imaging studies but histopathological analysis resulted in charcoal granuloma. Conclusion Charcoal granuloma should be considered in patients with previous preoperative injection localization, since the residual charcoal in the breast tissue may form granulomas and mimic malignant lesions on follow-up imaging studies.

Breast Malignancies

Preoperative localization of breast malignancies using traditional ultrasound and digital techniques can be challenging, particularly after neoadjuvant chemotherapy when the target is not conspicuous. The purpose of this paper is to pictorially present nontraditional techniques that have been helpful in preoperative localization before surgery. We will discuss techniques for breast lesion localization using computed tomography (CT) and magnetic resonance imaging (MRI) as well as axillary lymph node localization using tomosynthesis, CT, and MRI.

Abstract Background Scaphocapitate syndrome is a rare injury where the proximal pole of the capitate rotates 90 to 180 degrees. The proximal pole of the capitate, thought to receive its vascular supply retrograde, is rendered avascular in such cases. However, recent evidence of low rates of avascular necrosis in displaced capitate fractures, and new vascular studies of the capitate, challenge this paradigm. Case Description We report a case of a missed and neglected scaphocapitate syndrome with more than 30 years follow-up. While the patient experienced midcarpal arthritis, the injury had not resulted in capitate proximal pole avascular necrosis as per T1 magnetic resonance imaging studies. Literature Review Missed and chronic cases of scaphocapitate syndrome were reported previously. Successful outcomes were achieved with anatomical reduction in cases without midcarpal arthritis. Salvage procedures or arthroplasty procedures are recommended with the presence of midcarpal arthritis. However, there are no reports of a neglected case with more than 30 years follow-up with preserved vascularity of the proximal pole of the capitate. Clinical Relevance This case illustrates that vascularity of the proximal pole of the capitate can be preserved even in longstanding displaced fractures.

✓ The clinical, radiological, and pathological features of nine cases of intracranial parenchymal schwannoma are described. The clinical course in four patients 23 years of age or younger mirrored the indolent nature of this neoplasm. Imaging studies included computerized tomography in eight patients and magnetic resonance imaging in three. The lesions were well demarcated with only mild surrounding edema. Five tumors were deep within the temporoparieto-occipital region, three were in the cerebellum, and one lay peripherally in the parietal lobe. Over two-thirds of the nine tumors were either cystic (five) or contained areas of cystic degeneration (two). One lesion was frankly hemorrhagic. A variety of imaging characteristics and contrast enhancement patterns were observed, including those of a cyst with a mural nodule and peripheral enhancement. Of the four solid neoplasms, two enhanced homogeneously while the other two demonstrated heterogeneous enhancement. Six tumors were resected totally. The follow-up period ranging from 2 months to 2 years has shown no recurrences. Microscopically, immunohistochemically, and ultrastructurally, the tumors were indistinguishable from peripheral schwannomas. A possible mechanism underlying the histogenesis of these rare lesions is discussed. The importance of recognizing this tumor is stressed, particularly in younger patients, given its benign nature, radiological resemblance to other tumors such as pilocytic astrocytoma, and favorable response to resection.

Late Stages

Secondary lymphedema, more common than its primary variant is essentially a clinical diagnosis. Evaluation should include measurement of limb circumference and volume and appropriate staging protocols to determine the severity of the condition. Imaging studies such as magnetic resonance imaging and lymphoscintigraphy are invaluable in ruling out other causes of extremity swelling and for planning surgical treatment. Conservative measures such as combined decongestive therapy are of prime importance in reducing the limb volume and should be continued to maintain the results of surgical treatment. Pharmacotherapy does not have much role in lymphedema. Surgical options which were initially restricted to debulking procedures in chronic late stages are now gaining more relevance with the advent of physiological techniques to prevent further progression of the condition. Detailed counseling regarding the chronic nature of the disease and the need for regular follow-up along with rehabilitation programs will further improve the management of lymphedema.

This chapter acts as an introduction to Chapters 10–16 and highlights the uses of plain radiography, fluoroscopy, ultrasound, computed tomography, positron emission tomography, magnetic resonance imaging, radionuclide studies, and image-guided intervention. All imaging studies work best if a specific question is asked. This helps to choose both the best modality and protocol to answer the question. The clinical information given will often assist the interpretation of the findings. The more vague the indication for a scan, the less likely that useful information will be provided. Both the requesting clinician and the radiologist need to be clear how the scan result will alter management. Performing imaging procedures that will not alter the outcome is wasteful and unkind to the patient.

Hip fractures may not be evident on initial radiographs but can be demonstrated with special imaging studies. These “occult fractures” can displace if not promptly treated. In a four-year period, 34 occult fractures around the hip in 33 patients were diagnosed in one general hospital. There were 6 men and 27 women, with a mean age of 74 years (22/92). The medical records and imaging studies were retrospectively reviewed. Two patients presented with a displaced femoral neck fracture one month and 10 days respectively after a fall and initial radiographs resulting normal. In the remaining 31 patients with normal radiographs, 30 fractures were detected with MRI obtained at an average of 6.8 days (0/35) from the onset of symptoms, and one with bone scan. Treatment consisted in partial weight-bearing or surgery, depending on the location and displacement of the fracture. Fractures united in all patients treated non-operatively and in those treated with internal fixation. One patient with a displaced fracture underwent a hip arthroplasty. At an average follow-up of 16.7 months (6/46) all patients remained ambulatory. In a selected group of patients with high suspicion of hip fracture, full-sequence MRI proved to be useful for early diagnosis and localization of an occult fracture around the hip.

The Difference

Aim:To compare breast fine needle aspiration (FNA) specimens prepared by conventional smearing (CS) versus monolayer preparation (MP), with respect to the conclusiveness of the cytopathological diagnosis.Methods:From 1992 to 1996, aspirators prepared aspirates themselves by direct smearing onto 2–4 slides. From 1999 to 2003, aspirate preparation was performed in the laboratory, creating a MP, using a Hettich cytocentrifuge. FNA diagnoses were categorised into inadequate (C1), benign (C2), atypical (C3), suspicious for malignancy (C4) and malignant (C5). The reference standard constituted histological follow-up. A conclusive FNA diagnosis was defined as C2 in lesions benign on follow-up and C5 in lesions malignant on histology.Results:From 1992 to 1996, 692 aspirates were processed by CS, whereas from 1999 to 2003, 1301 aspirates were processed by MP. More FNA were ultrasound-guided in the MP group (85.6% versus 21.5%, p<0.001). When compared with CS, MP-prepared FNA had conclusive diagnoses significantly more often (72.8% versus 58.5%, p<0.001). This effect remained significant when corrected for the difference in ultrasound guidance (adjusted odds ratio 1.7, 95% confidence interval 1.3 to 2.2, p<0.001), and was larger for malignant lesions than for benign lesions (51.7% versus 79.9%, p<0.001).Conclusion:Patients presenting with breast lesions can more often be offered a same-day, conclusive cytopathological diagnosis when FNA are prepared by a manual MP processing technique.

Object. The aim of this study was to evaluate both the effectiveness and safety of the treatment of endocrine ophthalmopathy with gamma knife surgery (GKS). Methods. Five patients were included in a prospective study designed to assess the results of GKS of endocrine ophthalmopathy secondary to Graves disease. All the patients completed a 2-year follow-up period. During this period, the patients were evaluated both clinically and by means of additional methods, including computerized tomography and magnetic resonance imaging studies. The minimum dose delivered to the 50% isodose line was 6.5 Gy in all the patients. In all cases, a clinical improvement was observed. The best effect was seen in symptom regression related to soft-tissue involvement. No treatment-related side effects were detected. Conclusions. In light of the results obtained the authors consider that GKS may be a safe and effective way to treat endocrine ophthalmopathy.

Treatment And Prevention

✓ The incidence of the tethered cord syndrome after repair of spinal dysraphism is not insignificant. A retethered spinal cord may also develop after an untethering operation. In order to treat and/or prevent the tethered and retethered spinal cord, the authors developed and successfully used a new method in 12 cases. After complete release and reconstruction of the spinal cord, a Gore-Tex surgical membrane was placed over the cord and fixed to the lateral dural surface with stay sutures. During a postoperative follow-up period ranging from 23 months to 7 years, no further neurological deterioration was observed in the 12 patients and magnetic resonance imaging studies showed no adhesion of the spinal cord to the operative site. It is concluded that this simple new method is effective for the treatment and prevention of tethering and/or retethering of the spinal cord, although a longer follow-up study is required.
